The purpose of our review is to provide relevant researchers with a comprehensive and systematic analysis on image enhancement techniques and give them a ...
Image enhancement techniques are usually applied to remote sensing data to improve the appearance of an image for human visual analysis. The main focus of ...
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.
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 ...
