由于光照不均而造成的燃油喷雾液滴图像亮度不均，致使图像不能够有效进行阈值分割。
Nevertheless, owning to the uneven brightness, the image of fuel droplet could not be segmented efficiently.
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.
