Abstract: The present invention discloses an interactive presentation system which allows a presenter to perform a presentation while having various interactions directly with presentation material images in real time through a gesture or/and voice. The interactive presentation system comprises: an active infrared camera; a command recognition system connected to the active infrared camera; and an image synthesis system connected to the active infrared camera and the command recognition system. The presentation system may further comprises a stereo camera set for properly synthesizing a presenter in a 3D image and a 3D motion system. By this configuration, it is possible to embody an interactive presentation system in which a command through a presenter's gesture or voice is processed in real time and the image of the presenter is synthesized in a presentation material screen in real time, and accordingly the audiovisual effect is maximized.

Abstract: A method for obtaining a glassless image is disclosed. The image processing method comprises the steps of (a) receiving an RGB color frontal facial image; (b) extracting candidates of eye regions from the received RGB color frontal facial image; (c) determining an exact eye region out of the candidates and normalizing the received RGB color frontal facial image; (d) extracting a glasses frame region by using color information contained in the received RGB color frontal facial image and edge information of a glasses frame; (e) performing an RGB-HSI transformation on the normalized frontal facial image; (f) generating H?, S?, and I? glassless compensated images; (g) obtaining R?, G?, and B? compensated images by performing an HSI-RGB transformation on the H?, S?, and I? glassless compensated images; and (h) creating a glassless final color facial image on the basis of the R?, G?, and B? compensated images.

Abstract: A stereo disparity between a reference image and a search image for a reference pixel in the reference image is determined by (a) calculating a similarity measure between a reference window including a set of pixels centering on the reference pixel and each of a group of search windows in the search image which is of a same shape with the reference window and displaced from the reference window within a predetermined search range, wherein a matching pixel count, which is the number of pixels in the reference window which are similar in intensity to corresponding pixels in a search window, is used as the similarity measure between the reference window and the search window; and (b) determining a displacement between the reference window and a search window which yields a largest similarity measure as the stereo disparity for the reference pixel.

Abstract: The invention provides a teleconference method of sharing a working space between at least two terminals remotely interconnected through a communication network. The method includes the steps of: a) setting one of the terminals as a teleconference server terminal and the rest of terminals as client terminals; b) connecting the client terminals to the teleconference server terminal through the communication network; c) producing identifier mouse pointers by using identifiers of the participants and mouse pointer coordinates of the terminals at the teleconference server terminal; d) displaying the identifier mouse pointers on a screen of the teleconference server terminal; e) providing a shared window to each screen of the client terminals for displaying a clone of a screen of the teleconference server terminal; and f) at the teleconference server terminal, performing a mouse action based on a mouse event generated from each of the terminals.
