<p>An aspect of the invention provides a method of detecting discrete features in an original image. The method includes various steps. Pixels in an original image array having an intensity with a predetermined relationship to a selected intensity threshold level are identified. The identified pixels are positioned in corresponding positions in an intermediate data array to form an intensity plane. The intermediate data array is analyzed using at least one test to determine whether any area in the intensity plane is consistent with a characteristic of the feature to be detected. Where an area in the intensity plane is accepted as being consistent with the characteristic of the feature to be detected, the pixels for that area are copied from the original image to a storage image array and a position indication of the accepted area is recorded. These steps are then repeated at least once using a lower or higher selected intensity threshold level. A stepwise segmentation approach thus involves simplification of an original image and a series of basic characteristic (for example shape) tests. An example of the application of the invention is for image analysis in proteomics.</p> |
