WebAug 30, 2024 · To address this issue, dictionary learning-based THz CT reconstruction (DLTR) model is proposed in this study. Especially, the image patches are extracted from other state-of-the-art reconstructed images to train the initial dictionary by using the K-SVD algorithm. Then, the dictionary can be adaptively updated during THz CT reconstruction. WebJun 1, 2024 · Edge detection is the first step in image recognition systems in a digital image processing.
