| Outline of Final Research Achievements |
In this project, we proposed a multidimensional transform with the redundant, non-separable, overlapped, symmetric, compact-supported and tight property. We also conducted the theoretical analysis, design, implementation, and application development. First, we extended the existing non-separable lapped orthogonal transform to redundant configuration and clarify its properties. As well, we proposed an example-based learning design method and showed its effectiveness. In addition, we showed the possibility of real-time processing through GPGPU/FPGA implementation. Besides, it was applied to image/volumetric data restoration and validity was confirmed. We also extended the proposed transform to complex coefficient type as preparation for application development to complex image restoration processing.
