Edge Detection Based on Image Enhancement of Wavelet Transform and Modified Multi-scale Morphological Gradient

  • The multi-structure elements and multi-scale edge detection method is proposed based on image enhanced of wavelet transform.Four elements are used to detect multi-direc-tional edges of image at different scales,The more ideal image edges under the environment of existing noise are obtained by integrating the edge characteristics for various scale.During computation the computation is reduced by simplifying the different scales structuring ele-ments.The experiments show that compared with traditional morphological edge detection algorithms,the method possesses better edge locating ability and keeps the more edge de-tails,but also the ability of noise interference restrained is stronger.
