IMAGE_COMPONENTS, a MATLAB library which seeks to count and label the connected nonzero/nonblack components in an image or integer vector, matrix or 3D block.

IMAGE_COMPONENTS is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
IMAGE_CONTRAST, a MATLAB program which applies image processing techniques to increase the contrast in an image.
IMAGE_DECIMATE, a MATLAB library which compresses an image by dropping the even rows and columns of data.
IMAGE_DENOISE, a MATLAB program which applies image processing techniques to remove noise from an image.
IMAGE_DIFFUSE, a MATLAB library which uses diffusion to smooth out an image.
IMAGE_DOUBLE, a MATLAB library which doubles the height and width of an image by repeating each row and column.
IMAGE_EDGE, a MATLAB library which demonstrates a simple procedure for edge detection in images.
IMAGE_MATCH_GENETIC, a MATLAB program which tries to match a 256x256 JPEG image by blending 32 colored rectangles, using ideas from genetic algorithms, based on an example by Nick Berry.
IMAGE_NOISE, MATLAB programs which add noise to an image.
IMAGE_QUANTIZATION, a MATLAB library which demonstrates how the KMEANS algorithm can be used to reduce the number of colors or shades of gray in an image.
IMAGE_RGB_TO_GRAY, a MATLAB function which creates a grayscale version of an RGB image.
IMAGE_THRESHOLD, a MATLAB library which creates a black and white version of a grayscale image by specifying a single threshold value; pixels below this value become black, and above this value they are white.
REGION, a FORTRAN90 library which reads 3D MRI voxel data, and groups the voxels into connected regions;
