Calculating image textures with GLCM – Alex Zvoleff

WebGLCM determines differences between surface textures through the collection of elements around a diagonal in the matrix for example, rough and smooth surfaces will be different and can easily be classified using GLCM [20]. The dimensions of GLCM are calculated by the gray level of image. More levels give more accuracy in extracting Web10 jul. 2015 · The GLCM is set up such that each pixel value is represented on each axis. We count the number of times each pair of grey levels occurs, for example, if angle = “0” and d = 1, for the grey level of 1, there is one 1:1 pair: While there are two 1:3 pairs: Continuing in this fashion for each grey level, we end up with a GLCM filled with counts. etsy template editor
