Embodiment Construction

[0045] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0046] The most critical idea of ​​the present invention is: pre-process the image at the front end of the camera, blur other parts except the face, and then upload it to the cloud server. Even if the image data is intercepted after being uploaded to the network, the privacy of the user is also obtained. protected.

[0047] Please refer to figure 1 , Embodiment 1 of the present invention provides a method for automatically blurring body parts, including the following steps:

[0048] S1: Acquire an original image, and perform median filtering on the original image to remove image noise, and obtain a first image;

[0049] S2: converting the first image from RGB space to YCbCr space to obtain a second image;

[0050] S3: Setting a Y component in the second image...

Abstract

The invention discloses a method and system to automatically blur a body part. The method comprises the steps of obtaining an original image, performing median filtering for the original image, removing image noises and obtaining a first image; converting the first image from a RGB space to a YCbCr space, and obtaining a second image; extracting a Y component from the second image as a background model; calculating the difference between a pixel value in the second image and a pixel value in the background model of the Y component, obtaining a mask, performing AND operation with the first image, and obtaining a first image foreground region; and detecting and recognizing a user face region on the first image foreground region, and blurring the region outside the user face region. In this way, the invention can recognize a user identity in a local video in real time, blur the body of a particular user, and protect privacy in real time before video data are uploaded to a cloud server.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and system for automatically blurring body parts. Background technique [0002] As the life concept of smart home becomes more and more popular, more and more people pay attention to smart home security equipment. More and more families choose to install surveillance cameras at home and transmit images to users' mobile phones through the network. And when the user is at home, the camera is always monitoring the user's every move. How to ensure the user's privacy and security, and how to ensure that the image information is not leaked to the network has become a problem that users are more concerned about. [0003] The current home surveillance cameras are relatively close to the technology. For example, after face recognition, the lens is zoomed in and zoomed in, so that only the face can be seen. The disadvantage is that body parts will still be uploaded when the camera...
