Abstract: In one embodiment, a system may access an input image of an object captured by cameras, and the input image depicts appearance information associated with an object. The system may generate a first mesh of the object based on features identified from the input image of the object. The system may generate, by processing the first mesh using a machine-learning model, a position map that defines a contour of the object. Each pixel in the position map corresponds to a three-dimensional coordinate. The system may further generate a second mesh based on the position map, wherein the second mesh has a higher resolution than the first mesh. The system may render an output image of the object based on the second mesh. The system disclosed in the present application can render a dense mesh which has a higher resolution to provide details which cannot be compensated by texture information.
