Color Reversion of BAYER Pattern Image Using Signal Correlation

At present,there are two conventional methods of color reversion of BAYER pattern image from signal CCD.One is bilinear interpolation method,the other is edge-sensing method.According as correlates of the R,G, B channels in color image,we propose a new interpolation method to improve the image quality and SNR,sharpen edge of the image,reduce the number of error pixels.At same time,SNR and NCD methods are used to evaluate signal correlation method and two conventional methods.
