Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not limited to the present embodiment.
A kind of video conferencing system, it comprises a camera head, object detection masking device, controller, picture coding device and dispensing device by a kind of video masking system.Concrete apparatus function can be made up of following mode.
Camera head, gathers for the content to video conference, and described video conference flow data is sent to object detection masking device;
Object detection masking device, cover processing for the Private Parts image that needs are covered, in the time that Private Parts image is fixed blind region, user manually or automatically inputted the parameter coordinate figure of the fixed boundary of shaded areas by system, and carry out shelter reason, the parameter value of input and meeting video flowing are offered to controller simultaneously; In the time of image that Private Parts image is moving region, object detection masking device is by signal processing, extraction needs the feature of image in the moving region of crested, complete after image characteristics extraction, determine the border of image in moving region, and the image in moving region is covered to processing, send to controller by the image feature data of extraction and by the meeting video flowing after covering simultaneously.
Object detection masking device, further, physical detection masking device, can be included in controller, for an interior module of controller, by controller is merged, the also independent standalone module outside controller.This object detection masking device, can be according to the different modes of covering, sub-category processing.The masking methods that this device is realized comprises, fixed area is covered or image to moving region, processes, and specifically can cover along the edge tracking dynamic image of the image of moving region.Every kind of masking methods can be configured the screening effect of image, can be configured to shielded area to be fixed color, fixing picture covering, image mosaicked field is carried out in shielded area.
Cover processing and allow user to be configured selection to shaded areas, can select to cover with rectangle, square, circular, oval, irregular multiple spot enclosing region, and allow user's setting to cover color, effect, the transparency of shaded areas.After user's setting completed shaded areas, controller can be converted into setting area the resolution of camera review, with the mode of figure mask and video camera frame by frame image compare, image in mask region just carries out image operation according to user configured color, transparency, and then replaces the image that needs shaded areas.
Controller receives and arranges and carry out the streamed switching of data and control for parameter.Controller also can fusion detects the function of masking device.Object detection masking device and controller mutual, can complete the controller inside after fusion.
Picture coding device, encodes for the meeting video flowing to after covering, and sends dispensing device to by controller.
Dispensing device, for receiving the meeting video stream data after send by controller encoded, and sends these data.
Describedly will cover video flowing after treatment and encode, further comprise: to the image of crested, adopt the coded system identical with covering meeting video flowing after treatment, and data to the crested image after coding, be encrypted, and store.
Cover if desired when crested region loses, or need to, in the time that certain limit is not covered transmission, can, by input secret key decryption, complete the recovery to shaded areas encrypted image, and send dispensing device to because of other.
Described object checks masking device, further comprises, the region that controller covers setting is converted into the resolution of camera review, according to parameters such as user configured color, transparencies, arranges and covers figure, replaces shaded areas image.
The present invention can also be achieved by method.Realize a method for image masking, it specifically can comprise the steps,
S1, meeting video stream data is received,
S2, the privacy area that needs are covered cover processing, when the privacy area covering when need is fixed blind region, user manually arranges or is automatically inputted by system the parameter coordinate figure of the fixed boundary of shaded areas, and carry out shelter reason, the parameter of input and meeting video flowing are offered to controller simultaneously; When image that the privacy area covering when need is moving region, video conference stream is carried out to signal processing, extract the feature of the image of moving region, complete after image characteristics extraction, determine the border of image in moving region, and the image of moving region is covered to processing, the image feature data of extraction and meeting video flowing are sent to controller simultaneously; Described cover to be treated to adopt the privacy area that the mode of rectangle, circle, ellipse or User Defined image is covered need to replace.
S3, to covering the meeting video flowing after treatment processing of encoding, and send to dispensing device by controller.
The step of S3 further comprises, to after covering meeting video flowing after treatment and encoding and process, to the processing of encode of the image after covering, both coded systems are identical, the view data after encoding are encrypted simultaneously.
If S4 request is decrypted processing to the view data of covering, cover recovery.Described cover to revert to veil is replaced with to initial image.
The described processing of covering allows user to be configured selection to shaded areas, can select to cover with rectangle, square, circular, oval, irregular multiple spot enclosing region, and allow user's setting to cover color, effect, the transparency of shaded areas.After user's setting completed shaded areas, controller can be converted into setting area the resolution of camera review, with the mode of figure mask and video camera frame by frame image compare, image in mask region just carries out image operation according to parameters such as user configured color, transparencies, and then replaces the image that needs shaded areas.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
