Evaluation and Comparison of Denoising Method: A Critical Review

Kiran Kumari, Dr. Sadhnak. Mishra

Image denoising is a major area of research due to the need of clear images in the field of simple photography, medical image recognition, Human Shape digitization etc. There are several process has been applied when we will work with images like receiving, transforming, coding and decoding. So the chances of noise to be inserted in the real images are high. Our motivation of this paper is to study and highlight the approaches which has been discussed and analyzed earlier. Based on our study we will suggest some better methodology with the loop area where we can apply some method for better noise reduction. Our analysis shows several loop areas where the work will be done in future for better denoising. We also discuss support vector machine(SVM), Partial differential equation(PDE), wavelet based denoising techniques with their flaws and merit and find some future insights also.
