Solving a problem with the aid of a computer involves the construction and execution of a program described by a linear piece of text. First, the problem-solver (programmer) translates his problem into a procedural solution embodied in a static program text, written in a programming language. Then a computer is caused to perform a dynamic sequence of(More)
A graphic data organization was designed that allows for fast access to an arbitrarily large data base. The graphic data is organized by clustering into successively larger spheres. The derived tree structure provides for multilevel descriptions of objects that allow for display of only the amount of detail that can be resolved on the display, in addition(More)
Gesture Recognition, which is efficient, direct and nature, has become one of the key techniques of human-compute interaction. Meanwhile, the high degree of freedom of hand results in the complexity of gesture, diversity of variation and rapidity of movement, which makes gesture recognition full of challenges. The author mainly focuses on the Histogram of(More)
I adopt the point of view that an ideal language contains features well-matched to the abstract concepts which the problem-solving programmer uses in his own thinking. I also assume that the modifiability of programs is of paramount importance. The features below are not necessarily listed in order of importance; an ideal general-purpose programming(More)
