摘　　要：环状矩形分块主色调检索算法将图像分成环状矩形边缘区域、中心环状矩形区域和核心矩形区域,对最外层边缘区域不予处理,这可明显减少检索时间,且对检索效果影响很少。采用主色调检索使其具有平移、尺度不变性等优点。在对中心区域和核心区域采用不同比例主色调选择,可以体现主色调在核心区域较集中。而环状矩形具有圆形分块的旋转不变性,但计算更简单,实验验证,该算法对一些类别图像有较好的检索效果。A new method for image retrieval which is based on ring-like rectangular blocking and main color is proposed.It divides into the image the ring-like rectangle fringing field,the central ring-like rectangle region and the core rectangle region.No treatment is for the outermost edge area,this can significantly reduce retrieval time and little influence on retrieval effect.Main color retrieval with advantages is translate,scale invariance.Different proportions to center,and core areas main color selecting,can reflect the main color in the core area of greater concentration.ring-like rectangular has rotation invariance,but calculations easier Validated by experiments,for some categories the image has better search results.
