| Outline of Final Research Achievements |
In this study, we developed a noise reduction method based on sparse coding for X-ray image as medical image processing algorithms, and we studied hardware implementation for the purpose of practical use. The major achievements were development of a dictionary design technique for sparse coding corresponded to Poisson noise and a fast atom selection method using initial inner product. These proposed method provided good noise reduction performance. On the other hand, we designed hardware of a fast processing algorithm using Cholesky decomposition, and evaluated the performance.
