IMAGE SPL Directory

The IMAGE directory contains SPL functions useful in image processing applications. The following files are included:

BRIGHTEN	Brightens or darkens an image.
DCT2	Calculates the 2D Discrete Cosine Transform.
FFT2	Calculates the two-dimensional (2D) FFT of an array.
FFTP2	Calculates the 2D FFT of an array in polar form.
HISTEQ	Performs histogram equalization of an image.
IDCT2	Calculates the 2D Inverse Discrete Cosine Transform.
IFFT2	Calculates the 2D IFFT of an array.
IFFTP2	Calculates the 2D IFFT in polar form.
IMAGE24	Converts an image with a colormap to a 24 bit color image.
IMINTERP	Interpolates an image.
RGB2MONO	Converts an RGB image to an 8 bit monochrome image.
RGBIMAGE	Creates a 24 bit image from red, green and blue components.
