WebThe Wavelet Transform decomposes a function into a set of wavelets. Two main aplications for Discrete Wavelet Transform are image denoise and image compression (since this is a work for Image Processing subject, but Wavelet Transform can also be used for 1D examples). 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.
