Purpose
Calculates FFT for texture analysis.
Synopsis
- y = fft_texture(x,options)
Description
FFT_TEXTURE can be used to characterize texture in a gray-scale image.
INPUTS
- x = MxN matrix (e.g and image layer).
OUTPUTS
- y = 2x1 cell array. Each cell contains a vector of the mean square root of the FFT power spectrum. Each cell corresponds to the FFT calculated for 2 directions
- y{1} is down the rows (top-to-bottom), and
- y{2} is down the columns (left-to-right).
Options
options is a structure is a structure array with the following fields:
- plots: [ 'none' | {'final'} ] governs level of plotting,
