Compare two jpeg's taken from ip camera
Hi folks,
I've got an IP camera, and I need to take two photos and compare them, and then my program must return if there's something different on the image. Taking the photos is not a problem, using an activex control with the camera library I can use a function that writes a jpeg image to the disk. The real problem is to compare those images. I tried to subtract them, but since the sensor is a CMOS, there's a lot of noise, and even if i take two photos without moving anything, when i subtract the pictures it is not empty (black).Then I tried using Vision Assistent or the Golden Template, but I could not use them, because of two problems:
- first, most of the functions on Vision Assistent can only process 8 bit binary images. Does someone know how to convert a jpeg to this format?
- second, when i tried to open images to use the IMAQ functions on my own vi, i used the IMAQ image.ctl and typed the path to the pictures, and connected them to the functions, but everytime i run thid kind of VI, it returns an error saying that the file is not an image.
If you know how to solve one of these issues, or if you think of another method to compare the jpeg's, please let me know!
Regards,
Vitor
Solved!
Go to Solution.
I forgot to post some of the images i need to compare:
Image 1 Image 2 Image 1 - Image 2
When i compare image 1 and image 2, my VI must return nothing, but if the cup isn't there on image 2, it must return a warning.
What i did was to deploy the images in 2D arrays, subtract them, and if the result was different from 0 the VI returns the warning, but even when the images are "equal", the subtraction is different from zero.
Any ideas?

When I pushed a button, this pop-up window has to appear. There will be a slide control and a picture from a camera in this window. Is it possible to make appear this windows while main VI Interface continue to run ? How can I do this ? Thank you for your answers.
Cyril.Here you go. This is simple example. Maybe not the best way, I am just
beginner in LV and still not comfortable with data flow that much. I prefer
events, so I would change this to use Event Structures.
When you click on OK button on SliderMain, it opens Slider.vi. Now both
windows are open and you can interact with both. Now if you click on OK
again with Slider.vi open, you run into problems. Only thing I did was
change VI properties of slider.vi, mainly window appearance.

Warranty on the issue of purple spot in images taken from rear camera?
My iPhone 5 have purple spot in images taken from rear camera. I just noticed the issue in my phone today.
I researched online and some people also have the same issue and have their phone replaced in Apple shops.
I don't have any receipt or store warranty card since it was just given to me as a gift in the Philippines last April 2013, I checked the warranty coverage status (https://selfsolve.apple.com/agreementWarrantyDynamic.do) and it still has repair and service coverage.
Im now here in Dubai, and my question is that will Apple Premium Reseller shops here in Dubai honor the said warranty and have my iPhone repaired or replaced?Im now here in Dubai, and my question is that will Apple Premium Reseller shops here in Dubai honor the said warranty and have my iPhone repaired or replaced?
No.
The warranty for an iPhone purchased from an official source in the Philippines will be honored in the Philippines only. -
I have processed my raw and jpeg files on my iPad using Snapseed . What format are they saved in on the iPad and how do I transfer them back to my pc where I use photoshop elements. Can I use just an ordinary flaws drive with the USB adaptor? Thanks any help would be appreciated.
LynneThe camera connection kit can only be used to import photo/video files form a camera, SD card or USB flash drive. You can't import other types of files. You can't export any type of files using the camera connection kit.

Duplicate photos - I get two everytime I upload from my camera
Hi all,
I've seen a variety of posts about duplicate photos in iPhoto and I am a bit confused. We have thousands of photos on our iMac in different user accounts. I know some are duplicates as various family members want their "copy" in their account. I would think we could put them in a "Shared" folder or some such but don't know how as yet. Anyway, the main question is, when I upload photos from my digital camera I get to files on my iMac. One is a large file and the other is like a 320x640. I assume iPhoto is generating a thumbnail and a full size as two separate files? Why???? Does it need both to function? I deleted some of the smaller files and then found they don't show up in the events folder anymore. Anyway, I need help managing my photos for sure. Thanks for the help and patience with a new iMac user.Welcome to the Apple Discussions.
I assume iPhoto is generating a thumbnail and a full size as two separate files? Why????
It's the nature of the beast. The thumbnail file is an essential part of the library for viewing as smaller sizes than full size. By deleting them you've committed the cardinal sin of iPhoto - modifying the contents of the iPhoto Library package from the package.
You may be able to rebuild the thumbnail file by launching iPhoto with the Command+Option keys depressed to rebuild the library. Select all options.

I would like to import two different cf cards from two different cameras into the same project/folder and have them be in the order of the times they were taken, any ideas on how to do this?
Just import them normally and sort the project by date. They will fall into place. If you tried this and it isn;t happening then make sure the data and times on the two cameras are identical and make sure you are sorting by date and time and nothing else.

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?
I think that may be a consequence of the email provider she is using. Some services (AOL is one example) inspect and modify email attachments, particularly photos, resulting in reduced resolution compared to the email that was sent.
The iPod does not do this. The resolution of the picture in the email she receives will be identical to what is imported. -
Raw files from second camera being converted to JPEG first.
I started using two cameras recently. My raw files from the Rebel T2I upload as raw files which is great. But my raw files from the Rebel XS are being converted to JPEG when uploaded. How do I correct this? I want the raw files to upload.
Or the camera is shooting RAWJPG and LR is accidentally hiding the RAW instead of the JPGs, like it did with another camera recently. This can be diagnosed and remedied by enabling the LR setting to treat RAWJPG as separate files.
Or the camera is set to point-to-point instead of mass-storage mode for the USB (or some driver is installed and doing the same thing) and the OS or a Canon codec is converting the files to JPG on the fly as they are read from the camera. This probably can be diagnosed and avoided by using a card-reader and examining the files on the card to make sure they are raw and transferring them with Explorer or Finder to the hard-drive and doing an Add import instead of using LR to do the transfer. -
I can not synchronize the videos taken with my camera from my PC to IPad
Hello everybody, I have a problem, I can not synchronize the videos taken with my camera from my PC to IPad (sorry, in my last question I put iPhone but is iPad )
Are they in a compatible format ? The iPad natively supports (from here)
Video formats supported: H.264 video up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format
If your camera's videos aren't in any of those formats then you will either need to find a third-party app that doesor a PC program that can convert them prior to syncing. If you can get them into your computer's iTunes via File > Add To Library but they don't sync, then have you tried Advanced > Create iPad Version and then syncing those versions ? -
Is it possible to have two USB drives for the IPad? I want to bring RAW files from my camera through the IPad and out to an external hard drive. One of my cameras has an SD card but the other one doesn't have a card that would fit in any of the camera devices I've seen on line. Realted to this, I bought the IPad camera accessory. Can I put the SD card in the device and also hook the external hard drive to the USB port of the accessory and download from the camera to the hard drive? Can I put Lightroom or the Nikon photo editing software on the IPad? Right now I carry a PC laptop and external hard drives with me on wildernes trips. Internet and WiFi are not available. Because I shoot so many photos and they're in RAW I need to download from the camera to the external drive because I run out of memory on the PC (and it has much more memory than the IPad). I have Nikon NX software and lightroom on my PC. I'd love to be able to reduce the weight I carry by using the IPad to edit my photos each night while on trips. Is this possible and how would I do it? I'd appreciate any guidance.
No, the camera connection kit only supports the copying of photos and videos to the Photos app, it doesn't support copying content off the iPad. For your second camera instead of the SD reader part of the kit, does the iPad to camera cable not work with it for direct transfer to the iPad ?
For Lightroom and Nikon software again no - you can only install apps that are available in the iTunes app store on your computer and the App Store app on the iPad, 'normal' PC and Mac (OS X) software are not compatible with the iPad (iOS). There are some apps that perform fairly basic editing functions that are available in the store, but nothing as sophisticated as, for example, Lightroom. -
How do I add photos to my camera roll that were not taken one my iPad? I have iMported photos from my camera to my iPad. Theses photos are in the imported photo album.

Consider using sshfs to mount your Pi from your Linux boxes. It's much easier to configure and manage than samba. It sounds like you already have your Windows machines mounting your Pi so Samba is doing its job in that respect.
More info on sshfs in the Wiki: https://wiki.archlinux.org/index.php/Sshfs
To help get you off the dime, here's a modified line from my fstab that I use to mount my Pi with:
gav@PI:/mnt/backup /mnt/rpi/backup fuse.sshfs rw,relatime,user_id=0,group_id=0,allow_other 0 0
Subsitute my mount points with yours.
For a password-less mount:
ssh-copy-id gav@PI
after you've set up ssh and generated some keys on your client box.
