Gaussian blurred image pyramid, depicting the scale space of an image
The Gaussian convolved images appear blurred in comparison to the original
image simulating the scale-space visualization of the image. The high fre-
quency corresponds to minute image details that are never common between
two different images so these are removed. The blurred images are subse-
quently subtracted from each other to again remove details in two subsequent
blurs. These successive blurred images in each stage of convolution are desig-
