| 摘 要： | 为了快速有效地进行图像染色,提出了利用2维小波变换进行灰度图像染色的新方法,该方法先将图像变换至小波域中,再利用文献4]方法对低频分量进行染色;然后通过逆变换重构被染色图像来得到染色结果。实验表明,该算法不仅改进了染色效果,并且在染色速度上也有明显提高。

| Abstract: | In order to implement colorization more quickly and effectively, a novel method for colorizing grayscale images using 2D wavelet(TDW) compositions is proposed in this paper.Based on the method in the reference 4],a grayscale image is colorized in wavelet domain by enduing colors to its Low-Low(LL) frequency subband,and the ultimate result can be retrieved through wavelet reconstruction.According to the experimental results,this algorithm not only improves the colorizing result but also greatly accelerates the processing speed. |
