  • Wave field microscope with sub-wavelength resolution and methods for processing microscopic images to detect objects with sub-wavelength dimensions
    Patent number: 8155409
    Abstract: The invention relates to a computer implemented method for processing of microscopic images to detect objects of interest. The method includes subjecting the microscopic image to a bandpass filtering to obtain a filtered image, wherein the bandpass filtering is such as to suppress the noise and any objects which are larger than a predetermined size; and processing the filtered image at a plurality of progressively decreasing threshold levels. The processing at each threshold level includes detecting the objects of interest using an object labelling algorithm and removing the detected objects detected at a given threshold level from the working image before proceeding to the next threshold level.
