The invention discloses a video monitoring method, system and device and a computer readable storage medium. The method comprises the steps: obtaining a monitoring video; detecting a feature region image in the monitoring video; encoding and quantizing the feature region image to obtain feature region quantized data, and backing up the feature region quantized data to obtain backup feature regionquantized data; encrypting the backup feature region quantized data to obtain encrypted feature region quantized data; packaging the encrypted feature region quantized data and the feature region coordinates of the feature region image to obtain a packaging result; tampering the feature region quantized data to obtain tampered feature region quantized data, and taking the tampered feature region quantized data as a quantization result of the feature region image to obtain a quantization result of the monitoring video; carrying out entropy coding on the quantization result of the monitoring video to obtain a coding result; and carrying out parallel code transmission on the coding result and the packaging result. Thus, the applicability is high.
Description
technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a video monitoring method, system, device and computer-readable storage medium. Background technique [0002] Digital technology and high-definition technology have comprehensively improved the clarity of images, and monitoring equipment has also become popular, and has been widely used in various fields. Correspondingly, there has been a problem that monitoring equipment violates user privacy. [0003] In order to solve this problem, an existing method is to directly fill the characteristic image collected by the monitoring equipment with black to hide the characteristic image. However, after the feature image is filled with black, it is difficult to restore the feature image, and the black color will also affect the user experience, making the applicability of the existing methods poor. [0004] To sum up, how to provide a monitoring device with go...
