Image Enhancement and Its Techniques - A Review

Now days applications require various kinds of images as sources of information for interpretation and inspection. Image enhancement is method of applying different alterations to an input image to make the resultant image more pleasing or to provide a better transform presentation for future automated image processing techniques. Many images like medical images, images of satellites, and even real life photographs suffer from poor sharpness and noisy effects. This is essential to enhance the contrast and remove the noise to increase picture standard. One is presenting a review on various image enhancement techniques for sharpening enhancement. However, these techniques are able to bring noticeable changes in the images and sometimes also produces unwanted artifacts in many cases. These problems need to be resolved so that better enhancement may be performed in future work. This paper proposes a new work for enhancement by using artificial intelligence schemes.
