WebDifference of Gaussians. In imaging science, difference of Gaussians ( DoG) is a feature enhancement algorithm that involves the subtraction of one Gaussian blurred version of an original image from another, less blurred version of the original. In the simple case of grayscale images, the blurred images are obtained by convolving the original ... WebNov 5, 2008 · After applying a land mask (when necessary) to each image, the SDWS images were subjected to Gaussian high- and low-pass, and high pass local entropy, local standard deviation, local median, and Sobel edge detection filters. The filtered images were then assessed manually. The Gaussian filters proved most beneficial in highlighting the ...
