NONLINEAR SCALING IN VIDEO CONFERENCING

摘要

A method for video teleconferencing is disclosed. The method comprises receiving a first starting image with a first number of rows and receiving a second starting image with a second number of rows. The images are nonlinearly down-scaled to create a first scaled image and second scaled image respectively. Thus the numbers of rows in the scaled images are less than the number of rows in the starting images. Then, the first scaled image is combined with the second scaled image to create a transmission image for transmission.

1. A method for video teleconferencing, the method comprising:
receiving a first starting image with a first number of rows; receiving a second starting image with a second number of rows; down-scaling, with a processor, the first starting image to create a first scaled image with a number of rows fewer than the first number of rows of the first starting image, wherein the down-scaling is nonlinear downscaling; down-scaling, with the processor, the second starting image to create a second scaled image with a number of rows fewer than the second number of rows of the second starting image, wherein the down-scaling is nonlinear downscaling; and combining the first scaled image with the second scaled image to create a transmission image.
