| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this report, we propose an effective denoising method to attempt to denoise mammographic images. The method is based on using hierarchical correlation of the coefficients of discrete stationary wavelet transforms. The features of the proposed technique include iterative use of undecimated multi-directional wavelet transforms at adjacent scales. To validate the proposed method, computer simulations were conducted, followed by its applications to clinical mammograms. Mutual information was used as an evaluation measure in the present study. The results show that the proposed method has the potential to effectively reduce noise while maintaining high-frequency information. | |
