摘要
分析了MPEG-7标准中推荐的主颜色描述符和颜色结构描述符各自的优缺点,并提出了一种新的空间主颜色描述符,它采用图像中少数几个代表性颜色和它们的空间分布信息来表征整幅图像。实验表明,空间主颜色描述符集合了主颜色描述符和颜色结构描述符的优点,具有检索精确高、提取速度快和存储空间小的优点.
A new spatial dominant color descriptor(SDCD) is proposed firstly,based on the analysis of the dominant color descriptor(DCD) and the color structure descriptor(CSD) recommended in MPEG-7 standard.It uses some representative colors and the spatial distribution information among them to represent the whole image.Experimental results show that SDCD combines the advantages of DCD and CSD such as exactness,efficiency and compactness.
