Color Image Contrast Enhancement in MATLAB

Histogram equalization seeks to flatten the image histogram so that the intensities are more or less equiprobable in being encountered in the image.

I have a greyscale image which has pixel values ranging from 1.000 to 1.003. I would like to increase the contrast between the different pixels.

First, convert the RGB image into HSV format. H and S channels contain the color information while the V channel contains the brightness value ...

Learn how to perform image enhancement in image processing with MATLAB and Image Processing Toolbox. Resources include examples, videos, and documentation.

The Adjust Contrast tool enables you to interactively adjust the contrast and brightness of a displayed grayscale image.

To enhance the contrast of the image, the model uses a Histogram Equalization block with default parameters. The block transforms the normalized luminance ...

Contrast adjustment works by manipulating the display range, or the range of pixel values that map to different display colors.

Adjust image contrast and brightness by using the Adjust Contrast tool or the Window/Level tool. Specify Contrast Adjustment Limits. You can specify the range ... Contrast Enhancement... · Imadjust · Imcontrast
