What is image contrast enhancement?

Contrast enhancement involves changing the original values so that more of the available range is used, thereby increasing the contrast between targets and their backgrounds. The key to understanding contrast enhancements is to understand the concept of an image histogram.

What technique can be used to increase contrast enhancement?

Histogram equalization (HE) is a common contrast enhancement technique that is widely used by different imaging applications due to its easiness and rapidity [21]. Basically, equalizing the histogram is achieved through the reallocation of pixel values for a given image.

What is contrast enhancement algorithm?

Contrast enhancement: is defined as the manipulation and redistributing the image pixels in a linear or non-linear fashion to improve the separation of obscured structural variations in pixel intensity into a more visually differentiable structural distribution.
