摘要
提出一种以纹理相似度为依据的颜色迁移算法。通过提取图像的多维纹理特征进行主成分分析和线性判别分析,构建纹理特征空间,以度量像素点邻域的纹理相似度,并以纹理相似度为依据,对图像进行分割,在分割后的局部区域,建立纹理相似度与色度信息的映射关系,实现颜色迁移。实验结果表明,基于纹理相似度的颜色迁移,可解决颜色在边界处的误扩散问题,颜色迁移效果较好。
A color transfer algorithm based on texture similarity was proposed by extracting multi-dimensional texture feature information of the image, with multi-dimensional texture information analyzed by principal component analysis（PCA） and linear discriminant analysis（LDA）. The texture feature space was constructed. The image was then divided into different areas according to the similarity in the pixel neighborhood. In the divided areas, the mapping relation between texture similarity and chroma information was established to realize the color transfer. Experimental results showed that color transfer on the basis of texture similarity could solve the problem of color error diffusion in image edge with good color transfer effect.
