- W2373752833 abstract "Ostu algorithm has become commonly used as image binarization algorithm because of its simplicity in realization,but it can not deal with the QR-Coded image under non-uniformed illumination.This paper puts forward a solution to overcome this disadvantage.Firstly,it adopts the improved homomorphic filtering algorithm to enhance the QR-Coded image quality to eliminate the negative effect of the non-uniformed illumination,then the QR-Coded image is binarized by the Ostu algorithm.Experimental results show that this algorithm can effectively overcomes the influence of non-uniformed illumination,and the recognition rate of the QR code can be improved." @default.
