Low-light image enhancement plays an essential role in many applications of image processing. According to our observations, although many methods have been proposed to solve this problem, the obtained enhanced image may be lost in detail. This paper presents a new approach to solve the above problem.

Recently, the innovative vein finder system has been studied extensively and has many practical uses in healthcare and security. Developing a better vein finder system often relies on image processing procedures which help to enhance the vein images. Conventional image processing procedures as median filtering and adaptive histogram equalization have shown benefit in enhancing vein patterns. However, in some cases when there are hairs present in the images, most of these procedures are less effective in removing noises from hairs.

The S component is enhanced by histogram equalization while the H component does not change to avoid degradation color balance between the HSI components. Finally the enhanced S and I together with H are converted back to its original color system. The new approach gives Brightness enhancement more than 20% when was applied on different type of images and tested the performance.

The developed technique involves contrast enhancement using sequentially iterative smoothing filters, histogram equalization, and simultaneous application of two types of edge detection processes namely, maximum-difference edge detection [3] and Canny’s edge detection [4]. The post processed image is combined with the original image to accentuate the edges while eliminating noise. Smoothing is implemented because of its effect to reduce specific types of noise signals in the digitized image.
