Abstract
A video masking processing method and a video masking processing apparatus using the same are provided. The video masking processing method photographs frames constituting a video, detects at least one masking area to be masked in the photographed frames, masks an image in the detected at least one masking area, inserts masking information including information on the masking into the photographed frame, and stores the frame which has undergone the masking and has the masking information inserted thereinto. Therefore, since images related to personal information in a photographed video are masked, a user does not infringe others' privacy in a video normally photographed by a CCTV or a dashboard camera.
Claims4
A video masking processing method, comprising:
- detecting a masking area to be masked in a frame constituting a video;
- masking an image in the detected masking area;
- inserting masking information on the masked image into a predetermined pixel area of the frame;
- storing the frame comprising the inserted masking information;
- displaying a vehicle plate number or a human face included in the video using the inserted masking information;
- and
- when one of the vehicle plate number or human face is selected, reproducing a frame of the video that includes the selected vehicle plate number or human face,
- wherein the masking information comprises
- information on a number of masking areas in the frame, and
- masking area information corresponding to the number of the masking areas,
- wherein the masking area information comprises an identifier of a corresponding masking area, information on a masking technique code applied to the corresponding masking area, coordinates information of a left upper point of the corresponding masking area, and coordinates information of a right lower point of the corresponding masking area, and
- wherein the image in the detected masking area is masked using a different key according to an object type of the image.
A video masking processing apparatus, comprising:
- a processing unit configured to
- detect a masking area to be masked in a frame constituting a video,
- mask an image in the detected masking area, and
- insert masking information on the masked image into a predetermined pixel area of the frame;
- and
- a storage unit configured to store the frame comprising the inserted masking information,
- wherein the masking information comprises
- information on a number of masking areas in the frame, and
- masking area information corresponding to the number of the masking areas,
- wherein the masking area information comprises an identifier of a corresponding masking area, information on a masking technique code applied to the corresponding masking area, coordinates information of a left upper point of the corresponding masking area, and coordinates information of a right lower point of the corresponding masking area, and
- wherein the image in the detected masking area is masked using a different key according to an object type of the image.
