This module provides the DCT algorithm

Functions

DCT(impath) : Main driver for DCT algorithm

Args:
    impath: Input image path
Returns:
    OutputMap: OutputMap

GetDCTArtifact(im) : Determines DCT artifacts.

Args:
    im: Input image

Returns:
    BMat: OutputMap

hist3d(arr, bins) :

matlab_style_gauss2D(shape=(3, 3), sigma=0.5) : 2D gaussian mask - should give the same result as MATLAB's fspecial('gaussian',[shape],[sigma])
