Abstract:
The spatial median is but one method of summarizing a set of data. Other examples include the mean and median. In this seminar, we will look at four common approaches to reconstructing noise-affected images using data summary techniques. The purpose of these algorithms is to remove the noise from a signal that might occur through the transmission of an image. A new algorithm, the Spatial Median Filter, is introduced and compared to the more common techniques. Experimental results demonstrate that the proposed algorithm is comparable to these techniques. A modification to this algorithm is introduced to achieve more accurate reconstructions over other popular techniques.
