Patent number: 7221809Abstract: A method of automatically recognizing a human face includes developing a three-dimensional model of a face; and generating a number of two-dimensional images based on the three-dimensional model. The generated two-dimensional images are then enrolled in a database and searched against an input image to identifying the face of the input image.Type: GrantFiled: December 17, 2002Date of Patent: May 22, 2007Assignee: Genex Technologies, Inc.Inventor: Z.

Patent number: 7099732Abstract: An intra-oral imaging system includes an optical conduit, a light source generating light rays, at least a portion of which are transmitted through the optical conduit to illuminate a dental surface, a device for converting the light rays into radiation illumination with spatially varying wavelengths prior to illuminating the dental surface, a reflector that directs the light rays from the light source to a selected point; and an imager for receiving the light rays when the light rays are reflected from the dental surface.Type: GrantFiled: September 2, 2003Date of Patent: August 29, 2006Assignee: Genex Technologies, Inc.Inventor: Z.

Patent number: 7098872Abstract: A process and system for interactively displaying large (more than 1 million voxels) volumetric 3D images utilizing a sequence of helical slices of a 3D data set to generate a series of 2D images on a reflective surface of a light modulator. The series of 2D images generated on the light modulator are projected into a volumetric 3D-space display using an illumination light source and projection optics. Voxels in 3D space are illuminated for each 2D projected image, each voxel being located at its corresponding spatial location. A pulse from a wireless pulsed laser pointer forms a 3D bright voxel within the display volume. The pulse signal is synchronized with the rotating helix, and the orientation of the pointer and the phase of the pulse are controlled by the user to specify a 3D point in 3D space. A wireless receiver provides six degree-of-freedom (DOF) position of the spatial location of the pointer, as well as the phase signal.Type: GrantFiled: October 12, 2004Date of Patent: August 29, 2006Assignee: Genex Technologies, Inc.Inventor: Zheng J Geng

Patent number: 6937348Abstract: A three-dimensional imaging method and system illuminates an object to be imaged with a light pattern that is formed from two or more light sub-patterns. The sub-patterns can each encompass the visible light spectrum or can be spatially varying intensity sub-patterns that each correspond to a red, green, or blue component. The light pattern is generated by a slotted planar member or an optical filter.Type: GrantFiled: April 28, 2003Date of Patent: August 30, 2005Assignee: Genex Technologies, Inc.Inventor: Z. Jason Geng

Patent number: 6600168Abstract: A high-speed three-dimensional imaging system and method projects a spatially varying intensity pattern onto an object or scene to be imaged using a laser light source in conjunction with a scanner. The pattern varies in intensity with respect to the projection angle. A pixel intensity ratio is calculated based on the intensity information of an image pair that is illuminated by two different patterns, thereby establishing a one-to-one correspondence between pixel intensity ratio and the projection angle.Type: GrantFiled: February 5, 2001Date of Patent: July 29, 2003Assignee: Genex Technologies, Inc.Inventor: Zheng J. Geng

Patent number: 6594539Abstract: An intra-oral imaging system that produces images of a dental surface includes a probe that contains an optical conduit for transmitting light with spatially varying wavelengths for illuminating a dental surface and a camera for receiving light rays reflected from the dental surface. The invention also includes a concave reflector used in conjunction with the probe to increase the field-of-view of the camera, allowing optical coverage of the entire surface of a tooth in a single image.Type: GrantFiled: July 14, 2000Date of Patent: July 15, 2003Assignee: Genex Technologies, Inc.Inventor: Z.

Publication number: 20010015751Abstract: An omnidirectional imaging apparatus obtains images over an entire hemispherical field and uses a mapping matrix to define a relationship between pixels in a user-defined perspective or panoramic viewing window and pixel locations on the original omnidirectional image. This allows the computation of non-distorted images in real-time without relying on complex high-order non-linear equations.Type: ApplicationFiled: March 29, 2001Publication date: August 23, 2001Applicant: Genex Technologies, Inc.Inventor: Zheng J.
