| Abstract | The paper has presented a fractal combining with wavelet idea for edges extraction, which firstly computes fractal dimension values of R, G, B components of every pixel in images, and then synthesizes color image by normalized fractal dimension values, finally decomposes histogram of synthetic image by wavelet transform to determine the threshold of extraction edges, at the same time, improved the thresholding segmentation based on wavelet transform –AEEM (Automatic Extraction Edges Method) which determines automatically the extraction threshold. Comparing with the histogram-based approach, the experimental results demonstrate that the approach yields better segmentation. |
