Dark Texture

Pre-Processing > Dark Texture

Highlights dark components of image textures that are no bigger than the specified window size. Also known as a bottom-hat filter, it computes the grayscale closing (grayscale erosion followed by grayscale dilation) of the Current Image by the specified window size, then subtracts the result from the Current Image.

1. Window Size

Window size (in pixels) to consider about each pixel to calculate the filter. Controls the maximum size of dark feature components to highlight.
