Embodiment Construction

[0013] figure 1 An image processing system 100 designed in accordance with the present invention is illustrated. According to one aspect of the present invention, the image processing system 100 makes one or Multiple users can join an image or image sequence, such as a video sequence or video game sequence. The actor to be replaced can be selected by the user from the image sequence, and can also be predetermined or dynamically determined. In one variation, the image processing system 100 may analyze the input image sequence and rank the actors included in the input image sequence according to, for example, the number of frames in which the actors appear or the number of frames in which the actors have close-up shots.

[0014] First, the raw image sequence is analyzed and, for each frame, various parameters associated with the actor to be replaced are estimated, such as the actor's head pose, facial expression, and lighting characteristics. In addition, a static model of th...

Abstract

An image processing system is disclosed that allows a user to participate in a given content selection or to substitute any of the actors or characters in the content selection. A user can modify an image by replacing an image of an actor with an image of the corresponding user (or a selected third party). Various parameters associated with the actor to be replaced are estimated for each frame. A static model is obtained of the user (or the selected third party). A face synthesis technique modifies the user model according to the estimated parameters associated with the selected actor. A video integration stage superimposes the modified user model over the actor in the original image sequence to produce an output video sequence containing the user (or selected third party) in the position of the original actor.

Description

technical field [0001] The present invention relates to image processing techniques, and in particular to methods and apparatus for modifying a sequence of images so that a user can participate in the sequence of images. Background technique [0002] The consumer market offers a wide variety of media and entertainment options. For example, there are a variety of media players that support various media formats, bringing users an almost unlimited amount of media content. In addition, a variety of video game systems are available that support a variety of formats, allowing users to play an almost unlimited number of video games. However, many users may quickly lose interest in such traditional media and entertainment options. [0003] While there may be a large number of content options, a given content selection typically has a fixed cast or animated character. As a result, many users often lose interest in viewing the cast or character lineup in a given content selection,...
