(EN) The invention is applied to the technical field of image detection and provides a method and a device for face tracking. The method comprises the steps of acquiring an image position of a face detection box in a previous image frame; locating a region which is the same as the image position in a current image frame; carrying out face alignment between an image in the region located in the current image frame and a front template of a face in the face detection box to acquire characteristic point positions of the face in a current image; determining the face detection box in the current image frame according to the acquired characteristic point positions. When face tracking is carried out on a video image, overall situation is not needed for each frame of image in a video, the calculation quantity for face tracking in the video is reduced, the processing efficiency is improved and the influence degree of video definition for processing is reduced.
(ZH) 本发明适用于图像检测技术领域,提供了一种人脸追踪的方法及装置,包括:获取人脸检测框在上一图像帧中的图像位置;在当前图像帧中,定位出相同所述图像位置的区域;将所述当前图像帧中定位出的区域内的图像与所述人脸检测框中人脸的正面模板进行人脸对齐,获取所述当前图像中所述人脸的特征点位置;根据获取到的所述特征点位置,在所述当前图像帧中确定出人脸检测框。本发明对视频图像进行人脸追踪时不需要对视频中每帧图像都进行全局检测,减少了对视频人脸追踪的运算量,提高了处理效率,降低了视频清晰度对处理的影响程度。
