Image processing method and device for protecting privacy, terminal and storage medium

Abstract

The invention discloses an image processing method for protecting privacy. The method comprises the following steps: S1, acquiring image information; S2, converting the image information into an image data matrix; S3, performing convolution operation on the image data matrix and a group of mask matrices to obtain a group of new data matrices; and S4, re-coding the obtained new data matrices into a group of new arrays. Compared with the prior art, the image processing method for protecting privacy provided by the invention has the advantages that a series of mask matrices are designed, and the original image matrix and the mask matrices are subjected to convolution operation, so that a series of new matrices are obtained; in the newly generated matrices, the visual information of the original image is recombined, and the original coding mode is destroyed, so that an observer cannot directly obtain the visual information, and it is ensured that privacy cannot be leaked from the source.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, terminal and storage medium for protecting privacy. Background technique [0002] Vision is one of the ways humans perceive the world, and people's visual senses come from the eyes. The human eye focuses light on the retina through the lens, and then uses the photoreceptor cells on the retina to obtain information such as color and intensity. [0003] After the emergence of computers, digital cameras and other equipment, people can digitize visual information. The photosensitive device in a digital camera can simulate the working method of the retina and convert photons into electrons to generate digital photos. Image is a coding method of visual information, its purpose is to facilitate human visual perception, but it also brings the risk of privacy exposure. At present, cameras are widely used in various fields, bringing g...

AI Technical Summary

Problems solved by technology

The image or video data collected by the camera is generally not encrypted, and it is easy to be stolen, causing a great privacy risk

Even if some devices are encrypted during network transmission, there is no guarantee that they will not be cracked
