Abstract

The invention discloses an anti-sneak shot detection method based on deep learning, the steps of which are as follows: 1. Construct a deep learning target detection network; 2. Generate a training set; 3. Adopt multiple scale frame methods to detect the same sneak shot behavior in a picture Mark; 4. Train the deep learning network; 5. Detect candid behavior; 6. Enhance the image without candid behavior; 7. Re-detect the image after feature enhancement. The invention overcomes the problem of low detection accuracy caused by diversification of candid photography behaviors and actions by adopting a variety of scale frame methods when marking the data set, constructs a deep learning network and performs image enhancement processing on the humanoid area, ensuring In order to achieve real-time effects in the detection of candid behavior in surveillance video, it has a high accuracy rate.

Description

technical field [0001] The invention belongs to the technical field of image processing, and further relates to a deep learning-based anti-sneak shooting detection method in the technical field of target detection. The invention can detect in real time the sneak shooting behavior of people captured in the video surveillance. Background technique [0002] Anti-surveillance detection in video surveillance is a very necessary behavior in many confidential institutions and units, which can prevent the internal confidential information of institutions or units from leaking to the outside world. However, in practice, it is time-consuming and labor-intensive to manually detect sneak shots in video surveillance, and it is difficult to achieve real-time detection. In order to solve the above problems, people usually design target detection methods, and use computers to detect sneak shots in video surveillance. [0003] Yulinian Electronics Nantong Co., Ltd. provides a computer visi...
