边缘检测是图像处理一个重要的环节,为了有效提取目标边缘,提出一种基于canny算法的改进算法,主要从两方面进行的改进,采用中值滤波代替高斯滤波对图像的噪声进行滤除和采用迭代法计算高低双阈值。实验的仿真结果很好地验证了改进算法的性能:在保留边缘信息的同时,很好地抑制了噪声的干扰,可以提高图像边缘检测效果。
邊緣檢測是圖像處理一箇重要的環節,為瞭有效提取目標邊緣,提齣一種基于canny算法的改進算法,主要從兩方麵進行的改進,採用中值濾波代替高斯濾波對圖像的譟聲進行濾除和採用迭代法計算高低雙閾值。實驗的倣真結果很好地驗證瞭改進算法的性能:在保留邊緣信息的同時,很好地抑製瞭譟聲的榦擾,可以提高圖像邊緣檢測效果。

Edge detection is one of the important parts of image measurement. In order to pick up ef-fectively the edge of the target,an improved algorithm based on Canny algorithm is put forward. The algo-rithm improved in two major areas. Adopt median filter to replace the Gauss filter which is in Canny arith-metic to remove noise and calculate the optimal high and low dual-threshold through iteration arithme-tic. The experiments prove that the proposed arithmetic has the advantage of noise restraining and detail keeping in the field of images management,can better detect the edges of the images,and improving the image edge detection.
