These are probably the simplest examples of filters. They consist of a n × m kernel that “moves” through the image and applies a specific operation (e.g. the minimum) to the neighbourhood of each pixel. For instance, imagine that our image contains the following values.

WebWhen we apply a filter, we consider rectangular groups of pixels surrounding each pixel in the image, in turn. The kernel is another group of pixels (a separate matrix / small image), of the same dimensions as the rectangular group of pixels in the image, that moves along with the pixel being worked on by the filter.

Web26 jul. 2024 · Once again, we can use the math above to fill in a picture showing us what is happening at the level of the image and the kernel. We can see by lining up the appropriate kernel indices with the input image indices that we end up with the kernel “facing the original direction” i.e. in cross-correlation the kernel is not flipped. Summary WebOn the basis of a satellite image that I have as a reference (and the specific texture it contains) I want to design a gabor filter bank. The idea is that this filter bank can be applied to other satellite images to recognise the extent of a certain texture.
