摘要： In various embodiments, a parameter domain graph application generates UV-net representations of 3D CAD objects for machine learning models. In operation, the parameter domain graph application generates a graph based on a B-rep of a 3D CAD object. The parameter domain graph application discretizes a parameter domain of a parametric surface associated with the B-rep into a 2D grid. The parameter domain graph application computes at least one feature at a grid point included in the 2D grid based on the parametric surface to generate a 2D UV-grid. Based on the graph and the 2D UV-grid, the parameter domain graph application generates a UV-net representation of the 3D CAD object. Advantageously, generating UV-net representations of 3D CAD objects that are represented using B-reps enables the 3D CAD objects to be processed efficiently using neural networks.

摘要： Disclosed are an image processing method and apparatus, a computer storage medium, and an electronic device, which relate to the field of image processing. The method comprises: acquiring a diffuse map, and acquiring a shadow texel, located in a shadow area, in the diffuse map (S310); querying an average color lookup table according to spatial coordinate information of the shadow texel, and according to a query result, determining an average brightness difference corresponding to the shadow texel (S320); and determining restored color information according to the average brightness difference and color information corresponding to the shadow texel, and according to the restored color information, restoring the color information of the shadow texel (S330). By means of the method, a shadow in a diffuse map can be effectively removed, such that a model can be used in scenarios with any lighting conditions.

摘要： A viewpoint image processing method and a related device are provided, and relate to the artificial intelligence/computer vision field. The method includes: obtaining a preset quantity of first viewpoint images (S1201); obtaining a geometric feature matrix between the preset quantity of first viewpoint images; generating an adaptive convolution kernel corresponding to each pixel of the preset quantity of first viewpoint images based on the geometric feature matrix and location information of a to-be-synthesized second viewpoint image, where the location information represents a viewpoint location of the second viewpoint image; generating the preset quantity of to-be-processed virtual composite pixel matrices based on the adaptive convolution kernels and the pixels of the preset quantity of existing viewpoint images (S1204); and synthesizing the second viewpoint image by using the preset quantity of to-be-processed virtual composite pixel matrices (S1205). The method can improve efficiency and quality of synthesizing the second viewpoint image.
