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.

are based on direct manipulation of pixels in an image. ▻ Frequency domain. ▻ based on modifying the Fourier transform of an image.

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 ...
