针对暗通道方法求暗通道及透射率时造成的块效应，提出一种多尺度参数方法，明显改善块效应，获得的透射率远比原方法清晰，最终去雾效果很不错。-Blockiness when　uated against the dark passages and transmittance caused by dark passages method, we propose a multi-scale method parameters, significant improvement in blocking transmittance obtained clearer than the original method, eventually went to the fog effect is very good.
