Title: Estimating vehicle speed from video stream motion vectors
Inventor: BERNAL EDGAR
IPC: G08G1/04
Filed: 2013-08-28
Abstract: Video motion vector clusters corresponding to a moving vehicle are identified and tracked across multiple frames of captured video. Movement of the motion vector clusters is translated from pixels per second to real speed (e.g. kilometres or miles per hour) to determine whether the vehicle is speeding. Estimated speed data is added to the video stream data as metadata, and video segments of candidate speeding vehicles are stored or transmitted for subsequent automated or manual review. Automated low-complexity video-based vehicle speed estimation is thereby provided. The system may form part of a multi-layer speed enforcement system, in which deeper layers provide enhanced accuracy on selected candidate (speeding) vehicles.

Title: Echo path change detector
Inventor: MANI SENTHIL KUMAR
IPC: H04M9/08
Filed: 2013-12-23
Abstract: An echo path monitoring system for controlling an adaptive filter configured to estimate an echo of a far-end signal comprised in a microphone signal, the system comprising a comparison generator configured to compare the microphone signal with the estimated echo to obtain a first comparison and compare an error signal, which represents a difference between the microphone signal and the estimated echo, with the estimated echo to obtain a second comparison, and a controller configured to combine the first and second comparisons to form a parameter indicative of a state of the microphone signal and, in dependence on said parameter, control an operating mode of the adaptive filter. Thus, the echo path change detector may control the adaptive filter to operate in a mode that is appropriate to the state of the microphone signal. Suitably this involves controlling the filters adaptation. Detecting echo path change quickly and accurately allows the filter to be placed in an operational mode that is better able to adapt quickly to the new echo path than its conventional mode of continuous adaptation.
