Outline of Final Research Achievements |
Like a surveillance camera image at nighttime, the signal value observed under an extremely dark situation, it is necessary to introduce some techniques for improving the statistical reliability to the process of the restoration. We examined the restoration method composed of three processing. That is, virtual multiplex imaging which is composed by pixel binning and redundant subsampling, moving image denoising using 3-dimentional DCT and super-resolution deblurring. While accomplishing the research, we found that 3-dimentional ST-DFT can represent moving image more sparsely than 3-dimentional DCT.
