Detailed Description

The DCT class provides a reference implementation for Discret Cosine Transform.

Constructor & Destructor Documentation

DCT()

pic::DCT::DCT ( )

inline

DCT.

Member Function Documentation

inverse()

static Image* pic::DCT::inverse ( Image *  imgIn, Image *  imgOut, int  size = 8  )

inlinestatic

inverse computes the inverse DCT transformation.

Parameters

imgIn	is an input image in the DCT domain.
imgOut	is an output image; i.e. imgIn in spatial domain.
size	is the size of blocks (size * size) for computing the DCT.

Returns

transform()

static Image* pic::DCT::transform ( Image *  imgIn, Image *  imgOut, int  size = 8  )

inlinestatic

transform computes the forward DCT transformation.

Parameters

imgIn	is an input image.
imgOut	is an output image; i.e. imgIn in the DCT domain.
size	is the size of blocks (size * size) for computing the DCT.

Returns
