find out the image filter response... [3 Articles]
g394...@ym.edu.tw - Jan 9 2007
Hi all!
I am try to find out the low-pass filter cut-off frequency.
I input an impluse to filter,then got the impulse response.
But,I have a problem about the impulse size.

... video processing DV format
Martin Halvorsen - Dec 22 2006
Hi all,
I have a video recordered with a digital video. I won't compress the video
any more than it's already compressed in the DV format. About 15 min of film
is up to 1.7 GB... Impulse Noise and Edges [7 Articles]

Hi,
Iam trying to perform diffusion filter to remove the noise. But my way is I need to select only the corrupted pixels based on some thresholding and diffuse only those ... optimizing difference of two frames

how can i minimize the pixel-by-pixel difference of two frames (video) using gradient descent? is levenberg marquardt better? help
... YUV sequences
praveenkumar yethapu - Oct 9 2006
Hi all,
I am posting a message for the first time... eventhough i am a member from many days.
I am looking for YUV sequences (YUV420, YUV422 etc.) Where can we get t... Problem of image-processing flow on DM642
Vict...@itri.org.tw - Oct 2 2006
Hello,
I'm using DM642 to process video.
However, I found that the frames were captured as YUV422 format by the chip on my DM642 EVM.
Then the frames were transformed to b... Re: Re[2]: Fast Convolution

Ah after some more research I think they may use MMX
Now I just have to learn how to use it as well.
Thanks alot for the help.

Hi
I have previosly been using a image processing library called Imaq vision.
I am now wiriting my own functions.
In Imaq there is a convolution function that takes any size... empty for-loop vs. performance

Hello,
I've written an image-processing function which is called by another image-capturing function on dm642.
However, even if the image-processing function comprises only a...
