【摘要】 提出一种综合图像的色彩信息、灰度信息和空间信息提取图像的特征向量的方法。该方法首先将图像从RGB空间转化为HSV空间，并进行非均匀量化；其次将彩色转化为灰度图像；然后将图像划分成互有重叠的4块，分别求出每块图像的色彩直方图、灰度直方图；最后采用这8个直方图作为图像的特征向量对图像进行检索。更多还原

【Abstract】 This paper presents a method of using the information of color, grey level and space as image feature. In this method, images are converted from RGB space to HSV space and colors are divided unequally , then images are divided into 4 part overlaply and the color histogram and grey level histogram are extracted. At last, these histograms are used as image features to retrieval image.更多还原
