The aim of image enhancement is to improve the perception of information in images for human viewers, or to provide better input for other automated image processing techniques. There is no general theory for determining what good image enhancement is when it comes to human perception. However, when image enhancement techniques are used as pre-processing tools for other image processing techniques, then quantitative measures can determine which techniques are most appropriate. Here we are proposing some enhancement algorithms based on spatial domain for better image analysis in medical field.
