| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This report proposes 3-D OCT data denoising with non-separable oversampled lapped transform (NSOLT), which the authors proposed as a previous work, and examines the effectiveness. NSOLT is a lattice-based redundant transform which satis es simultaneously the symmetric, real-valued and compact-support property. It is possible to apply learning based design by examples. NSOLT is capable of having rational redundancy by controlling the number of channels P and decimation ratio M. In this study, a denoising technique is proposed by combining iterative hard thresholding （IHT） and NSOLT, and the performance of the proposed method is evaluated for 3-D OCT data. It is veri ed through robust median noise estimator and structual similarity index measure （SSIM） that the proposed technique yields effective denoising performance. |
