Advanced Image Enhancement Based on Wavelet & Histogram Equalization for Medical Images
Yashu Rajput · IOSR Journal of Electronics and Communication Engineering · 2012
Image enhancement is used to produce high quality pictures like Medical images.As the quality of the image is very much depends on environmental effects like light, weather or equipment that we used to capture the picture, images may loose important information which is required to enhance the quality of an image.So we have many techniques to recover the lost data to improve the quality of the picture .In this paper, we are using non linear enhancement technique to increase the contrast level of an image like wavelet transform and Histogram Equalization.In this experiment we found that this method enhance the contrast level of an image.
