WebApr 13, 2024 · Deblending via then POCS algorithm To be convenient, we assume that one simultaneous source of data is blended using two independent sources, which correspond to two shooting sources in ocean bottom cable (OBC) acquisition. Therefore, the blending forward processing is given by in the common-receiver domain, d = Γ 1 d 1 + Γ 2 d 2, (1) WebThe convergence of projection on convex sets (POCS) algorithms is monotonic and exponential near the point of convergence, so it is reasonable to predict the limit point using a simple exponential regression For circumstances where the convergence of each coordinate direction is, in fact, monotonic, this results in a significant acceleration of …

WebGiven the two overlapping closed convex sets C and D, the POCS algorithm finds a point x ∈ C ∩ D by alternatingly projecting onto the sets C and D. To find a positive and F 2 -exact surface ... Web2 days ago · The OS-ASD-POCS algorithm is an ordered subset version of the well-known ASD-POCS algorithm [17]. ASD-POCS allows for the minimisation of separate convex optimisation problems, in this case, data minimisation and total variation minimisation, in an adaptative manner that ensures global convergence. ASD-POCS was proposed with SART …
Web3. POCS Algorithm The POCS approach to the SR reconstruction problem has been proposed in [7]. Let the motion information be provided. Then, a data consistency constraint set based on the acquisition model (2) can be defined for each pixel with each low-resolution (LR) image. The convex sets in any LR image are given by: WebJan 3, 2012 · There is not just one POCS image restoration program. POCS is a method which is applicable in different circumstances. For example, satellite images, fractal …
