The image recognition system can classify the pictures of the people, the same participants can be classified uniformly, the pictures of the participants can be analyzed according to the time lines of the people, the walking paths of the participants can be tracked, the interested topics of the participants can be analyzed, the interested people can specifically select a conference speech mode according to the interests of the participants, the conference interest degree of the participants is improved, and the conference effect is improved.

As a preferred embodiment, the image and picture processing unit comprises picture sharpness processing, picture resolution processing, picture saturation processing, and picture sound processing.

In a preferred embodiment, the picture sound processing includes picture volume processing, picture tone processing, picture noise processing, and picture background sound processing.

The image picture processed by the image picture processing unit enables the image picture to be in proper definition, resolution and saturation, and excellent image expression performance is provided for an image observer. The image picture after the sound processing can increase the lower speech sound in the picture, reduce the higher speech sound, make the sound of the picture in the average range, and weaken the noise in the picture, make the main sound in the picture clearer. Under the appropriate background sound, the emotion of the speaker can be exerted to the maximum extent, but when the background sound is inappropriate, the speaker can be interfered to speak, and the conference speaking effect is reduced. When the picture is processed, the background sound is adjusted to optimize the speaking effect of the speaker.

In a preferred embodiment, the image frame storage system comprises image frame compression, image frame storage and image frame format conversion.

After the image is processed, the problem that the image can not be opened on different equipment can occur, or the quality of the opened image is poor due to the incompatibility of the image formats, the sound is not matched with the image, the watching experience of a viewer is reduced, the conversion of a plurality of different image formats can be realized after the image is processed by the image processing technology, and the operation is simple and convenient.

As a preferred embodiment, the image frame capturing system includes a still image frame capturing unit and a moving image frame capturing unit.

Compared with the prior art, the invention has the following beneficial effects:

(1) The picture processing technology applied to meeting scenes enables pictures of the same scene to adopt the same picture processing technology by classifying pictures of different collected scenes, realizes batch processing of the pictures of the same scene, and improves the picture processing efficiency.
