Algorithm of edge blending based on the nonlinear function

The paper introduce the technique of edge blending process that is the key technique of the seamless tiled system and put forward the improved algorithm of edge blending in order to eliminate the edge of the light generated regional integration and achieve seamless connection. the algorithm is the modification of existing blending algorithm that using two addition parameter p and a, and add Gamma operator to further correction of the pixel brightness. finally, the color/brightness to match the output to be a certain degree of processing. Experimental results show that, the proposed algorithm effectively eliminates the light generated by the edge of the integration region and the image have good transitions, the proposed algorithm reduces the output of the projector color differences by the value of SNR.
