Image Processing Toolbox Release Notes

New Image Enhancement Methods

The toolbox includes two new image enhancement functions: adapthisteq and decorrstretch.

The adapthisteq function performs contrast-limited adaptive histogram equalization (CLAHE). This function uses a contrast-enhancement method that works significantly better than regular histogram equalization for most images.

The decorrstretch function performs a decorrelation stretch on truecolor images, or images with multiple color or spectral bands. Decorrelation stretch is a technique used to enhance, or stretch, the color differences in an image. This function can be used, for example, to aid visual interpretation when two or more bands are significantly correlated.
