Web7 apr. 2024 · In this paper, we propose a novel adaptive visual saliency feature enhancement method for CBCT in IGRT. Firstly, we denoised CBCT images using a structural similarity based low-rank approximation model (SSLRA) and then enhanced the denoised results with a visual saliency feature enhancement (VSFE)-based method. Web26 sep. 2024 · sharp edges and transitions. Low rank matrices are especially bad at representing diagonal lines. For example, the identity matrix is a diagonal line seen as an image, and it is also impossible to compress using an SVD since all singular values are equal. On the other hand, images without any sharp transitions can be approximated

Web8 jan. 2024 · This paper introduces the bilinear bandit problem with low-rank structure. In each round t, an algorithm chooses a left arm xt from X ⊆Rd1 and a right arm zt from Z⊆Rd2, and observes a noisy reward of a bilinear form: yt=x⊤tΘ∗zt+ηt, (1) where Θ∗∈Rd1×d2 is an unknown parameter and ηt is a conditionally σ WebCompared with [32] which only utilizes the global low-rank structure of tensors, we consider additional local in-formation of the data set for completion via sparse coding. Compared with [35] which uses the truncated tensor nuclear norm for low-rank approximation, we employ the weighted nuclear norm as the surrogate of rank. The …
