CEDD: Color and Edge Directivity Descriptor
FCTH: Fuzzy Color and Texture Histogram
JCD: Joint Composite Descriptor
CEDD和FCTH都是基于模糊理论的对对象纹理特征的一种直方图描述,JCD是这两种特征的一种组合.
推荐参考下面两篇论文：
1:S. Α. Chatzichristofis and Y. S. Boutalis, “CEDD: COLOR AND EDGE DIRECTIVITY DESCRIPTOR - A COMPACT DESCRIPTOR FOR IMAGE INDEXING AND RETRIEVAL.” « 6th International Conference in advanced research on Computer Vision Systems ICVS 2008», May 12 to May 15, 2008, Santorini, Greece
2:S. A. Chatzichristofis and Y. S. Boutalis, “FCTH: FUZZY COLOR AND TEXTURE HISTOGRAM- A LOW LEVEL FEATURE FOR ACCURATE IMAGE RETRIEVAL” «9th International Workshop on Image Analysis for Multimedia Interactive Services”, Proceedings: IEEE Computer Society , May 7 to May 9, 2008, Klagenfurt, Austria
描述图像的特征有很多,有公开的也有不公开的；
对边,对纹理,对色彩,对角点等都有不同的描述；
也有对这些不同的组合的.
没有什么好建议,楼主只能多看论文才能了解更多了.
