Abstract

Deep learning is the latest trend of machine learning and artificial intelligence research. As a new field of rapid development in the past ten years, more and more researchers pay attention to it. Convolutional neural network (CNN) model is one of the most important classical structures in deep learning model, and its performance has been gradually improved in recent years. Since it can automatically learn the feature representation of sample data, convolutional neural network has been widely used in image classification, object detection, semantic segmentation and natural language processing. This paper first analyzes the model structure of typical convolutional neural network model, which increases the depth and width of the network in order to improve its performance, analyzes the network structure that uses attention mechanism to further improve the performance of the model, and then summarizes and analyzes the current special model structure. Finally, it summarizes and discusses the application of convolutional neural network in related fields, and the future research direction is prospected.

Abstract

Head Pose Estimation (HPE) has a wide range of applications in computer vision, but still faces challenges: (1) Existing studies commonly use Euler angles or quaternions as pose labels, which may lead to discontinuity problems. (2) HPE does not effectively address regression via rotated matrices. (3) There is a low recognition rate in complex scenes, high computational requirements, etc. This paper presents an improved unconstrained HPE model to address these challenges. First, a rotation matrix form is introduced to solve the problem of unclear rotation labels. Second, a continuous 6D rotation matrix representation is used for efficient and robust direct regression. The RepVGG-A2 lightweight framework is used for feature extraction, and by adding a multi-level feature fusion module and a coordinate attention mechanism with residual connection, to improve the network's ability to perceive contextual information and pay attention to features. The model's accuracy was further improved by replacing the network activation function and improving the loss function. Experiments on the BIWI dataset 7:3 dividing the training and test sets show that the average absolute error of HPE for the proposed network model is 2.41. Trained on the dataset 300W_LP and tested on the AFLW2000 and BIWI datasets, the average absolute errors of HPE of the proposed network model are 4.34 and 3.93. The experimental results demonstrate that the improved network has better HPE performance. [ABSTRACT FROM AUTHOR]
