  • Chromatin segmentation
    Patent number: 7574304
    Abstract: A method of segmenting chromatin particles in a nucleus of a cell by locating regional minima in an image, computing a zone of influence (ZOI) around each regional minimum, and segmenting a single chromatin blob within each ZOI using a region growing procedure. The method can be used as the basis of a method of qualitatively characterizing the distribution of nuclear chromatin by computing features for individual chromatin particles. Chromatin features can be synthesized from the features of individual particles and particle features can be synthesized into nucleus features and slide features. The method is useful for detecting malignancy associated changes and changes during neoplasia. The method may also be used more generally to assess chromatin patterns in living cells during the cell life cycle. This makes it possible to measure alternations in the evolving patterns that result from pathological or environmental influences.

  • Unsupervised scene segmentation
    Patent number: 7142732
    Abstract: A method of segmenting objects in an image is described. The method applies a Top Hat algorithm to the image then constructs inner and outer markers for application to the original image in a Watershed algorithm. The inner marker is constructed using binary erosion. The outer marker is constructed using binary dilation and perimeterisation. The method finds particular application for first level segmentation of a cell nucleus prior to detailed analysis.

  • Method for image texture analysis
    Patent number: 6882748
    Abstract: A method and apparatus for image texture analysis in which the image is mapped into a first set of binary representation by a monotonically varying operator, such as a threshold operator. Each binary representation in the first set of binary representations is mapped to a further set of binary representations using a second monotonically varying operator, such as a spatial operator. The result of the two mappings is a matrix of binary image representations. Each binary image representation is allocated a scalar value to form an array of scalar values which may be analysed to identify defined texture characteristics.
