基于 Canny 算子的图像边缘检测方法改进研究
Improvement of Image Edge Detection Method Based on Canny Operator
摘要
Abstract
In view of the defects of the traditional Canny operator in smoothing image ,gradient calculation and thresh-old selection ,an improved scheme is proposed in this paper .The method uses a weighted median filtering instead of the Gaussian filter ,3 × 3 neighborhood four direction partial derivative is used to replace the 2 × 2 neighborhood two direction to obtain the gradient magnitude and direction ,and uses Gradient histogram to determine high and low threshold instead of man-made arbitrarily set .The simulation experimental results show that the improved Canny operator to improve the detec-tion accuracy and have better continuity .关键词
