摘要
为满足专业数码相机要拍摄出高清晰度高保真度图像的要求,提出一种应用于Bayer型颜色滤波阵列的相关性小波插值算法。基于图像红绿蓝三基色之间的相关性,首先对图像进行小波分解,其次进行阀值比较,最后小波重构得到最终插值图像。实验表明,此算法插值的图像具有较高保真度,图像边缘部分更清晰,平滑,更接近原始图像。
In order to satisfy the professional digital camera＇s requirement that is to get the image with high definition and fidelity,a correlated wavelet interpolation which is applied on the Bayer color filter array （CFA）is proposed.Based on the correlation among the R,G and B of the image,the algorithm decomposes the original image with wavelet analysis,compare the results with threshold and reconstruct the image with wavelet analysis to get the final interpolated image.The result illustrates the higher fidelity of the algorithm,furthermore,the edge within the result is clearer and smoother,the result is closer to the original image compared with other interpolate algorithm.
