| 摘 要： | 在利用颜色特征对饭菜类型进行识别的过程中,为减少环境光照变化对识别结果的影响,采用了Gray World算法对图像色偏进行调整。在Fedora core 6下,利用V4L来控制摄像头获取图像数据。试验结果表明,使用了此算法后识别准确率提高了9.41%。

| Abstract: | In the process of using color feature to identify the different meals,gray world algorithm was used to reduce the effect caused by the changes of ambient light.Image data was obtained by using V4L to control the camera under the platform of Fedora core 6.Results show that recognition accuracy rate of this algorithm was improved of 10.8%. |
