Abstract
In order to improve LOG filter performance for stereo vision, a four step pretreatment method was proposed. This method was divided into 4 steps: wiping out random noise by mean filter, reducing Gaussian noise by Gaussian filter, balancing brightness difference between stereo image pair through histogram equalization, and enhancing image edges and details by Laplace sharpness. Experimental results show that this four step pretreatment method can eliminate image noise and reduce brightness difference effectively.
