Abstract:
The invention provides a method and system for decoding two-dimensional code using weighted average gray-scale algorithm. The method comprises: segmenting a received two-dimensional code image into bit regions each containing one bit data; presetting a shifting threshold, and shifting four original boundary lines of the bit region outwards by a distance of the shifting threshold to obtain four preset boundary lines; calculating an average gray-scale value of the bit region using the weighted average algorithm by taking an overlapping area between pixels inside the four preset boundary lines and the bit region as a weight; binarizing the two-dimensional code image according to the average gray-scale value of the bit region; and decoding the two-dimensional code image. The influence of the pixels which have an overlapping area with the bit region on the average gray-scale value of the bit region is considered, and the decoding accuracy and success rate are high.

Claim (Index 2):
The method for decoding two-dimensional code using weighted average gray-scale algorithm according to  claim 1 , wherein the shifting threshold is less than or equal to the width of one pixel.
