In allusion to the rich color information of gastroscope images,make use of neighborhood color moment histogram and the primitive histogram after quantization and clustering in HSV color space,and then use PCA algorithm to reduce the dimensions to retrieve,at last use relevance feedback to make multi-retrieve.
针对彩色胃窥镜图像丰富的颜色信息,在HSV颜色空间量化聚类后,利用多邻域颜色矩直方图和原始的量化聚类直方图的方法,再运用PCA算法降维,进行检索,最后利用相关反馈技术进行多次检索。
