A display arrangement comprises an image display device having a first camera directed towards positions adopted by users viewing the display; one or more further cameras directed towards other respective locations; a face detector for detecting human faces in images captured by the
7636456 Selectively displaying information based on face detection December 22, 2009
A display arrangement comprises an image display device having two or more sets of images for display; a camera directed towards positions adopted by users viewing the display; a face detector for detecting human faces in images captured by the camera, the face detector being arranged to
7636453 Object detection December 22, 2009
A video data processing apparatus, that processes video data including a sequence of images, the apparatus including: an object tracker unit configured to detect a presence of one or more objects within an image and to track a detected object across successive images; an identity ass
7630561 Image processing December 8, 2009
An image processing method for selecting a subset of n (where n is two or more) images representative of a test set of images. The method includes detecting a degree of similarity between images in the test set of images so that the subset of images comprises those n images having su
7522772 Object detection April 21, 2009
Image object detection apparatus in which test regions of a test image are compared with an image property model, a mask defining a subset of pixel positions within a test region, comprises means for comparing pixel properties in the test image defined by the test regions with the image
7515739 Face detection April 7, 2009
A face detection apparatus associated methodology is provided to generate an output indicating a likelihood of a region of an image containing a face. The apparatus includes a comparing device for comparing the region with face data that indicates a presence of the face and for detecting
7490123 Data compression February 10, 2009
A data compression apparatus for performing data compression on input data comprises a quantisation parameter estimation arrangement for deriving an estimated value of a quantisation parameter used in a previous compression/decompression cycle applied to the input data, by detecting
7430314 Face detection September 30, 2008
Face detection apparatus generating an output indicative of the likelihood of test regions of a test image containing a face comprises: means for deriving a plurality of sets of image attribute data from the test region, each set relating to the test region scaled by a respective dif
7421149 Object detection September 2, 2008
A system and associated methodology of detecting objects using multiple sets of object probability data relating to different respective expected object sizes relative to the image size. A list of locations in an image where an object has been detected is stored, the list defining a
7336830 Face detection February 26, 2008
Video face detection apparatus in which a test image from a video sequence is compared with an image property model derived from image properties of a region detected to contain a face in a preceding image in the video sequence comprises: selecting a predetermined proportion of pixels in
7227900 Differential encoding June 5, 2007
An encoding apparatus operable to encode video data representing successive images, each image including a plurality of pixels. The apparatus includes a differential encoder arranged to encode each image as one or more predetermined image regions. Each image is being encoded as a ref
6993080 Signal processing January 31, 2006
A decoder 2 decodes a first compressed digital video bitstream whilst preserving the compression parameters thereof, the compression parameters including a first buffer occupancy value VBV.sub.--1 representing the occupancy by the said first bitstream of a buffer of the decoder. A si
