ABSTRACT:
A method of operating a computing machine for reducing speckle noise in video images, particularly radar images, utilizes a complementary hulling technique on vertical pixel grids of the array. The vertical pixel contours which are subjected to the complementary hulling are derived from intersections of vertical grids with conceptual superposed gray-scale surfaces which have front end values corresponding to the gray-scale pixel values. The invention provides the significant advantages of decaying small image features, such as speckle noise at a significantly faster rate than large image features, such as target returns.
