摘要: 提出一种基于二进小波变换的图像边缘检测算法。二进小波利用模局部极大值来提取图像的多尺度边缘信息并具有平移不变性,因此二进小波图像边缘检测具有特征提取快和边缘检测精确等特点。图像边缘检测的对比实验结果表明,二进小波的边缘检测比文献[4]中的实验效果好,细胞边界明显,图像边缘更为清晰。

Abstract: This paper proposes an image edge detection algorithm based on dyadic wavelet transform. Dyadic wavelet uses modulus local maximum to extract the multiscale edge information and has the shiftinvariant features, so it has fast feature extraction and accurate edge detection. Comparison of edge detection results show that dyadic wavelet edge detection has better effect than reference[4], with obvious cell borders and clear edge.
