Patent number: 9256941Abstract: An analysis of a digitized image is provided. The digitized image is repeatedly convolved to form first convolved images, which first convolved images are convolved a second time to form second convolved images. Each first convolved image and the respective second convolved image representing a stage, and each stage represents a different scale or size of anomaly. As an example, the first convolution may utilize a Gaussian convolver, and the second convolution may utilize a Laplacian convolver, but other convolvers may be used. The second convolved image from a current stage and the first convolved image from a previous stage are used with a neighborhood median determined from the second convolved image from the current stage by a peak detector to detect peaks, or possible anomalies for that particular scale.Type: GrantFiled: October 6, 2014Date of Patent: February 9, 2016Assignee: VUCOMP, INC.Inventors: Jeffrey C.

Patent number: 9076197Abstract: A PDF estimator for determining a probability that a detected object is a specific type of object is provided. Training data from a known set is used to functionally describe the relevant neighborhood for specific representation points. The neighborhood is selected based on the measured features of the object to be classified and weights are calculated to be applied to the representation points. A probability is determined based upon the stored training data, the measured features of the object to be classified, and the weights.Type: GrantFiled: April 29, 2011Date of Patent: July 7, 2015Assignee: VuComp, Inc.Inventor: Jeffrey C.

Publication number: 20050152589Abstract: A system and method for electronically displaying CAD results are disclosed. In one exemplary embodiment, a flat panel display is attached to a film multi-viewer via an articulated arm that allows a radiologist to position the flat panel display with respect to the multi-viewer. A barcode scanner is mounted to the back of the display, allowing case identifiers on CAD hardcopy printouts to be read in order to indicate which results are to be viewed. A small embedded computer is mounted with or near the flat panel display and the barcode scanner, and retrieves CAD results from a remote CAD server when a case identifier is read by the barcode scanner. Other embodiments are described and claimed.Type: ApplicationFiled: November 23, 2004Publication date: July 14, 2005Applicant: VuComp, Inc.Inventors: Jeffrey Wehnes, Eric Toncre, Shelley Ahrens, Adam Hina, Brant Lewis
