实现matlab gui 界面的人脸检测的改进算法，效率更高(Achieve matlab gui interface improvements face detection algorithm, more efficient)

Illumination is one of the most significant factors affecting the appearance of an image. It often leads to diminished structures or inhomogeneous intensities of the image due to different albedos (texture) of the object surface and the shadows cast from different light source directions.
