The presence of speckle in an image reduces the resolution of the image and the detectability of the target. Many speckle reduction algorithms assume speckle noise is multiplicative. We instead model the speckle according to the exact physical process of coherent image formation. Thus, the

The talk represents a summary of the enabling technologies for, and an amalgamation and interpretation of findings from, our DIP experiments over

We are exploring the unique challenges presented by such a Grand Challenge System Integration Experiment in the context of our own IMS implementation, the Media Immersion
