Abstract: Systems and methods of computer-assisted programming, including: storing, on a computer memory, a program code, displaying the program code, receiving, from a user, a mark of a location in the displayed program code, producing a list of selectable program elements that are valid for insertion into the program code at the marked location, in accordance with one or more rules of a programming language, receiving, from the user, a selection of at least one program element from the list of selectable program elements, inserting the at least one selected program element into said program code in the computer memory, at a location corresponding to the marked location received from the user, and preventing the user from inserting a program element into the stored program code in any way that is devoid of selection of at least one selectable program element from the list of selectable valid program elements.

Abstract: Disclosed a method for tracking 3-dimensional objects, or some of these objects' features, using range imaging for depth-mapping merely a few points on the surface area of each object, mapping them onto a geometrical 3-dimensional model, finding the object's pose, and deducing the spatial positions of the object's features, including those not captured by the range imaging.

Abstract: Disclosed a method for stereoscopic display using a color parallax barrier consisting of interleaved bands of color filters, allowing left and right eyes to see different color components of the same screen pixels through different color filters, and having left and right images displayed together on screen by combining in same screen pixel color components from left image visible to left eye through color filter and different color components from right image visible to right eye through different color filter. Also disclosed methods for a color parallax barrier that can be activated or inactivated, allowing switching between full-resolution two-dimensional display and three-dimensional stereoscopic display.

Abstract: A method for rapid color keying of color video images using individual color component Look-Up-Tables (LUTs), assigned, storing, and used for retrieving, unique sets of predetermined values, for calculating pixel transparency values of input image pixels of a color video input image, for rapidly generating output image pixels of a color video output image including selectively keyed out or transparent pixels. Pre-determined values of the individual color component LUTs are positive integer values, positive non-integer values, and zero. Particular sets of pre-determined values account for high tolerance to changes in lighting, high tolerance of color brightness, and/or, for mixing colors such as for generating smooth edges, of input image pixels of the color video input image.
