In this paper histogram equalization with image interpolation are presented. Histogram equalization is a very important widely used contrast-enhancement technique in image processing. Image enhancement is a means of improvement of an image appearance by increasing luminance of some a distinctive attribute or by decreasing ambiguity between different regions of the image to improve quality. This paper proposes simultaneous interpolation and equalization of digital images. The best performance has been achieved when performing the equalization on interpolated images instead of performing the interpolation on equalized images. Finally, we can say that the proposed techniques achieve better performance compared to other techniques.
