Abstract :
To control important image´s properties- light intensity and sharpness, and emphasize on image portion, the image equalizer is mandatory. This paper proposes CLP-HE (Cumulative density function, Linear function and Pixel position scheme-based Histogram Equalization) for moving image. The results show that the computation time has been improved. In addition, the appropriated parameters in CLP-HE can be processed to improve image portion quality on the moving image.
