Embodiment Construction

[0068] A people counting method based on multi-scale mask-aware feedback convolutional neural network, comprising the following steps:

[0069] Step 1: Collect the production headcount database. The collection of the database comes from two parts, one is from video shooting equipment, such as outdoor surveillance cameras or mobile phones, etc., and the other is collected from the Internet, such as inputting key words such as "crowd" and "people" in search engines such as Baidu and Google. Search by word, collect crowd pictures, such as figure 1 shown.

[0070] Step 2: Generate training and testing samples. Annotate the collected image or video data, and generate training and test samples, which include:

[0071] Step 201: Edit the video frame obtained in step 1 into a single frame picture. Record the position of the first element in the upper left corner of the picture as the origin, and use the point coordinate x in the picture p =(g p ,h p ) mark the position of the c...

Abstract

The invention discloses a people counting method based on a multi-scale mask perception feedback convolutional neural network. The people counting method comprises the following steps: (1) searching and manufacturing a people counting database; (2) generating training and testing samples; (3) carrying out data preprocessing on samples of the training and testing set; (4) constructing a people counting deep network model; (5) sending the generated training sample into the constructed deep network model for training, and optimizing the parameters of the network through an Adam optimization method; and (6) testing the deep network model. According to the method, a people counting network is constructed by using a multi-task learning strategy, the result of mask estimation branching is fused into picture features by the network, and then a robust people counting model is obtained; according to the method, a simple fusion strategy and a multi-scale learning strategy based on hole convolution are used, so that an accurate and stable detection result is realized, and complex configuration and memory consumption in application are avoided.

Description

technical field [0001] The invention relates to the technical fields of image processing and pattern recognition, in particular to a method for counting people based on a multi-scale mask perception feedback convolutional neural network. Background technique [0002] With the advancement of urbanization and the needs of people for entertainment and work, scenes of gatherings of many people and groups have become common in many places, which has also brought about increasingly severe safety management problems. In recent years, people often hear reports of mass incidents and stampedes around the world. Therefore, how to count the number of people in public places is a crucial task. This task can help manage crowds and provide crowd density distribution data, which is convenient for comprehensively guiding the flow of crowds, making safety problems in public places controllable and preventable. Therefore, this task has important application value for public safety. [0003]...
