Abstract
In order to solve the keystone distortion of images when a projector is used. A new algorithm transforming pixel spatial position using edge preserving interpolation is proposed to implement projector keystone correction. First, the scaling factors, the start point positions and the end point positions are calculated according to different rows, then the edge preserving interpolation algorithm are used according to the space positions. Experimental results demonstrate that the algorithm can not only implement keystone correction, but also preserves the edge effectively. It can be used in the chip of projector video processing.
