Coverslip detection locating all four coverslip edges. A field of view processor receives image data from a charge coupled device camera. The charge coupled device camera images a slide and coverslip that is mounted on a movable frame. The slide and coverslip are illuminated from below with a uniform light source. The moveable frame is under computer control and moves in response to the field of view processor. The field of view processor locates the coverslip by first positioning the movable frame to view a portion of the slide on a predetermined potion of the slide within a predetermined area of the slide. The slide is then re-imaged after the movable frame moves the slide toward a chosen edge of direction. Edge type objects are located and followed over multiple fields of view. If the edge object satisfies a set of predetermined criteria the coverslip edge has been found. The edge is extended to find all four corners of the coverslip. The edge objects are processed using morphological operators.

A Recognition Frame presents multi-level application elements to the user simultaneously through a computer graphical user interface. The interface consists of an image display panel for displaying image channels; a data display panel for displaying object measurements and summary statistics; a configuration display panel for displaying recipe content; a master tab for selecting the panels. It also consists of a processing toolbar for context dependent processing tool display. The Recognition Frame further comprises a second side frame for data object display and charting. The second side frame has a tabular arrangement consisting of properties tab, controls tab, and charts tab. The Recognition Frame links application elements through a complex data model wherein interface display is automatically updated when one element is changed.

摘要:
A decision regulation method separates noise from consistent application domain characteristics and integrates multiple types of information to create robust decisions that work well for the application in spite of the application dynamics and/or errors in training data. Adjustment is made between a local and global decision basis to yield a balance point to match the application. Unequal class prevalence of the training data is compensated. The decision tree generation process is also regulated using information integration. Reliability measures and new pruning methods are taught for optimization of hierarchical decision structures.

A reduced instruction set architecture implements complicated image processing algorithms that are decomposed into combinations of simple operations. The simple operations are further decomposed into multiple operations of one dimensional data with an address controller to scan data in a highly flexible fashion for multi-dimensional applications.

A method for high speed morphological processing in a computerized image processing system starts by acquiring a binary image and selecting feature and height values corresponding to a desired morphological processing of an image. The image is scanned in a raster scanning sequence so as to produce a scanned image including a plurality of pixels. A sequential labeling transformation is performed on each of the plurality of pixels of the scanned image so as to produce a transformed image. A thresholding operation is performed on the transformed image. The resultant image is translated.

A classifier measures robustness responsive to object presentation effects and decision boundary effects. A cytological image analysis computer obtains objects of interest and classifies them responsive to a decision tree classifier. The robustness of classification is calculated dynamically as objects are classified responsive to a segmentation robustness and a classification decisiveness measure. The results of the decisiveness measure and the segmentation robustness data are combined to provide enhanced overall classification reliability.
摘要:
A method for identifying the size, shape, and location of objects in a specimen where the image of the specimen is represented by image data and where the image data is processed to provide mask data representing a mask where 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 where 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.
摘要:
The detection of optical stripes on an image of a glass slide of material of interest. An automated microscope system with an illuminator having a spatial intensity homogenizer provides spatially uniform illumination of a microscope slide specimen. Periodic optical patterns formed from the illumination system are detected by a computer system. The computer forms a high transmission mask of an image of the biological specimen. Edges in the image are detected and a low transmission area process is performed. Horizontal stripes are enhanced. A final thresholding generates a binary image of the patterns. Stripes in the patterns are detected an a stripe flag and strip area are calculated.
