Design of An Efficient Image Enhancement Algorithms Using Hybrid Technique

Abstract

Fundamental purposeof the image enhancement is to process the image in such a way so as to produce an image that is better in some or the other aspect than the original one for a specific purpose. It makes it easier for human viewers and machines to extract, interpret, and wherever necessary perform further processing on the information contained of the images. Image Enhancement is one of the important requirements in Digital Image Processing which is essential in making an image useful for various applications which can be seen in the various areas of Digital photography, Medicine, Geographic Information System, Industrial Inspection, Law Enforcement etc. Image Enhancement is used to improve the poor visual quality of the images. The proposed method is a hybrid method which is very effective in enhancing the images. Initially, frequency domain analysis is done followed by spatial domain procedures. The performance of the proposed method is assessed on the basis of two parameters i.e. Mean Square Error (MSE) and Peak Signal to noise ratio (PSNR).
