Title: Method and apparatus for tracking an object
Inventor: MATSON GARY PAUL
IPC: G06T7/00
Filed: 2014-07-30
Abstract: In a method of tracking an object, a plurality of images of a target object is obtained and a super-resolved image of the target object is calculated from the plurality of images which may include averaging all regions of interest in the plurality of images that are the same phase and/or extracting frame portions from the image and storing said portions in a stack. A further image of the target object is then obtained which is correlated with the super-resolved image, in order to identify the location of the target object in the further image. The correlation may be in the spatial or frequency domain and prior to any correlation the super resolution image may be de-resolved.

Title: Comfort noise generation
Inventor: SENTHIL KUMAR MANI
IPC: H04M9/08
Filed: 2014-11-06
Abstract: Ambient background comfort noise is generated for a stream of audio (eg. speech) frames 203 by characterising the frequency content of a frame to produce analysis filter parameters (eg. via Linear Predictive Coding 207) which generate residual samples which are stored if the frame does not comprise speech according to voice activation analysis 205. These residual samples are then selected from randomly 211 in order to generate comfort noise from a synthesis filter 212, which may replace speech echoes without suggesting that the call is ended via complete silence.
