Detailed description of the invention
For making the purpose of the application, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, embodiments herein is described in detail. It should be noted that when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Fig. 1 is the flow chart that the present invention realizes the method for Computer Vision, as it is shown in figure 1, include:
Step 100, obtain video image image information, according to the images match information prestored, it is determined that the adjustable object in image information;
In this step, images match information includes: for video scene and/or video personnel and/or and video article carry out the matching condition information mated;
Determine that in image information, adjustable object includes:
Image information is mated with the images match information prestored, using the object that meets matching condition information in described image information as adjustable object.
It should be noted that the method obtaining the image information of video image belongs to the conventional techniques means of those skilled in the art, the protection domain being not intended to limit the present invention, repeat no more here.
Owing to image information is adjusted processing by needs, therefore the image information obtained is typically maintained in the equipment obtained in the middle of image information and display image information (video image carries out the equipment component that buffering arranges), such as, image information is saved in multipoint control unit (MCU) by video conference;
In this step, when being video personnel for images match information, mainly through the matching process of recognition of face, it is determined that be adjustable object and video personnel in video image; When being video article for images match information, then determined by the goods attribute feature of conventional goods attribute feature or artificial input, such as, adjustable object and video article in video image are determined in the attribute character of the common items such as water tumbler, phone, desk lamp, notebook, implement the known general knowledge belonging to images match those skilled in the art, repeat no more here.
Further, in video conference process, if occur rubbish or other too much article in the image information of reality, affecting the video personnel evaluation to video activity participant, therefore video article also include rubbish, medicated clothing etc.
In the present invention, it is possible to video scene and/or the images match information such as video personnel and/or video article are set up corresponding data base and stored.
The each adjustable object determined is adjusted by adjustable strategies that step 101, basis pre-set respectively.
In this step, adjustable strategies is that the adjustable object for above-mentioned each type distributes setting, specifically includes:
When adjustable object is video scene, the parameter that adjustable object carries out brightness and/or tone value and/or contrast value and/or saturation is adjusted;
When adjustable object is video personnel, the facial characteristics of adjustable object and/or the colour of skin and/or hair style and/or glasses and/or clothing is carried out denoising or replace and adjusts;
When adjustable object is video article, adjustable object is covered or the position at its place, size, definition are adjusted.
For video conference, for meeting-place scene, its adjustable strategies includes pre-setting about adjustment parameter informations such as brightness, tone value, contrast value, saturations, in conjunction with parameters such as the actual brightness of the parameter information and meeting-place that obtain image information in video image, tone value, contrast value, saturations, according to the adjustment parameter information arranged, image information adjusted corresponding numerical value; For personnel participating in the meeting, then according to pre-set to adjustable strategies such as the colour of skin, hair style, clothing, personnel participating in the meeting's image information in video image is adjusted, such as participant's hair style individual character, in adjusting according to adjustable strategies, could alternatively be comparatively ripe image, when the facial characteristics of personnel participating in the meeting includes noise, it is possible to the adjustment being sampled covering processes; Consumer's Experience that video conference image shows is affected for the wallet on article of attending a meeting, such as table, napkin etc., it is possible to pre-set adjustable strategies for carrying out obfuscation, replacement, even delete processing.
The inventive method also includes: pre-save the image information of each video personnel, when the image information of one of them or more than one video personnel being adjusted, the method also includes: according to the image information pre-saving each video personnel, it is determined that the video personnel in described image information;
According to the fine setting strategy that each video personnel pre-set are corresponding, the image information that carries out of each video personnel is adjusted.
It should be noted that fine setting strategy refers to that to different video personnel, the strategy of adjustment can be configured according to actual needs according to the corresponding adjustable strategies that each video personnel are arranged, because of referred to herein as fine setting strategy.
Below by way of specific embodiment, the inventive method being carried out clear detailed description, embodiment only for stating the present invention, is not limited to the scope that the present invention protects. Embodiment is using video conference as practical application scene, and in the applied environment of video record and net cast and Internet video, equally possible enforcement, apparatus structure that specific design arrives and processing procedure, according to the actually used adjustment carrying out non-creativeness.
During holding video conference, when the image information obtained by far-end video harvester is shown in face of the personnel participating in video conference strictly according to the facts, often there is more problem in the video image not carrying out any process; Such as, picture lighting scene is too dark, causes cannot clearly checking meeting-place picture detail; Personnel participating in the meeting thinks that self dress or image affect video conference; The article occurring in that in a jumble or be likely to affect meeting in the meeting-place of video image, these situations, in existing video conferencing system, it does not have corresponding processing method, the impact that video conference participants is caused, and often cannot be carried out concrete assessment.
