void bilinear_resample_channel (coeff_t **input_channel, coeff_t **output_channel, int input_width, int input_height, int output_width, int output_height)


Detailed Description

It is well known that human eye is less sensitive to color than intensity. It is worthwhile to utilize this fact. We can store chroma channels with lower resolution than luma. One can achieve this through channel resampling procedure. At the moment EPSILON library uses bilinear resampling algorithm.
