Abstract

The embodiment of the invention provides a parameter inference method and device, and relates to the technical field of prediction or optimization, and the parameter inference method comprises the steps: receiving a plurality of key points of a human body part, wherein the plurality of key points are used for reflecting the features of the human body part; and processing the plurality of key points by using a trained neural network point distribution model to obtain shape parameters and posture parameters corresponding to the human body part. According to the embodiment of the invention, the trained neural network point distribution model is utilized to obtain the shape parameter and the attitude parameter corresponding to the human body part according to the plurality of key points of thehuman body part, and compared with the prior art, the problems of large calculation amount and long PDM model establishment time can be improved.

Description

technical field [0001] The present application relates to the technical field of prediction or optimization, and in particular, to a method and device for parameter inference. Background technique [0002] Point Distribution Model (PDM) is a classic parametric statistical model describing the shape of deformable objects in the field of computer vision. A typical application of PDM is to parametrically represent the shape of the face, so as to obtain the quantitative description of the geometric related information such as the scale, attitude angle, shape features, and expression of the face. The parametric representation of the shape of the face can be applied to various scenarios such as human attention detection, behavior analysis, and human-computer interaction. The shape of a face can be represented by a fixed number of coordinate points. Intuitively, PDM is to perform statistical analysis and process it into a parameter model after obtaining the representations of the...
