    摘要: A method for establishing a smooth geometric model based on data of a medical image includes: inputting or reading the data of the medical image; establishing a three-dimensional medical image voxel model based on the data of the medical image, smoothing the three-dimensional medical image voxel model, and establishing a three-dimensional voxel phantom tissue model based on the smoothed three-dimensional medical image voxel model; or establishing the three-dimensional voxel phantom tissue model based on the data of the medical image, and smoothing the three-dimensional voxel phantom tissue model. The method for establishing a smooth geometric model based on the data of the medical image smoothes the three-dimensional medical image voxel model or the three-dimensional voxel phantom tissue model to make it closer to the real situation of the human organ, thereby improving the reliability of the dose calculation to improve the quality of the treatment.

    摘要: This application relates to the field of modeling, and in particular, to a method and an apparatus for generating an expression model, a device, and a medium. The method includes: obtaining a reference expression model of an object, where the reference expression model is a facial model corresponding to a first expression (302); performing model transformation on a sample expression model set by using the obtained reference expression model, to obtain a target expression model set, the target expression model set including n expression models of a reference object, and a similarity between the reference object and the object being greater than a similarity threshold (304); and performing mesh deformation on the reference expression model of the object according to a model difference between a first expression model and a second expression model in the target expression model set, to generate a deformed expression model of the object (306). The second expression model and the deformed expression model are facial models corresponding to a second expression, and the second expression is different from the first expression.
