BHAVSAR, RAJAGOPALAN: DEPTH ESTIMATION WITH A PRACTICAL CAMERA 1 Depth estimation with a practical camera
Given an off-the-shelf camera, one has the freedom to move the camera or play around with its intrinsic parameters such as zoom or aperture settings. We propose a framework for depth estimation from a set of calibrated images, captured under general camera motion and parameter variation. Our framework considers the practical trade-offs in a camera and hence essentially generalizes the more cons...
متن کاملDepth Estimation with a Practical Camera
We propose a framework for depth estimation from a set of calibrated images, captured with a moving camera with varying parameters. Our framework respects the physical limits of the camera, and considers various effects such as motion parallax, defocus blur, zooming and occlusions which are often unavoidable. In fact, the stereo [1] and the depth from defocus [2] are essentially special cases i...
متن کاملA practical depth-of-interaction PET/MR detector with dichotomous-orthogonal-symmetry decoding
University of Texas MD Anderson Cancer Center, Houston, Texas, USA Conventional dual-end depth-of-interaction (DOI) PET detector readout requires two 2D SiPM arrays; with top and bottom SiPM reading the same pixel, there is information redundancy. We proposed a dichotomous-orthogonal-symmetric (DOS) dual-end DOI readout to eliminate this redundancy to significantly reduce SiPM usage, electronic...

متن کاملPerformance measurements of a depth-encoding PET detector module based on position-sensitive avalanche photodiode read-out.
We are developing a high-resolution, high-efficiency positron emission tomography (PET) detector module with depth of interaction (DOI) capability based on a lutetium oxyorthosilicate (LSO) scintillator array coupled at both ends to position-sensitive avalanche photodiodes (PSAPDs). In this paper we present the DOI resolution, energy resolution and timing resolution results for complete detecto...
