该方法针对图像中不同亮度区域进行亮度补偿，使得整个图像亮度背景趋于一致后，再进行通常的阈值分割。
The method compensates every area of different luminance proportion in order to make the luminance of part area near to that of the whole area, then segment image using ordinary methods.
本发明有效解决了在逆光拍照时不能自动检测逆光状态并自动对图像中主体对象的亮度进行补偿的问题。
This invention efficiently solves the problem of being unable to auto-test the backlighting state and auto-equalize the luminance of the main object in the image when backlighting shooting.
参数分析表明补偿后的显示图像可以很好地掩盖表面彩色图案，并表现出更高的亮度或者亮度对比度。
The parameter analysis indicates that the compensated displays could well conceal the surface pattern and tend to exhibit higher lightness or lightness contrast in the camera.
