摘要
人体器官的健康状况可以在虹膜颜色上体现,针对虹膜拍摄过程中设备差异造成的颜色偏差问题,采用直方图匹配的方法来校正颜色。以同一人的一副虹膜图像为标准,将其它认为存在颜色偏差的图像分别在R、G、B通道进行直方图匹配,得到颜色校正后的图像。通过实验证明了该方法适用于不同设备间采集颜色效果存在差异的情况,匹配效果达到了89%。
The health status of human organs can reflect on the color of iris. In connection with partial color that made by the difference between devices in taking iris pictures, use a method of histogram matching to correct color. Consider one iris image of the same person as the standard, use other partial color iris image to conduct histogram matching through R、G、B channel, to get the image after color correction. The experiment prove this method suit for color difference between different devices, the matching effect reach 89%.
