Abstract: Color histogram is important feature in image classification system.Considering color histogram spatial relationship，spatial pyramid color histogram is proposed as images representation，which is the combination of image global features and block-based features.Making use of Support Vector Machine（SVM） and four kernel functions，image sets are trained and classified.The results on corel image database show that this feature can combine global features and spatial features effectively and have better classification accuracy.

Key words: image classification, spatial pyramid color histogram, Support Vector Machine（SVM）, global image feature
