表征煤泥浮选泡沫图象特征的最佳色彩方案

针对煤泥浮选泡沫图象的表征方法问题 ,进行了实验室浮选柱试验 ,采集了 5 1组煤泥浮选泡沫图象 ,研究了煤泥泡沫图象的三种色彩表示系统 ( RGB,YCb Cr,灰度 ) ,分析了泡沫图象的亮度、色调及 RGB三分量的分布规律 .结果表明 ,精煤泡沫图象是灰色的 ,且色彩信息量非常少 ,在进行煤泥泡沫图象处理和识别时 ,可以采用图象的 RGB三个单独分量进行计算 ,也可以用平均灰度和公式法亮度进行计算 ,这样可以减少三分之二的数据传输量和计算量 ,加快图象处理速度 .

Optimum Color Scheme for Coal Flotation Froth Image Characteristic

Aiming at the problem of showing coal flotation froth image ,51 group images of coal flotation froth have been collected in laboratory. The images of coal flotation froth using three kinds of color system (RGB, YCbCr, Gray ) were discussed; and the rule of brightness ,hue and the three weights of RGB were analyzed. The result indicates that the refined coal froth image is of grey level and has few color information. For processing and recognizing the froth images, three single components of RGB , average grey,or brightness can be employed for calculation , thus some two thirds of transmitted and calculated data can be reduced, making the image process be improved.
