Abstract

The invention discloses a pedestrian detection method and system based on dynamic grouping convolution, belongs to the technical field of neural networks, and aims to solve the technical problem of how to realize pedestrian detection by utilizing grouping convolution and effectively improve the pedestrian detection efficiency. A target detection network architecture is constructed by using packet convolution, and initial training is completed while an original neural network structure is reserved; calculating scores of the input channel and the output channel by using a significance score generator, and sorting according to a sequence from high to low; setting a threshold value, and screening an input channel corresponding to the output channel; replacing the last 1 * 1 point-by-point convolutional layer in each inverted residual block by using a channel selector; training the target detection network architecture again by using the pedestrian data to obtain a reasoning model; and deploying the inference model at a side end, and identifying and judging a target acquired in real time.

Description

technical field [0001] The invention relates to the technical field of neural networks, in particular to a pedestrian detection method and system based on dynamic grouping convolution. Background technique [0002] In recent years, a variety of target detection networks have emerged in the field of deep learning, which have excellent performance in many aspects such as model size, inference speed, and recognition accuracy. Object detection is mostly used in the field of video surveillance and tracking. With the development of edge computing, mobile devices are usually required to have certain intelligent detection capabilities, which are limited by the storage resources and computing resources of the device. Inference speed and detection accuracy. Deeper and wider deep convolutional neural networks can achieve better performance, which leads to the design of a large number of huge and complex models. In order to reduce the complexity of the model and ensure the accuracy of...
