摘要： A method for use with a stream of images defining a video. The method includes the steps of periodically conducting a face finding operation on an image in the stream. In respect to the last image in the stream preceding the image in which one or more faces was found, a tracker based upon wavelet decomposition is used to find a face for each face found in the last image for which no counterpart was found in the image.
摘要翻译：一种与定义视频的图像流一起使用的方法。该方法包括对流中的图像周期性进行面部查找操作的步骤。对于在其中找到一个或多个面部的图像之前的流中的最后一个图像，使用基于小波分解的跟踪器来找到在图像中找到的每个面部的面部，其中在图像中没有找到对应物。

摘要： The method includes a dictionary including a target collection defined by images that are known with a defined level of certainty to include a subject and an imposter collection defined by images of individuals other than the subject. In the method, images of an area are captured over a period of time. In respect of each image: a matching calculation is carried out, based upon a comparison of the image captured with the images in the dictionary to result in a measure of confidence that the subject is in the area; and an inference determination is made to replace one of the target collection images with a further image that is known with the defined level of certainty, the determination being a function of the measure of confidence resultant from the captured image, the measure resultant from one or more previously captured images and the associated capture times.
