摘要
针对传统彩色直方图检索方法只考虑了颜色在图像整体上的分布,没有考虑颜色在图像局部上的空间分布的缺点,提出了一种基于同一颜色最大连通面积直方图改进方法。该方法分析了具有相同颜色的像素在空间分布上的差异,在传统直方图中融入了同一颜色构成的最大连通区域的面积信息,达到了较好的检索效果。
The traditional color histogram retrieval method only considered the color of the image on the overall distribution, but not considered local color in the image of the spatial distribution of defects. This paper presents an improved method of largest connectivity area histogram based on the same color. The method analyzes the pixels with the same color in the spatial distribution of the difference. To reach a better search result, it inosculates the same color histogram with largest connectivity area in traditional histogram.
