In this paper, the performance of a noise reduction method based on a local contrast
modification function, is evaluated on computer simulated and real phantom
images. First, a local contrast is computed for each pixel, depending on its neighborhood
statistical properties. An optimal contrast modification function, meeting
some requirements that ensure noise reduction, is then applied. This function is
found by solving an optimization problem using the mean squared error as a criterion.
Finally the enhanced pixel value is calculated using an inverse local contrast
method. This method has two advantages: being very easy to implement and providing
matlab
