ABSTRACT: The seamless tiled display is an effective realization for the wide field and
high-resolution display of media; the technology of edge blending is the core
of seamless tiled display system and is also the hot-spot of Digital Light
Process (DLP). The paper introduces the technique of edge blending process
and puts 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 fusion algorithm
that using two addition parameters p and a, and finally adds Gamma operator
to further correction of the pixel brightness. Experimental results show that, the
proposed algorithm effectively eliminates the light generated by the edge of the
integration region and the image has good transitions, the proposed algorithm
reduces the output of the projector color differences by the value of SNR.
