Quartz composer 4.0_Object Detection by Color

Hi,
I search for a project to develop a quartz compositions with a color tracking.
I can't finish my composition.
I think have a good compositions but my "object tracking" is not visible.
Can you help me to find a good solutions?
Thank you

  • Quartz Composer Files not opening

    Hi, I am new to Quartz Composer. I hope I am posting this query in the right area.
    Browsing the net to get info on doing motion detection with QC, I have come across a number of downloadable sample compositions. However, when clicked on, the following message appears -"the downloaded composition is unsafe and cannot be run inside webkit".
    Control clicking allows me to download the file anyway but on launching QC a message reads that the file was not restored successfully, listing the problems (eg. > Macro Patch Cannot create node of class "QCQueue" and identifier "(null)"etc.)
    From discussions on the pages that these compositions are posted on, it is clear that others have downloaded and used these files without problems.
    I have QC Version 2.0 (16) running on a MacBook Pro with Mac OS X 10.4.11
    Any ideas?
    Many thanks!

    In Quartz Composer, some of the patches are deemed as "unsafe" because they could potentially be used for malicious purposes, such as the video input or audio input patches. I'm pretty sure that Kineme ( http://kineme.net/ ) has a plugin that lets you work around those limitations, though.

  • How to separate image from alpha using Quartz Composer?

    Cross posting here and in the developers forums... (sorry for any duplication - also posting to the QC mail list)
    I'm attempting to construct a Quartz Composer composition that will take an image containing transparency, and — within the structure of that composition — disect the image so that I can perform separate operations on the alpha mask and the full image (i.e. as if the mask did not exist).  This would be akin to opening a PNG or TIFF in GraphicConverter, then accessing the images I want via Show Alpha Channel and Remove Alpha Channel.
    I'm able to easily access the alpha channel by applying a Color Martix patch to the image, but I can't seem to figure out how to get to the full "unmasked" image.
    Can anyone nudge me in the right direction as to how I could remove the alpha mask from an image?
    Thanks!!
    John

    Hi John,
    You could use the Core Image Filter to extract the Alpha channel as a mask, and then other filters to use that mask.
    In the 'Settings' pane of 'Patch Inspector' for the 'Core Image Filter' place the following Core Image Kernel routine code:
    A Core Image kernel routine
    Alpha to Mask White Opaque, Black Transparent
    kernel vec4 alphaToBlackWhite(sampler image)
    vec4 pixelValue = sample(image, samplerCoord(image)); // Get a pixel
              unpremultiply(pixelValue);
              pixelValue.r = pixelValue.a; // Red channel
              pixelValue.g = pixelValue.a; // Green channel
              pixelValue.b = pixelValue.a; // Blue channel
               pixelValue.a = 1.0; // Alpha Channel make Opaque
              return premultiply(pixelValue);
    Alternatively you could rewrite the above Kernel, more details on writing Core Image Kernels is in the developer documentation 'Image Tutorial: Writing Kernels'
    Hope this helps,
    Neil.

  • Quartz Composer effects render blank white video - confused re Core Image

    I've tried the Quartz Composer effects in iMovie 6 but they preview as blank white video and when I apply the effect they render as blank white video.
    Here's my video config:
    Chipset Model: ATY,RADEON
    Type: Display
    Bus: AGP
    Slot: SLOT-A
    VRAM (Total): 32 MB
    Vendor: ATI (0x1002)
    Device ID: 0x5144
    Revision ID: 0x0000
    ROM Revision: 113-74901-224
    Displays:
    Acer AL1912:
    Resolution: 1152 x 870 @ 75 Hz
    Depth: 32-bit Color
    Core Image: Not Supported
    Main Display: Yes
    Mirror: Off
    Online: Yes
    Quartz Extreme: Supported
    After reading this page:
    http://www.apple.com/support/imovie/hottips/
    I see that the Quartz Composer effects are supported only for Core Image supported video cards. I think that means I'm out of luck. It seems odd that the effects still attempt to render and be applied even if my system doesn't support them. Is something wrong with my installation, or is this expected behavior?
    I've seen statements here on the discussions that Quartz Extreme should enable effects like the ripple when opening or closing Dashboard Widgets. My card does support Quartz Extreme but I do not see the ripples. I'm guessing that it's actually Core Image that produces those effects and that's why I don't see them. Is that a correct guess?
    I guess I'm confused over the difference between Quartz Extreme and Core Image.
    Thanks for clearing up my confusion...

    Quartz Extreme, as I understand it, is used by OS X for drawing windows
    That is true. Quartz Extreme is a special, hardware accelerated instance of Quartz. Quartz is OS X's native drawing environment. When Quartz Extreme is not supported, Quartz will be used instead.
    Quartz Composer is something else that builds on Quartz. It appears it requires Core Image. Core Image is a set of graphics routines that allow image manipulation (if you have the developer package installed, you can also find an application called 'Quartz Composer' that you can use to define effects, screensavers etc).
    Core Image also intents to leverage your GPU. Apple's Documentation alleges that if there is no GPU available it will use the CPU instead. Theoretically, your Mac should support Core Image. Yet...
    From Dennis' System specs:
    Core Image: Not Supported
    This may be the reason why you can't use these effects in iMovie. Because of shortcomings in iMovie's plug-in API, the plug-ins may still show up in the f/x panel - they simply will not function when selected.
    Perhaps a later version of OS X enables CoreImage on all Macs?
    Hope this helps,

  • I am having trouble with iTunes (possible Quartz Composer Visualizer problem) but have no idea how to fix it.

    I tried to use my iTunes but the icon didn't show up and instead I get a folder. The folder is titled TunesApp and in it is another folder called Contents. Contents contains: _CodeSignature, Frameworks, Info.plist, MacOS, PkgInfo, Resources, and version.plist. In the folder MacOS is my iTunes and I can use it, but I get this message:

    I can only use my iTunes as long as I keep the message open. When I close the message it tells me: "Closing this window will terminate the running processes: login, bash, iTunes." I have no idea what is going on with it as it was working not too long ago. I do not think I updated it recently but I could be wrong. Any help would be much appreciated.

    Sounds like your computer is having additional issues.  I suggest taking it to your nearest Apple Store.

  • Keynote and Quartz Composer

    I am fairly new to Quartz Composer, that being said I have built several animations that I want to add to Keynote presentations, but everytime I try to add them into Keynote they only last :30 sec.  I have tried exporting as a .mov file and each time I do I am prompted to give the file an end time, I have tried several different times, and yet Keynote still gives it a :30 sec runtime.  I have looked at the exported file in Quicktime and it also says the file is only :30 sec.  I have been searching forums for some time now with no luck, but I have found that I am not the only one with this problem.
    How can I get the QC file to last longer than :30 sec?  Any help in this area would be greatly appreciated as this is really starting to wear on me.  Thanks.

    Welcome to the discussions, agentdavo.
    I don't think it is. I tried the same thing (to try to get around QuickTime's 3 second limitation) and Keynote isn't allowing access to the video hardware.

  • How can I use multiple cameras in Quartz Composer?

    Good morning, all. This is a quartz composer question, but I can't see a quartz-composer specific forum to ask it...
    As part of a school project at ACAD we are building a rig to record the output from three video cameras to build a panoramic video. I have played with Quartz Composer to do the melding of videos recorded with this setup into a single image, and it worked very well.
    However, to do so live is the intention for this project as well, so we can build the composite video for recording (the timing of three different cameras is a bit awkward) as well as line up the cameras without having to do so separately.
    In Quartz Composer, however, the video-in plugin only reads the camera model number, not the unique GUID as seen in the System Profiler, so three identical cameras will not be read properly... you can only choose the model number, not the specific id of the camera.
    Is this a bug in Quartz Composer? Is there some top-secret plugin that is hiding somewhere that will allow you to choose the individual camera id's as seen in the system profiler? (Cameras tested have been firewire handycams streamed live, and usb cameras. identical model numbers can't be chosen as individual cameras properly)
    Thanks muchly, and please shuffle this question to the proper forum as necessary.

    I am working on a project where I need the same functionality. But even though I'm using different webcams, and can clearly select them in the menu, still only one camera works at a time. Even if I run two separate patches, with two different camera inputs, only one of them works.
    If you find any solution to this problem, I would really appreciate if you could share it.

  • How do I install Quartz Composer on my imac 7-27"??

    I am trying to get into Quartz Composer and I am very confsed since imac 7-27' doesn't come with a cd-instal anymore. I tried to do online, installing xcode 4 from the apple site, but at some point it says that i never used itunes store and ask me for my billing details...it's confusing since Quartz Composer is a free aplication. Any ideas on how to dwonload this. On SnowLeopard you can do it through your instal cd, But how to do it in Lion????
    Much appreciated!!

    You need to provide billing information to DL from the App Store, whether or not you buy anything. That's the only way to get anything, including free stuff, from the App Store.

  • Quartz Composer files presented as QT movies

    Dear All,
    I have discovered the Quartz Composer in the Dev tools and have been having great fun using it. However, when I insert the QTZ file into keynote (i am using keynote 3 and tiger 10.4.4) it plays as a quicktime file with reduced resolution.. very annoying. Is there anyway of rectifying this? I've also tried linking to the qtz file as a hyperlink but as you know keynote won't let me.
    Any help would be appreciated!
    Conor

    Are you setting Keynote to enlarge the slideshow to fill the screen? If so, then that may be why your .qtz files look blocky around the edges. Try turning that option off to see if it enhances their look any.
    EDIT:
    Just tried that and it doesn't work like that. It appears that if you want it to show up looking as good in Keynote as it does in Quartz Composer, then you'll have to use it at the same resolution it's used in Quartz Composer. Enlarging in Keynote will make it blocky, enlarging in QTZC then dropping it into Keynote will make it show properly.

    Quartz Composer wasn't built correctly, it needs you to install Xcode into /Developer (the default). If you install it anywhere else, it'll crash with the log you mention.
    You can fix it with the following command (in Terminal)
    installnametool -rpath /Developer/Library/PrivateFrameworks "<your install path>/Library/PrivateFrameworks" "<your install path>/Applications/Quartz Composer.app/Contents/MacOS/Quartz Composer"
    In Nathan's case, <your install path> is "/Users/nathanbriggs/Developer".

  • Where's the best place to find Quartz Composer experts? (looking for a developer)

    I'm looking for a Quartz Composer developer who is 1) interested in working with an artist and 2) can give me a quote for a specific project I am developing.

    Apple hosts a bunch of mailing lists, one of which is for Quartz Composer devs. I read the list occasionally but have never really had the time to become proficient with QC.
    Start here for general info about Apple's mailing lists:   http://lists.apple.com/
    Then click the "Lists hosted on this site" link to see all the various lists. You'll have to subscribe to quartzcomposer-dev in order to post your questions to the list.
    The list is intended for technical discussions related to development and not really for job solicitation. But the usual folks on the list seem relatively friendly for the most part so I expect if you asked nicely and took any negotiations off-line that you wouldn't receive any flak.

  • Quartz Composer not installing from .pkg on OSX 10.4 - help?

    i don't know what's going on, but for some reason, the Quartz Composer app is not installing when i run the DeveloperTools.pkg
    can anyone offer any advice/assistance or similar experience?
    thanks

    Welcome to Apple Discussions, magneticpitch!
    I can't help you with your question, but I'd like to make a suggestion about using Discussions. In general, it is best to ask your question in only one forum at a time. That way all the answers are in one place, and it is easier for people trying to help to see what has already been suggested. If after a few days, you haven't gotten help in the one place you asked, it is appropriate to ask in another forum.
    Good luck.

  • Quicktime movie chapters in Quartz composer

    Hi,
    I am working on my diploma presentation in Quartz composer on Snow Leopard. It also includes Quicktime movies with chapters that I want to skip to via the Apple Remote (or some other input device). But how can I address these chapters? Is there a way to work with them directly or do I have to do some kind of workaround. I'd be happy to get some hints.
    Thanks a lot,
    Johannes

    check the example code archives. i'm sure i've seen a listing for code that extracts audio from video files....

  • Screensaver crashing when made with Quartz Composer using Asynchronous Mode?

    Hi all, I made a screensaver using video in Quartz Composer but the playback was choppy. I went into settings and used Asynchronous Mode, which sorted this out. It was running fine at first. Runs well in viewer and runs when I select test screensaver. I powered the mac up this morning and any of the screensavers using Asynchronous Mode they start for a second and then the screensaver stops suddenly. Again they work fine whilst test screensaver button is used and in the QC viewer but suddenly not when I use hot corners or when the Screensaver activates???
    Any help would be much appreciated.
    Thank you

    I downloaded his pre-built version and fiddled with it a bit, putting in a .mov file. The saver crashed System Prefs. Discovered that the quartz composition would only open in QT7, not QTX. I tried a quartz composition that did not have a movie in it, and that worked as a screen saver. I tried the movie saver, replaced the movie with one that did open in QTX, which would work in the Finder and QuickLook, although it ran only in QT7 (as do all my old qtz compostions), but it still crashed System Prefs. Unfortunately I haven't installed Developer Tools for Snow Leopard, so don't know if you could get it to work using the latest iteration of Quartz Composer and rebuilding the composition there--don't even know if there is a new Quartz Composer.
    I suspect there is a problem between 32bit and 64bit things, although exactly what that might be I don't know, since the straight qtz compositions, without a movie, seem to work in screen saver mode.
    Using the QT7 only movie produced a slightly different crash report than using the QTX compatible movie. I have seen other reports of non-Apple screen savers that will not run in Snow Leopard, with the statement that the savers must be re-compiled to work in 64bit. My quess is that really simple quartz compositions use the quartz engine available in Snow Leopard, and thus even though built with a 32bit Quartz Composer do run as 64bit, by calling only Snow Leopard functions, and thus will work, but that the movie saver has something inherently 32bit in it and so causes a conflict.

    Anyone as an idea ?

    The MP3 container has a few different brand codecs it can use. You might need to choose a different format for exporting from Audition. I would highly recommend AAC so you can get high quality and compress a production version from that later.
    I guess the version numbers are strangely different between platforms. Either way it's a common problem for people bringing media into Flash because it's not widely known that Flash requires Quicktime for some of it.
