摘要
针对亮度不均匀的彩色图像进行RGB、HSV颜色空间的双重同态滤波,建立同态滤波器、并进行相应的系数修正,可保证彩色图像色调、饱和度基本不变,且能够校正图像的光照不均,有利于彩色图像后续的处理。实验结果表明,该方法简便、有效。
The paper correct uneven brightness of color image in RGB,HSV color space with the double-homomorphic filtering ,establish Filter and correct coefficient.The correction method can correct uneven brightness of color image with image of hue,saturation no distortion ,which benefits color image processing. Experiment results show that the method is simple,effective.
