Image Contrast Enhancement Methods

Contrast stretching

Contrast stretching

One of the simplest piecewise linear functions is a contrast-stretching transformation. Low-contrast images can result from poor illumination, lack of dynamic range in the imaging sensor, or even wrong setting of a lens aperture...

Histogram equalization

Histogram equalization

This method usually increases the global contrast of images, especially when the usable data of the image is represented by close contrast values. Through this adjustment, the intensities can be better distributed on the...

MATLAB Classes

MATLAB Classes

There are many different data types, or classes, that you can work with in the MATLAB® software. You can build matrices and arrays of floating-point and integer data, characters and strings, and logical true...

Contrast (Images)

Contrast (Images)

Contrast is the difference in visual properties that makes an object (or its representation in an image) distinguishable from other objects and the background. In visual perception of the real world, contrast is determined...
