Abstract

A method for video teleconferencing comprises receiving a starting image with a number of rows and a number of columns. The starting image is downscaled with a dual-axis warping function to create a scaled image with a number of rows fewer than the number of rows of the starting image and a number of columns fewer than the number of columns in the starting image. Then, a transmission image is created from the scaled image.
