Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0025] Such as figure 2 As shown, the specific embodiment of the present invention is: provide a kind of human face automatic labeling method, comprise the steps:

[0026] Step 100: face detection, that is: detect the face from the intercepted video, obtain the face picture set, then filter out the face picture set, and at the same time, obtain the HSV color histogram difference value of the adjacent frame of picture, using The lens edge detection algorithm of the spatial color histogram performs lens segmentation; for the faces from adjacent frames, detect the corner points in the target area of ​​the first frame, and use the local matching method to extend these corner points to the next frame, and Perform corresponding updates, and count the number of matches, and proceed accordingly to obtain the face sequence according to the threshold of t...

Abstract

The invention relates to a face automatic labeling method and a face automatic labeling system. Firstly, faces are detected from a captured video, a face image set is acquired, then the face image set is filtered, an HSV (Hue, Saturation, Value) color histogram difference value of an image of an adjacent frame is simultaneously acquired, shot segmentation is carried out by adopting a spatial color histogram shot edge detecting algorithm, angular points in a target region of a first frame are detected for the faces from the adjacent frame, the angular points are deferred to a next frame by using a local matching method, corresponding updating is carried out, a matched number is subjected to statistics, and according to a threshold value of the matched number, the operation is sequentially carried out to acquire face sequences; then speakers and unspeaking people are detected by a lip motion detection module according to lip motion of the speakers in the face sequences and the speakers, talk contents and talk time are fused to be labeled; and finally, the faces on each sequence are read in and are gradually positioned, then affine transformation is carried out according to a positioning result and pixel gray values in a round region with a fixed size near a transformed feature point are extracted to be used as features of the faces. The face automatic labeling method and the face automatic labeling system which are disclosed by the invention are convenient to use and have high accuracy.

Description

technical field [0001] The present invention relates to a method and system for human face labeling, in particular to a method and system for automatic and accurate labeling of human faces. Background technique [0002] Video face annotation is a kind of video information mining. The existing and common technology is to use manual annotation. The annotation process is as follows: figure 1 . In the process of traditional manual labeling, the efficiency is low, time-consuming and labor-intensive. And due to human differences may lead to inconsistent labeling before and after. The existing technology of automatic video face labeling is basically in the experimental research stage, and there is no effective, stable and accurate automatic labeling system. Contents of the invention [0003] The technical problem to be solved by the present invention is to construct a method and system for automatic face labeling to overcome the technical problem that the prior art does not ha...
