09/296833

International Classification:

G06T 1120

US Classification:

Abstract:

A method for encoding a non-manifold polygonal mesh operates by converting an original (non-manifold) model to a manifold model, encoding the manifold model using a mesh compression technique, and clustering, or stitching together during a decompression process, vertices that were duplicated earlier to faithfully recover the original connectivity. By separating the connectivity from model geometry and properties, the method avoids encoding vertices (and properties bound to vertices) multiple times. This provides a reduction in the size of the bit-stream compared with encoding the model as a manifold.

US Classification:

Abstract:

A hardware assisted system and method for computing a visibility ordering of a set of primitives and rendering the set of primitives is described, comprising the steps of and means for locating primitives potentially in a layer and removing occluded primitives from the layer. The hardware assisted locating step further includes the steps of initializing hardware buffers, initializing a layer number, assigning the layer number to each primitive, extracting a subset of the primitives from the set of primitives assigned to the layer number, and storing the subset of primitives in a color buffer. The hardware assisted removing step further includes the steps of reading the color buffer to locate all primitives of the layer number, traversing a pixel array of the subset of primitives to obtain primitive ids and depth complexities, testing depth complexity for each primitive using a stencil buffer, removing those primitives from the layer number if the depth complexity greater than one, re-inserting the primitives with a depth complexity greater than one back into the set of primitives, rendering the primitives of the layer number, incrementing the layer number, determining if any primitives have been extracted from the set of primitives in the layer number, halting execution if no primitives have been removed from the layer number, and repeating all of the above steps.

Abstract:

A method and apparatus are disclosed for finding a triangle mesh that interpolates a set of points obtained from a scanning system. A ball-pivoting algorithm computes a triangle mesh interpolating a given point cloud. The disclosed ball-pivoting algorithm triangulates a set of points by “rolling” a ball of radius r on the point cloud. The points are surface samples acquired with multiple range scans of an object. The ball-pivoting algorithm starts with a seed triangle, and pivots the ball of a given radius, r, around an edge of the triangle. During the pivoting operation, the ball revolves around the edge while keeping in contact with the edge's endpoints. The ball pivots until it touches another scan point, forming another triangle. The ball-pivoting operation continues until all reachable edges have been tried, and then starts from another seed triangle, until all scan points have been considered.

International Classification:

G06T 3/40

G06K 9/00

Abstract:

A modular tracking system is described comprising of the network of independent tracking units optionally accompanied by a LIDAR scanner and/or (one or more) elevated cameras. Tracking units are combining panoramic and zoomed cameras to imitate the working principle of the human eye. Markerless computer vision algorithms are executed directly on the units and provide feedback to motorized mirror placed in front of the zoomed camera to keep tracked objects/people in its field of view. Microphones are used to detect and localize sound events. Inference from different sensor is fused in real time to reconstruct high-level events and full skeleton representation for each participant.

Abstract:

The sport data tracking systems available today are based on specialized hardware to detect and track targets on the field. While effective, implementing and maintaining these systems pose a number of challenges, including high cost and need for close human monitoring. On the other hand, the sports analytics community has been exploring human computation and crowdsourcing in order to produce tracking data that is trustworthy, cheaper and more accessible. However, state-of-the-art methods require a large number of users to perform the annotation, or put too much burden into a single user. Example methods, systems and user interfaces that facilitate the creation of tracking data sequences of events (e.g., plays of baseball games) by warm-starting a manual annotation process using a vast collection of historical data are described.

International Classification:

G06Q 40/04

Abstract:

An exemplary system, method and computer-accessible medium can be provided, which can include, for example, receiving digital data related to a suspicious trade(s), determining a first entity(s) associated with the suspicious trade(s) based on the digital data, and determining a relationship between the first entity(s) and a second entity based(s) on a proximity between the first entity(s) and the second entity(s). The proximity used to determine the relationship can be a logical proximity. The logical proximity can be determined based on a communication(s) between the first entity(s) and the second entity(s).
