Image Retrieval Based on Improvement Histogram and Spatial Feature
Junding Sun · Infrared Technology · 2007
A new image retrieval algorithm based on the main region’s area histogram was proposed.In order to reduce the calculation and time complexity,the gray is quantized according to human vision firstly.Then,the spatial distribution of the adjacent regions with the same gray level is further analyzed and extracted as the spatial feature.Finally,the spatial feature and its main region’s area are used as indexes.Experiment results show that this method is more effective in image retrieval than histogram and the main region’s area histogram.
