Colorizing Algorithm Based on Wavelet Transform
|
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.
