Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] as attached Figure 7 As shown, it is a flow chart of the facial expression and posture dual-modal fusion expression recognition method based on deep learning, which specifically includes the following steps:

[0040] 1. Establish a face-posture dual-modal expression database;

[0041] RAF-DB dataset: This dataset downloads more than 30,000 images from the Filckr image social network using keywords related to expressions, and invites 315 volunteers who have received expression-related knowledge training to annotate these images. The experiment uses 12271 pictures given in the data set as the training set and 3068 pictures as the test set.

[0042] FER2013 data set: The main source of this data set is downloaded through the keyword search of Google Images, so it is closer to the facial expressions under natural conditions. At the same time, the samples are ver...

Abstract

The invention belongs to the technical field of image recognition, and particularly relates to a facial expression and posture bimodal fusion expression recognition method based on deep learning. Themethod comprises the following steps of establishing an image database in a natural environment, and carrying out preprocessing and enhancement processing on an obtained image; proposing an SE-GoogleNet network to carry out feature extraction on the processed data image; selecting a convolutional part of a Caffemodel of the GoogleNet model based on action classification to directly carry out knowledge migration training; and inputting the two pre-trained convolutional neural networks into an SPP layer for feature fusion, and finally sending the fused convolutional neural networks into an LSTMto realize final classification of bimodal expression recognition. According to the present invention, an LSTM model based on face and limb dual-channel feature fusion is designed, the pyramid poolingis used, and then the size matching problem during feature fusion is solved; and in combination with transfer learning, the model can realize recognition of bimodal expressions under the condition offewer databases, so that the adaptability of the model to various natural environments is improved, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to a facial expression and posture dual-mode fusion expression recognition method based on deep learning. Background technique [0002] There are three basic forms of expression of emotion: expression, voice and language. Due to the unique non-contact, universality and authenticity of expressions, it can best reflect the true emotions of human beings in real life. Therefore, through the recognition of facial expressions, intelligent human-computer interaction and the prediction of one's own emotional fluctuations can be effectively realized. Expressions are divided into two categories: facial expressions and gesture expressions. Early research on facial expression recognition was difficult and progress was slow. With the outstanding achievements of deep learning in the field of computer vision in recent years. Deep learning structures and theories were quic...
