本文提出了一種新的基于同質(zhì)性和時間自適應自組織神經(jīng)網(wǎng)絡(luò)（TASOM）的邊緣檢測算法。算法首先利用同質(zhì)性檢測到圖像的候選邊緣點，并根據(jù)這些點構(gòu)造TASOM網(wǎng)絡(luò)結(jié)構(gòu)；其次，利用Canny算子檢測到的邊緣點作為網(wǎng)絡(luò)訓練的特征點；最后，通過比較控制點和特征點調(diào)整TASOM網(wǎng)絡(luò)的連接權(quán)，實現(xiàn)對網(wǎng)絡(luò)神經(jīng)元的自動添加和刪減，達到保持邊緣的連續(xù)性和刪除冗余邊緣點的目的。試驗結(jié)果表明所提算法優(yōu)于傳統(tǒng)的邊緣檢測方法。

Abstract This paper presents a new algorithm for edge detection based on homogeneity and time adaptive self-organizing neural networks (TASOM). Firstly, the method uses homogeneity to extract the candidate edge points, and constructs the TASOM network according to these points; and then, make the edge points detected by Canny operator as
feature points of the TASOM network; finally, the weights of TASOM are updated to achieve the adding and deletion of neurons automatically by comparing the difference between control points and feature points; consequently, the aims that remaining the continuity of the edges and deleting the redundant points are achieved. The experimental results show that the
proposed method is superior to other algorithms.
