| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Sparse coding represents observed signals effectively as a linear combination of a small number of bases which are chosen from the basis functions trained by the algorithm. The effectiveness of sparse coding for image processing has been confirmed in the areas of image compression, image denoising, and image separation. On the other hand, cloud computing is spreading in many fields. However, the cloud computing has some serious issues for end users, such as unauthorized use and leak of data, and privacy compromise, due to unreliability of providers and some accident. In this manuscript, we propose a secure sparse coding computation. It is shown that the secure sparse coding computation enables us to not only protects observed signals, but also have the same estimation performance as that of sparse coding with unprotected observed signals . | |
