| 20090026638 | METHOD OF FORMING A COATED OPTICAL ELEMENT - A method of forming a coated optical element is disclosed herein. The method uses a mould having first and second mould sections that will form front and back surfaces of the optical element, one of the mould sections having a casting face. The method includes the steps of: applying an abrasion resistant coating layer to the casting face of a mould section, the casting face being capable of imparting a desired optical configuration on a surface of the optical element; treating the abrasion resistant coating layer to prevent damage to the layer during subsequent steps; applying a second coating layer to the abrasion resistant coating layer to substantially cover the abrasion resistant coating layer; treating the second coating layer to provide at least weak adhesion of the second coating layer to the abrasion resistant coating layer and to prevent damage to the second layer during subsequent steps; filling the mould with an organic liquid material; and hardening the organic liquid material so as to form the optical element adhered to the second coating layer. | 01-29-2009 |

| 20120062699 | DETECTING STEREOSCOPIC IMAGES - To detect the presence of the two constituent images of a stereoscopic image within an image frame, a row of vertically-averaged pixels is derived from the upper half of the frame and compared with a second row of vertically-averaged pixels derived from the lower half of the frame. Similarly, a column of horizontally-averaged pixels is derived from the left half of the frame and compared with a column of horizontally-averaged pixels derived from the right half of the frame. | 03-15-2012 |

| 20090034876 | IMAGE ANALYSIS - The present invention relates to a method of and apparatus for image analysis and in particular may relate to the detection of cross-fades in film or video sequences. The invention relates in particular to a method of analysing an image of a sequence of images to determine a cross-fade measure based on determined temporal picture information transitions associated with picture elements of the image. In particular, the cross-fade measure may be determined based on the extent to which the temporal picture information transitions are uniform. The method and apparatus of the invention can provide a measure of likelihood of a cross-fade in a single pass. In addition the described method can be accomplished in real-time or close to real-time. In addition the cross-fade detection results are comparable with, or better than, the results achieved by the prior art methods. | 02-05-2009 |
| 20090103812 | IMAGE ANALYSIS - This invention concerns image analysis of video signals or data in order to detect prior, block-based processing, and to quantify block-related picture impairments. Adjacent samples of video data are high pass-filtered, rectified and auto-correlated to form an auto-correlation function. The auto-correlation function may be analysed to provide information regarding block size and other block artefact measures. | 04-23-2009 |
| 20100045693 | PICTURE ATTRIBUTE ALLOCATION - The invention concerns image processing and, in particular, the processing of picture attribute fields for an image. A method of obtaining a new picture attribute field of an image is disclosed in which a picture attribute value at one position is allocated to a new position in the image in dependence upon the value of a parameter, such as luminance data, at the original position and at the new position and/or in dependence on the distance between the original position and the new position. The invention may be used to process picture attribute fields comprising: motion vectors; motion vector confidence; segment labels; depth labels; texture labels. | 02-25-2010 |
| 20100225823 | REGIONAL FILM CADENCE DETECTION - The temporal sampling pattern of a sequence of images that represents a moving scene is classified into classes of temporal sampling patterns including “film”, “video” and “still”. Pixels in each image in the said sequence are classified according to the relationship between signed inter-image pixel-value differences f | 09-09-2010 |
| 20100303357 | DETERMINING A REGIONAL SHOT-CHANGE PARAMETER - To determine a regional shot-change parameter for an image identified as a whole as a shot change image, a difference is taken between each pixel in that image and a spatially equivalent pixel in an adjacent image in the sequence. A pixel is flagged as a shot-change pixel when the difference for that pixel and around three of the spatially adjacent pixels exceed a threshold. If a pixel is spatially isolated from other shot-change pixels, it is not regarded as a shot-change pixel. | 12-02-2010 |
