Imfilter

I have used "imfilter" , which is a part of image processing toolbox. If you don't have image processing toolbox, change "imfilter" to "filter2" and the function should work as good. Platforms: Matlab

DIFFUSION_DISTANCE calculate the diffusion distance between matricesdist = diffusion_distance(im1, im2, [sig, dim], threshold, pad_type])[dist, iter] = diffusion_distance(im1, im2) compute the diffusion distancebetween im1 and im2 (histograms).Optionally returns the number of iterations. This... Platforms: Matlab

IMGAUSSIAN filters an 1D, 2D color/greyscale or 3D image with a Gaussian filter.Instead of using a multidimensional Gaussian kernel, it uses the fact that a Gaussian kernel can be separated in 1D kernels.By the default the code uses IMFILTER for the filtering. But also a cache efficient MEX /... Platforms: Matlab

IM-Filter is a daemon for GNU/Linux firewall hosts written in C which is able to analyze and filter the ICQ protocol. The daemon runs in userspace and fetches packets of the ICQ protocol by using the libnetfilter_queue mechanism. IM-Filters main purpose is to run at a gateway, so all... Platforms: *nix

#5237 implements a Gabor filter for image processing. From the comments and through my own use, the implementation seems to have limited freedom, and also the variances are defined in the original x,y instead of the rotated x', y' directions.The code is a modified version based on...

Extracts the edges of a color image without converting it to grayscale.Changes in color are detected even when the grayscale color of two pixels are the same. The edge strength is typically greater or equal to the magnitude obtained by simply filtering a grayscale image.Optionally, the edge... Platforms: Matlab

In short:normshift function- fast and efficient multi-dimensional and multi type, with only zero bound assumption.imshift- designated to be used with images. Capable to shift several images at once, user definable boundaries assumptions.While sirchift is fast and all types and input dimentions... Platforms: Matlab

This function SEPARATEKERNEL will separate ( do decomposition of ) any 2D, 3D or nD kernel into 1D kernels. Of course only a sub-set of Kernels are separable such as a Gaussian Kernel, but it will give approximations for non-separable kernels. Separating a 3D or 5D image filter into 1D filters...

This functions allows the user to apply a function of his choice to all video frames- frame by frame.Consider a case you have a function you're used to apply to single images like imfilter, imresize, imadjust, imcrop etc... (see Matlab Image Processing Toolbox for additional functions), and now... Platforms: Matlab
