The present invention relates to an object recognition model establishment method and an object recognition method. The object recognition model establishment method includes the following steps that: an input image is obtained; the depth feature of the input image is extracted; structuralization modeling is performed for an object in the input
image based on a random field structure model, so that the structuralized expression of the object can be obtained; and structural parameters are learned through using a gradient back-propagation
algorithm based on the structuralized expression of the object, and a gradient is calculated, and learning and training are performed through suing a
stochastic gradient descent algorithm, so that an object recognition model can be obtained. With the object recognition model establishment method and the object recognition method provided by the embodiments of the invention adopted, the technical problems of complex elastic deformation, attitude change and visual change of an object in a
visual task can be solved, and the structural expression ability of a deep
network model is improved. The object recognition model establishment method and the object recognition method provided by the embodiments of the present invention can be applied to a plurality of fields involving object recognition, such as object classification,
object detection and face recognition fields.
