A co-occurrence matrix or co-occurrence distribution (also referred to as : gray-level co-occurrence matrices GLCMs) is a matrix that is defined over an image to be the distribution of co-occurring pixel values (grayscale values, or colors) at a given offset. It is used as an approach to texture analysis with various … See more Given a grey-level image $${\displaystyle I}$$, co-occurrence matrix computes how often pairs of pixels with a specific value and offset occur in the image. • The offset, $${\displaystyle (\Delta x,\Delta y)}$$, … See more Co-occurrence matrices are also used for words processing in natural language processing (NLP). See more • Gray level size zone matrix See more Co-occurrence matrices are also referred to as: GLCMs (gray-level co-occurrence matrices) GLCHs (gray-level co-occurrence histograms) spatial dependence matrices See more Whether considering the intensity or grayscale values of the image or various dimensions of color, the co-occurrence matrix can measure the texture of the image.
