Image Optimization using Wavelet based Approach and Quality Assessment of Compressed Image

In this section proposed an algorithm based on stochastic resonance to enhance the low contrast image. This algorithm is based on thresholding, mean, minimum, maximum and standard deviation only. In this noise is added repeatedly, and also utilize the well known histogram technique of image processing. Easy to implement is an advantage of this proposed algorithm. To verify the utility of this algorithm, this is applied to low contrast standard Lena image and other real life images.
