| ===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,
