redpajama_arxiv | 2,020 | Introduction
Many model-based computational imaging methods assume that data acquisition can be represented as a linear system of equations, such that
where b is the length- M vector of measured data samples, f is the length- N vector of unknown image voxel values, A is an M N matrix modeling the data acquisition ope... | 8,852 | academic |
redpajama_arxiv | 2,020 | Introduction
Dense and hot plasma structures are a common sight in the solar corona. These structures are mostly linear (in the sense that their lengths are much longer than their transverse scales) and are believed to trace local magnetic field lines. Some of them are closed, meaning both ends of the structure anchor... | 18,563 | academic |
redpajama_arxiv | 2,020 | Introduction
Increasing availability and sophistication of digital image editing tools cause a major problem of that we even can not believe what we see . Image forgery is becoming a global epidemic which deeply affects our daily life for that some forgers use elaborately forged images to spread fake news or... | 9,142 | academic |
