Abstract: A system and process for video characterization that facilitates video classification and retrieval, as well as motion detection, applications. This involves characterizing a video sequence with a gray scale image having pixel levels that reflect the intensity of motion associated with a corresponding region in the sequence of video frames. The intensity of motion is defined using any of three characterizing processes. Namely, a perceived motion energy spectrum (PMES) characterizing process that represents object-based motion intensity over the sequence of frames, a spatio-temporal entropy (STE) characterizing process that represents the intensity of motion based on color variation at each pixel location, a motion vector angle entropy (MVAE) characterizing process which represents the intensity of motion based on the variation of motion vector angles.

Abstract: An application server based in a communication network facilitates help desk support for end users that employ a camera-equipped wearable device. Upon receiving a request from a user for assistance with a problem or task, the application server controls the wearable device to collect multimedia information—e.g., images, video, and sounds—associated with an object of the task. The application server then crowdsources the collected multimedia information to a plurality of other remote user devices. Based on helpful information received from users of the remote devices, and/or an analysis performed at the server, the application server categorizes the task. So categorized, the application server can retrieve pertinent assistance data associated with the task and send that information to the user.

Abstract: A model-based compression codec applies higher-level modeling to produce better predictions than can be found through conventional block-based motion estimation and compensation. Computer-vision-based feature and object detection algorithms identify regions of interest throughout the video datacube. The detected features and objects are modeled with a compact set of parameters, and similar feature/object instances are associated across frames. Associated features/objects are formed into tracks and related to specific blocks of video data to be encoded. The tracking information is used to produce model-based predictions for those blocks of data, enabling more efficient navigation of the prediction search space than is typically achievable through conventional motion estimation methods. A hybrid framework enables modeling of data at multiple fidelities and selects the appropriate level of modeling for each portion of video data.

Abstract: A moving object location/attitude angle estimation device acquires a fish-eye lens image capturing a surrounding environment of a moving object with a fish-eye lens, and acquires a less distorted pinhole image for a predetermined region of the fish-eye lens image. Then, a bend degree of a driving road in a travelling direction of the moving object is detected. When the detected bend degree is less than a predetermined value, the pinhole image is selected. On the other hand, when the bend degree is not less than the predetermined value, the fish-eye lens image is selected. Thereafter, a location and an attitude angle of the moving object are estimated by matching edge information of the selected image with a three-dimensional map data.
