| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years,IR method showing the non-linear behavior is used in the CT diagnosis. Evaluation method of the filter from the past, is the applicable evaluation method only continuous function. Therefore it is difficult to evaluate the IR method of filter. Richard et al. [3] has been reported using a discrete function. Also, data used is evaluated image using a discrete data and many images. We used a fewer number of images in the image of the discrete IR method further performs the fitting of a continuous function. Therefore, we can objectively perform a two-stage noise rejection and edge enhancement. And I have established a evaluation method of each filter. | |
