适用于识别指定颜色的色调过滤视图

Hue-filter View Suited to Specific Color Recognition

为便于快速识别RGB图像中的红、绿、蓝或黄颜色,提出一种用像素的色调和色调可信度定量地评估像素对于指定颜色的隶属度的方法和彩色图像的色调过滤视图的定义,推导出直接由图像的R、G、B色彩分量计算指定颜色的色调过滤视图的公式。实验结果表明,用色调过滤视图来识别图像中指定的颜色具有较好的效果,并且受拍摄光照条件的影响较小。

For the benefit of swiftly recognizing the colors of red, green, blue or yellow on RGB images, a method to quantitatively evaluate the membership degree of pixel to a specific color by means of the hue and the trustworthiness of the hue is put for- ward, and the hue-filter view of color image is defined. Formulas to calculate the pixel values of the hue-filter views directly by the R, G, B components of images are presented. The experiment results indicate that recognition to a specific color on the huefilter view has better effect and it is insensitive to the illuminatinns nf the scenes.
