Embodiment 1

[0048] figure 1 A schematic flow chart of the privacy protection method provided in Embodiment 1 of the present invention; figure 1 As shown, the present embodiment provides a privacy protection method, the method is a video-based privacy protection method, including:

[0049] In step 101, a reference face is obtained, and the reference face is a face used for comparison.

[0050] Specifically, in practical applications, for example, during public security investigation, the face of the criminal suspect needs to be disclosed to the public so that the public can provide clues to the suspect. At this time, the criminal suspect can be regarded as a person of concern, The face of a person is the reference face, and the selection of the reference face is for comparison (matching) processing in the subsequent steps.

[0051] Step 102, scan the video frame by frame, and obtain faces to be processed according to a face recognition detection algorithm, and the faces to be processed a...

Embodiment 2

[0058] This embodiment is a supplementary description based on the above embodiments.

[0059] figure 2 A schematic flow diagram of the privacy protection method provided in Embodiment 2 of the present invention; as figure 2 As shown, the present embodiment provides a privacy protection method, the method is a video-based privacy protection method, including:

[0060] Step 2011, acquire the current face image through the camera device or receive the selected face image as the current face image;

[0061] Specifically, the current face image can be obtained by taking pictures with a mobile terminal or a computer, or can be obtained from a face database.

[0062] Step 2012, performing face recognition on the current face image to obtain the face area;

[0063] The current face image is processed through the face recognition algorithm to obtain the face area, so that the face area can be processed later.

[0064] Step 2013, perform face extraction on the face area to obtain a...

Embodiment 3

[0076] image 3 A schematic flow chart of the privacy protection method provided in Embodiment 3 of the present invention; image 3 As shown, this embodiment provides a privacy protection method, the method is a picture-based privacy protection method, including:

[0077] Step 301, acquiring a reference face, which is a face used for comparison;

[0078] Further, this step specifically includes:

[0079] Obtaining a picture of a human face to be extracted, wherein the picture of a human face to be extracted contains a reference human face;

[0080] Face extraction is performed on the image to be extracted to obtain a reference face.

[0081] Specifically, the picture of the human face to be extracted can be obtained by taking pictures with a mobile terminal or a computer, or can be obtained from a human face database.

[0082] Further, this step specifically includes: acquiring a reference face from a face database.

[0083] Specifically, the reference face is directly ob...

Abstract

The invention provides a privacy protecting method and a privacy protecting device, wherein the privacy protecting method comprises the steps of acquiring a reference face, performing frame-to-frame scanning on a video, and acquiring a to-be-processed face according to a face identification detecting algorithm; performing matching between the reference face and the to-be-processed face, and performing mosaic processing on the to-be-processed face which does not match the reference face in the video; performing compression storage of the processed video and publishing the processed video. According to the privacy protecting method and the privacy protecting device with the video processing manner, mosaic processing can be performed on the faces of non-focused personnel in the video, thereby protecting privacy of the non-focused personnel. The privacy protecting method and the privacy protecting device can be utilized for realizing privacy protection at places where face identification is utilized, such as schools, hospitals and public places.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a privacy protection method and device. Background technique [0002] In some special application fields, it is necessary to occlude (or add mosaics) to the face in the dynamic image. For example, in order to protect the privacy of the interviewee in the news, the face image of the interviewee needs to be occluded, such as the court For the needs of the case, judicial organs such as the procuratorate and the public security bureau often show the video recordings of witnesses testifying. In order to protect the safety of witnesses and other related personnel, the recorded videos must be processed, such as using mosaics to block faces or face masks. Obfuscation and more. For the public security department, in order to meet the needs of work, it is necessary to disclose the surveillance video including the suspect, so as to help the public provide important information to so...
