摘要
为解决实际应用中的反马赛克问题,给出一种自适应比例合成算法.对G通道进行梯度比例合成插值,R,B通道采用G通道的梯度校正双线性插值结果,从复合峰值信噪比(CPSNR)和计算量两个角度,将自适应比例合成算法与其它几种典型的反马赛克插值算法进行对比.自适应比例合成算法以较小的计算量获得较高的CP-SNR,适合于实际应用.该算法已应用在某多通道CMOS图像采集系统中,效果理想.
Resolve demosaicking problems in application, and a new adaptive proportional combination algorithm is presented. G channel interpolation method in proportional combination, and the grids of G channel is used to calibrate the errors of bilinear interpolation of R and B channels. On aspects of composite peak signal noise ratio （CPSNR） and computation, the adaptive proportional combination algorithm is compared with several other typical demosaicking methods. The proportional combination algorithm fits practical application for some CPSNR with less computation, The algorithm is employed in a multiple channel CMOS image sampling system and the application test results are excellent.
