Abstract
The present invention provides a method for identifying the size, shape, and location of objects in a specimen wherein the image of the specimen is represented by image data and wherein the image data is processed to provide mask data representing a mask wherein the mask identifies the size, shape, and location of the object. Generally, the method includes the step of enhancing the image and creating a threshold image wherein the threshold image includes a threshold intensity value associated with each pixel of the image. The threshold image is combined with the original image to provide a mask image that identifies the size, shape, and location of the objects. The mask image may be further refined to ensure accurate identification of the object. Various other techniques are disclosed within the general method for processing image data.
