For filtered back-projection of a projection image data set, the projection image data set is cosine-weighted. The cosine-weighted projection image data set within the image plane of the projection image data set is subjected to a two-dimensional Radon transformation. The Radon transform of the ...
6. 3.3 Filtering Projection Artifacts for Supervision In a depth completion setting, the given LiDAR depth can also be used as supervision data, as in [47]. Nevertheless, the approach in [47] did not take into account the noise present in the data. The given real-domain LiDAR input is ...
A new method for focus measure computation is proposed to reconstruct 3D shape using image sequence acquired under varying focus plane. Adaptive histogram ... R Minhas,AA Mohammed,QMJ Wu - 《Pattern Recognition》 被引量: 40发表: 2011年 A statistical and Wiener filtering algorithm based on the ...
The electronic device 100 also may rely on non-image information for position/orientation detection. This non-image information can be obtained by the electronic device 100 via one or more non-image sensors (not shown in FIG. 1), such as a gyroscope or ambient light sensor. The non-image ...
A generalized framework [21] was proposed to solve a range of image-based graphic problems. The framework approximated global regularization problem, which is computation costly, with a fast iterative joint filtering operation. This framework can deal with applications such as disparity estimation, ...

The reconstruction of amplitude and phase is performed by low-pass filtering of the sideband in the Fourier transform of the hologram (Fig. 7c) yielding amplitude and phase images (Fig. 7d,e) with a spatial resolution of about 5 nm. In the Wentzel-Kramers-Brillouin (WKB) ...
(Wooet al., 1990): an advantage when it comes to complex scenes. However, the depth map is prone toaliasingproblems, of which some have been improved (Hourcade, 1985;Reeveset al., 1987) using some filtering techniques. In this Gem, we attempt to reexamine the Moiré Pattern aliasing ...

Defocus image is equivalent to the low-pass filtering for focused image. The larger the defocus degree is, the more high-frequency components are filtered out. Therefore, the defocus degree can be calculated by using an operator sensitive to high-frequency components. In this work, we use sum...
