    Abstract: A method and apparatus for reconstructing digital video is provided. In one embodiment, a method for transmitting an original video stream including at least one frame includes segmenting the frame into a plurality of regions, encoding each region in accordance with one of a plurality of available interpolation algorithms that provides minimal distortion the region, and providing a signal containing information that enables a decoder to identify the interpolation algorithms corresponding to each of the regions. This information enables a decoder to enhance a base layer video stream while minimizing the amount of information that must be provided to the decoder in order to perform the enhancement.

    Abstract: A method for transforming Video-To-Text is disclosed that automatically generates text descriptions of the content of a video. The present invention first segments an input video sequence according to predefined semantic classes using a Mixture-of-Experts blob segmentation algorithm. The resulting segmentation is coerced into a semantic concept graph and based on domain knowledge and a semantic concept hierarchy. Then, the initial semantic concept graph is summarized and pruned. Finally, according to the summarized semantic concept graph and its changes over time, text and/or speech descriptions are automatically generated using one of the three description schemes: key-frame, key-object and key-change descriptions.

    Abstract: A method and system for creating a histogram of oriented occurrences (HO2) is disclosed. A plurality of entities in at least one image are detected and tracked. One of the plurality of entities is designated as a reference entity. A local 2-dimensional ground plane coordinate system centered on and oriented with respect to the reference entity is defined. The 2-dimensional ground plane is partitioned into a plurality of non-overlapping bins, the bins forming a histogram, a bin tracking a number of occurrences of an entity class. An occurrence of at least one other entity of the plurality of entities located in the at least one image may be associated with one of the plurality of non-overlapping bins. A number of occurrences of entities of at least one entity class in at least one bin may be into a vector to define an HO2 feature.
