Edge preservation measurement comparison. The blue line shows the β values obtained by the conventional bilateral filter and the red line shows the β values obtained by the proposed bilateral filter. The proposed filter has much better performance in edge preservation than the conventional bilateral filter after σr reaches the optimal point.
