20100067801 | Network Surveillance System - A method for estimating the activity topology of a set of sensed data windows is described. Each of the sensed data windows related to a corresponding sensed region. The method includes the steps of determining a subset of sensed data windows that are not connected; and excluding the subset of sensed data windows from the set of sensed data windows. In one embodiment, the sensed data windows corresponding to image windows such as would be provided by a visual surveillance system. | 03-18-2010 |

20140204239 | COLOUR CALIBRATION METHOD FOR AN IMAGE CAPTURE DEVICE - A method for providing a mapping from apparent colour to actual colour for an image capture device including capturing an image of a reference colour chart having a plurality of colour patches using the image capture device, wherein each colour patch has an associated reference colour, measuring the apparent colour of the plurality of colour patches in the captured image, selecting a plurality of control points representing different hue values within a circular hue space, determining an angular offset for each control point such that the distance between a transformed apparent colour and the reference colour for each colour patch is minimised, the angular offset representing a hue correction, wherein interpolation of the angular offsets for the control points provides a mapping from apparent colour to actual colour for the image capture device. | 07-24-2014 |
20140219538 | METHOD AND SOFTWARE FOR ANALYSING MICROBIAL GROWTH - A method for analysing microbial growth on a solid culture medium, the method including obtaining image data of the solid culture medium and any microbial growth, generating an associated feature vector of values obtained by applying one or more filters to the image data, using a classifier to classify each pixel in a plurality of pixels in the image data based on the associated feature vector, analysing results of pixel classifications of each said pixel to derive a microbiological assessment of the solid culture medium and any microbial growth, and outputting the microbiological assessment. | 08-07-2014 |
20140219553 | METHOD FOR IMPROVING CLASSIFICATION RESULTS OF A CLASSIFIER - A method for improving classification results of a classifier including receiving classification results for a plurality of elements that have been classified by a classifier as one of a plurality of classes, constructing a graph having a plurality of nodes, each node corresponding to one of the elements, and a plurality of labels, each label corresponding to one of the classes, adding edges between nodes corresponding to related elements, adding edges between each node and each label, and using a graph cut algorithm to cut edges to a node and partition the graph into classes, the graph cut algorithm using as input the classification results for the element corresponding to that node and related elements. | 08-07-2014 |
