Deformation vector
WebBackground: High quality 4D-CBCT can be obtained by deforming a planning CT (pCT), where the deformation vector fields (DVF) are estimated by matching the forward projections of pCT and 4D-CBCT projections. The matching metric used in the previous study is the sum of squared intensity differences (SSID). The scatter signal level in CBCT ...

WebMar 28, 2016 · Recently, deformation methods [5,18,19] have been proposed to alleviate occlusions in urban areas. Deformation methods clear the line of sight by deforming the occluding objects and the surroundings. Deng et al. presented an automatic method that enabled an interactive context-aware visualization of the relevant urban features. WebThe meaning of DEFORMATION is alteration of form or shape; also : the product of such alteration.
WebJun 21, 2024 · The deformation vector is then obtained by calculating the vector between the position of the highest correlation and the center of the matrix. The initial deformation vector is further refined to sub-pixel accurate values by fitting a 2D Gauss curve to the directly neighbouring correlation values. To reduce noise, deformation vectors with a ... WebApr 12, 2024 · Abstract. Mechanisms are prone to stuttering or even jamming due to the deformation of components, especially for overconstrained linkages for which geometric conditions must be strictly satisfied. In this paper, joint clearance is actively introduced to release the local constraint so that the linkages can still achieve general movement …
WebOct 6, 2024 · Pseudo Ground-Truth Deformation Flow. We define a function that takes an object binary mask (silhouette as foreground and the rest as background) on a regular grid as input, and outputs a vector field for deformation. This vector field is treated as the pseudo ground-truth for the deformation flow. WebThe discussion extends to explain how deformation of a material is accommodated at the microscopic level. We will finish by addressing how the presence and properties of defects can increase or decrease the strength of a material. 5.2 Normal ... the Burgers vector and the tangent vector are at an angle, which is not either 90 degrees or ...
