WebExtracting texture features from images Texture is the spatial and visual quality of an image. In this recipe, we will take a look at Haralick texture features. These features are based on the co-occurrence matrix (11.5) defined as follows: In equation 11.5, i and j are intensities, while p and q are positions. WebJul 3, 2024 · CLAHE Image. As you can see from the image above CLAHE gives a much better result compare to the normal equalized image. But it still has a lot of noise, Let’s see how thresholding works out to get better results. To get a better result on images use .tiff file format rather than .jpeg file format
