Abstract : Image Enhancement plays a vital role in image processing in order to make image more usable. Usually, the
image captured from camera are dull in contrast. So, to equalize and enhance the contrast in the image Histogram
equalization (HE) method is widely used. But this method results in the change of brightness of image due to flattening of
the original histogram. Thus, it is rarely utilized for dull contrast and long distance captured images. An extension of HE
algorithm along with edge enhancement to overcome the drawback of HE is proposed in this paper. This algorithm uses HE
algorithms such as Global histogram equalization (GHE) and Dynamic histogram equalization (DHE) along with edge
enhancement using low pass filter implementation and laplacian filtering using Zedboard FPGA. This algorithm preserves
the brightness of image significantly as compared to typical Histogram Equalized image, it also enhances the contrast and
edges in the image.
