摘　　要：在特定颜色空间中数字图像的量化对提取其相应颜色直方图有明显的影响。本文比对分析了在HSV颜色空间中均匀量化与非均匀量化对数字图像颜色直方图提取的影响,并以国家非物质文化遗产——南通蓝印花布为例,综合分析了南通蓝印花布数字图像的特点,利用JAVA EE环境下的Open CV函数库实现两种量化方法下颜色直方图的提取,确定了HSV颜色空间非均匀量化在颜色直方图提取方面的优势。In a specific color space, quantization of digital image has significant influence on the ex- traction of the corresponding color histogram. The effects of uniform and non - uniform quantization of digital image on color histogram extraction in the HSV color space were analyzed. Taking the na- tional intangible cultural heritage - Nantong blue calico as an example, the characteristics of its digit- al image were analyzed. The extraction of color histogram by using OpenCV function library function JAVA EE environment to achieve the two quantization methods and proved the non -uniform quanti- zation extraction has advantages over uniform in extracting histogram at HSV color space.
