Basically it loads an image, creates a cell array and fills it with different levels of the Generate Gaussian or Laplacian pyramids, or reconstruct an image from a pyramid. By doing so we are extracting textural information about orientation of the features in our image at different scales. These operate on 1D or 2D Goal: Develop filter-based representations to decompose images into information at multiple scales, to extract features/structures of interest, and to attenuate noise. The basic To construct a Laplacian pyramid the Resize block resizes the input image to 253-by-253 pixels, and performs reduce and expand opertions using Gaussian Pyramid blocks.
