Directed at the haze conditions, the resulting single image degradation, therefore, the images that require high visual effects need to restore. The optimized algorithm based on dark channel prior improve the way of getting the atmospheric light vector A and the transmittance t(x,y). First using single threshold segmentation find the sky region, then combine with skyline algorithms can locate the precise atmospheric light vector A; then adopting improved Constrained least-square filter optimize the initial transmittance t(x,y) and get optimized transmittance t1(x,y), and finally restore degrade image by physical model of atmospheric with the resulting atmospheric light vector A and optimal transmission t1(x,y). the improved defogging algorithm not only retained meticulous edge detail, but also has removed image noise efficiently. Experimental results show that compared with the he method, the improved method short defogging processing time, and improve the image effect simultaneously.
