Adjustment Of Perceived Roundness In Stereoscopic Image Of A Head

摘要

In telecommunication video calling and videoconferencing systems, it is strongly desirable for remote observers to interact with natural gaze cues. In natural gaze interaction, the camera for a source observer appears to be co-located in the eye region of a destination observer image and vice versa. The appearance of camera co-location is achieved for stereoscopic camera pair that are placed either side of an autostereoscopic 3D display. Such cameras typically provide stereoscopic images that have disparity distributions that provide unnatural perceived head roundness. The present embodiments achieve perceived head roundness that is closer to that expected in natural face to face interaction by modification of perceived local depth in detected regions of the head.

主权项

1. A method of adjusting perceived roundness in a stereoscopic pair of images that image a head, the method comprising processing one or each image by the following steps:
identifying at least one region of the image that images a part of the head; and locally transforming the at least one region in a manner that adjusts the perceived local depth in accordance with expected local depth in the imaged part of the head.
