Screen saver/Graphics: What was the large circle on the Help Defeat Cancer graphic, and what did the Distance and Filter mask graphics mean?
The round image at the left side of the application window showed the image of a slice of tissue sample, which the members computer processed. The tissues may have been stained with certain compounds to better highlight certain features, such as the nuclei of cells. The square “Filter Mask” in the upper right showed how one of many of the mathematical filters responded to a particular square subsection outlined in the tissue image at the left. The shading showed that particular filter’s response value for each point ranging from dark (low response) to light (high response). You could see some correspondence between the outlined area and the Filter Mask. The shading in the “Distance Mask” at the lower right showed how the particular filter’s response is relevant to a mathematical pattern being developed over all of the filters. This is a highly oversimplified description of what was displayed and computed. But, it does let you see a glimpse of the computation that was performed.
