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.
Claims18
A method for video teleconferencing, the method comprising:
- receiving a starting image with a number of rows and a number of columns;
- down-scaling, with a processor, the starting image 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, wherein the down-scaling includes a dual-axis warping;
- and
- creating a transmission image from the scaled image.

A computer readable storage device with an executable program for video teleconferencing stored thereon, wherein the program instructs a processor to perform:
- receiving a starting image with a number of rows and a number of columns;
- down-scaling, with a processor, the starting image 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, wherein the down-scaling includes a dual-axis warping;
- and
- creating a transmission image from the scaled image.
