Oscillating amplidude waveform to be smoothed out, and calculate frequency of difference of original waveform

a steep impulse of oscillating amplitude, i need to smooth out the waveform and calculate the frequency of difference of original waveform and smoothed waveform how to do this?
i have tried to do with calculating moving average of the data points.
i have attached the data points here with.

Hello,
I was not able to open the MS Word DOC attached to your post, so I am not exactly clear what your dataset looks like. When you say you have an oscillating input that is an impulse, do you mean that the waveform contains discrete jumps? If so how would you like to smooth the waveform?
Can you please post two graphs, or two sets of datapoints which describe your input and output? By looking at exactly how a specific input should be translated to a specific output we should be able to give you a much more specific answer.

HOW TO- Smooth out your animation jittering and tearing

I've found a couple of workarounds that will smooth out your animations. There are JVM arguments that you can pass that allow you to set the scenegraph animation framerate and vsync properties. Increasing the framerate pulse and settig vsync to true can smooth out most of the animation jitters we're experiencing. The downside is that this is going to cost you some CPU time.
-Dcom.sun.scenario.animation.vsync=true -Dcom.sun.scenario.animation.pulse=500I also saw that the JavaFX team has made solving these animation issues a top priority for the next release.

Nah, forget it. This logo needs to be redrawn from scratch.

How to smooth out discontinuous spacial distribution gradients

Hi all.
I'm controlling a linear motion device, and need to generate displacement paths for it to obey. What I'd like is to smooth out the 'sharp edges' in my profile data (for example, at points where it may go from a slow forward motion to a faster forward motion). Technically, this is removing the discontinuities in the spacial distribution differential, but in other words all I need to do is "smooth my data".
I've mimicked what I want to achieve by putting some hand-created numbers into this graph -->
The yellow line is my original profile data. You can see that I'll be moving the device from position 45 at time 0 to position 52 at time 5 and finally position 53 at time 9. This is fine, but I'd like to smooth out the motion a bit and avoid that nasty elbow at time=5 a bit.
The blue line is what I'd like. A smooth run from position 46 at time 0 to position 53 at 9 seconds, that preserves the velocities (gradients of the profile line) at the beginning and end. The reason for this is that the motor will arrive at position 46 (time 0) at the velocity inferred by the first gradient, and will continue beyond position 53 after time=9 at the speed inferred by the end gradient. Therefore I must not change the gradients of the line at the beginning and end.
I've tried using the many Signal Filtering techniques LabVIEW has available, but I've found that they create problems:
1. They don't preserve the beginning and end gradients, and
2. They tend not to like the very few sample points I have here. (If I interpolote the yellow line to create intermediate points, the filtering works better, but still suffers from point 1)
I've tried using the B-Spline curve fit, but that seems also not to respect the gradients.
I've tried the cubic spline fit, but that doesn't return the extra points I need to create the blue curve the way I've shown here.
Does anyone have any advice? I thought this would be simple, but I'm a bit stuck now but I suspect that there'll be someone out there that's had to do this too.Naively I expected there to be a simple function called "Smooth Data", but clealy not.
Many thanks in advance for any responses received.

In my copy of Haliday Resnick and Walker there was a note that talked about Einstein and "working in divine issolation" where he was not distracted by others telling what was leagl and what wasn't. I recall that note when I propose idea like the following that some math type will tell me has not physical meaning and dismiss it off-hand. But since I don't limit myself to what is allowed or legal...
See this thread starting a post #5.
Summary:
CC's best attempt at smoothing the curve was shown in this plot.
Using my non-legal technique, I got these results.
I a nutshell:
When yo ufilter you loose data at the front and back-end with the number of points of data loss being determined by the order of the filer. By first pre-pending and appending the same data set reflected about the first and last point, we trick math into telling us what it woudl refuse to tell us otherwise.
maybe this will help you,

How do you smooth out lines in Photoshop CS5

I have some black and white line art drawings. The lines are not smooth and sharp, and instead have tiny jagged edges. I tried using the smudge tool, and that does smooth out the lines but it also makes the lines a little sloppy. That's probably how the Smudge Tool got its name. Is there a way to use this incredible software to create smooth lines? I've learned how to create paths, but I can't figure out how to use the paths to change the line art. Maybe this is what I'm looking for?

-Noel
If I understand your question correctly then the answer is yes.
You can create an arbitrary path whose shape, open or closed, can remain editable throughout your session and it can be duplicated if needed. That path can then be stroked with a pixel painting or editing tool. Lets say you create a new layer and stroke a path with a colored brush. You can then add a style to that layer, move that same path and add a different stroke on a second layer and then duplicate the path, move it and edit its shape and then do yet another stroke and style on a third layer. This is what I've done in the image below showing the stroke & styled paths as well as the vector path in the bottom path.
Once a path has been stroked to a layer and has had a layer style applied it is only editable as pixels, but the shape remains as a path which can re restroked or moved or reshaped so flexibility is high.

Punch in/out and crossfades

I'm really surprised at how lousy the documentation is for Garageband '08. I'd just like to learn how to:
1 - Punch in on a track
2 - Smooth out the result of the punch-in (I belive that's called crossfading, correct)
Any help would be much appreciated.
Thanks,
Scott

I still haven't exhausted all the possibilities, but to add to these comments ... if you can't play along with the original track to "get ready" for the punch-in .... then I wouldn't really call it a punch in, and it's not the ideal solution, at least musically.
What was suggested to me elsewhere is to split the track where you'd like the punch in to be (which isn't ideal if it's in the middle of a phrase) and then delete what you'd like replaced. Then duplicate the track. Then you can record on the duplicated track, playing along with the original, without erasing it.
The part that I'm still not 100% clear on is how to combine the two tracks SEEMLESSLY (meaning with NO evidence of the edit). The first reply I got to this post talked about "curves", but I still haven't figured out if there's a simple way to do this.
There's got to be a decent way to do this ... if not, I'm going to have to learn ProTools LE.

How to smooth out zooming/scrolling image that jerks (CS4)?

Hi guys/girls,
Is there any way that i can smooth out images that zoom in/out with normal classic tween. they are so jittery it looks terrible. I even have a little bit of easing and frames per second set to 30.
any info much appreciated!
Jeff

Hi flashfever,
thanks for responding. can you elaborate on how i can use that? is it AS for the 1st frame or on the movie clip itself? etc
in this case, i have the image fading in and enlarging from 70% to 100% in the same tween. its very jerky.
thanks for your help so far!

How do you smooth out a coat?

Having a hell of a time figuring out how to smooth out the arm of this coat. thanks

One technique I like, which fits in with the frequency separation thing JJ talks about is this:
1. Switch to 16 bits/channel and a linear color profile.
2. Mask so just the arm is showing. The Quick Select Tool works well for this.
3. Refine Edge to get it into a new layer
4. Do a Filter - Other - High Pass, choose a radius that shows the wrinkles, but not too large.
5. Image - Adjust - Invert.
6. Change the blending mode to Overlay and watch the tight wrinkles magically get smoothed out.
To take it a bit further...
7. Flatten the above.
8. Mask the arm again, Refine Edge to make it a new layer.
9. Filter - Noise - Median until it is very smooth.
10. Hide the unnaturally smooth looking parts with a dark color in the mask.
Something like this isn't too difficult to achieve... Took me longer to write about it.

Why does jitter graph smooth out when we add Codec to IP SLA

We use NetQos to monitor jitter, delay and MOS. On a single tunnel, we have three IPSLA measurements, one with the defaults, one with ToS=184, and one with ToS=184 plus Codec=g711alaw. The bona fide data traversing the link is time sensitive, but not VoIP. I understand MOS can only be measured when applying a Codec, but that shouldn't change the jitter and delay statistics, yet it does. The jitter graph on the IPSLA with Codec is much less voilatile than the jitter graph with just ToS. In other words, when the Codec is applied to the IPSLA, the graph smooths out. Anyone have a good explanation? And should I use the MoS as a rough guide, even if I'm not flowing VoIP? jc

I have two scripts that might be some good inspiration. One reads virtual ECMP bundle details from EEM envvars while the other reads a config of ports from a file on flash (the format is listed in the script header).

MacBook Pro Photoshop CS4 not smooth zooming and fine lines are broken

I got a new MBP 15" about a month ago and am also running Win XP via bootcamp. On the Windows side Photoshop CS4 will not smooth zoom and if I zoom out, fine lines are broken apart and only partially show. When I go into the performance preferences enable opengl is checked and under advanced, advanced drawing is checked, but the use for image display is grayed out no matter what I do.
On the Mac side it works fine using either the 9400 or 9600 chipsets so considering Windows uses the 9600M GT which is the discrete one, it should work.
There's no driver updates here on Apple.com and Nvidia.com says there is an update available, but when it tries to install it says the hardware isn't supported... even though on the screen before it says it is.
Any suggestions would be much appreciated

Anybody have any suggestions?

Notification center "grayed out" and will not open. Any ideas on how to fix?

I purchased Mountain Lion this morning and updated from Lion. Everything worked smoothly. As I was looking through various new features, I see that Notification Center is "grayed out" and won't let me open it.
When I go to System Settings, Notifications is there, and will let me go in and make changes. There's no indications that it shouldn't work.
Mid-2007 iMac, 4GB RAM, 2.8ghz Extreme.
Any ideas?
Thanks!

Little late to the party on this, but I was having the same issue. My notification center icon was greyed out and nothing happened when I clicked on it.
Here is the fix that worked for me.
Found the following folder:
~/Library/Application Support/NotificationCenter
Inside it were two files. Presumably there should only be one.
The first was
XXXXXX.db
Where "X" was a series of numbers.
The second was
XXXXXX.corrupt
I deleted the file with the corrupt extension and emptied the trash. Then went to activity monitor and force quite the Notification Center process. This caused it to restart and everything was back to normal.
Hope that helps.

Smoothing out a low res raster signature

I have a really low res raster image of a signature and I've been trying live trace but it keeps making it look unrealistic. Is there anyway to simply smooth out the jaggedness produced by the low resolution while keeping the shape?

Forget autotracing. Redraw the signature as proper vector paths. An autotracing program has neither human intelligence regarding legibility or readability, nor any sense of human aesthetics. Plus, tracing around a signature is an excellent exercise for someone learning to draw Bezier curves.
Would that be DL650 or DL1000?

After effects automaticly smooths out animation paths between key frames?

when moving somthing how do i disable the feature when AE automaticly smoothes out the path between key frames? the image shows three key frames which i want the text to come down and then to go right with a right angle as a path, not the curved line they have generated!
Thanks for your time

Help me smooth out my lighting.

What Setting do I need to change to smooth out the edges of my lighting in this shot, and get rid of those hard edges?

I presume you're talking about the banding in the transition from dark gray to black. There's only so much you can do, because there are so few values of gray being spread across a much higher number of pixels.
The first thing to do: work in 32 bits. It'll help even if you eventually render out to an 8 or 10-bit codec.

Smoothing out "slider" or "dolly" shots

Looking for some help smoothing out camera slider shots. They are "side to side"( as opposed to straight in) and show some vibration during the move. I have tried reducing the vibration in Motion but the analysis constricts the video on the X axis and bunches the video to one side. This leaves a blank/ black canvas showing on half of the project. Any help with preserving the "move" while reducing the vibration/ camera shake?
thanks in advance...

If you're using the Stabilize behavior, restrict the direction to the vertical only.

Taking out and replacing memory and hard drive.

Hey so I want to get a macbook pro 13 in. and I want to upgrade it by putting in more memory and a better hard drive, but I want to buy parts from a different site because it is so much cheaper. Is it easy to take out and replace the memory and hard drive of a macbook pro?

Just make sure the RAM you're buying is brand name and match the specs of your macbook.
Getting cheaper RAM modules sometimes cause issues with the way your Macbook peforms. Learned that lesson when I decided to buy Kingston Value RAM. Had nothing but trouble.
Stick with brands like Crucial ( which I use ), Corsair, Mushkin, Kingston (non value) and from OWC.
As for the hard drive, stay away from Western Digital Blue edition, some macbooks have issues with them.
Also make sure you buy an external USB enclosure so you can clone your drive before you intall it and install your old drive in the USB enclosure and use it as your backup drive.
If you're technically capable, it quite easy swapping out the RAM and Hard Drive.
Do the clone first before you do anything else. That way, when you're done the clone, you just have to open up your macbook once to do the swap.
Good luck and hope everything goes smoothly for you.
Post back if you need a hand or have any questions.
