Introduction. • The principal objective of image enhancement is to process a given image so that the result is more suitable than the original image for a ...

A contrast stretch improves the brightness differences uniformly across the dynamic range of the image, whereas tonal enhancements improve the brightness.

Log Transformations. ➢The Log function has the important characteristic that it compresses the dynamic range of images with large variation in the pixel ...

Spatial domain process on image can be described as g(x, y) = T[f(x, y)]. Where f(x,y) is the input image, g(x,y) is the output image, T is an operator.

Enhancements are used to make easier visual interpretations and understanding of imagery. The advantage of digital imagery allows to manipulate the digital ...

What is image enhancement ? We try to improve an image so that it looks subjectively better! original image enhanced image.

Image enhancement techniques improve the quality of an image as perceived by a human. These techniques are most useful because many ...
