| Abstract: | Proposes a new edge detection algorithm based on mathematical morphology combining with wavelet transform, canny operation together. Uses wavelet transform to preprocess the image, uses the Canny operation is used to complete the preliminary edge detection. To solve the problem of boundary fault and fuzzy issue, uses the closure compute of mathematical morphology to fill and repair the edge fracture. The whole process was simulated in MatLab. Experiment results show the detected edge is clear and smooth, it is an effective algorithm to extract image edge, improving the detection accuracy and suppressing the noise. |
