Patent number: 9946953Abstract: A computer implemented image processing method is provided for identifying a tissue boundary of a tumor region of a tissue sample, the tissue sample containing non-tumor regions and at least one tumor region. The method includes obtaining an image of a tissue section of the tissue sample, identifying at least one image property of the image, and comparing the image property with classification data. The method further includes, based on the comparison, classifying a region of the image as a tumor region representing a tumor region in the tissue sample or a non-tumor region representing a non-tumor region in the tissue sample. If the region of the image is classified as a tumor region, the method includes identifying a boundary of the region of the image, and using the boundary to identify a tissue boundary of the tumor region of the tissue sample represented by the region of the image.Type: GrantFiled: November 10, 2015Date of Patent: April 17, 2018Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jonathon Tunstall, Peter Hamilton, Yinhai Wang, David McCleary, James Diamond

Patent number: 9374661Abstract: A facility comprising methods and systems for discovering travel patterns based at least in part on data collected from a plurality of dynamic and/or mobile sensor devices is disclosed. The mobile sensor devices sense or detect the presence of nearby devices and record information about each detection, such as the location, the date and time, and an identifier of the detected device and provide this information to the facility. Thus, the facility can leverage the communication capabilities of existing mobile devices and networks to provide a broad, wide-ranging, scalable sensor network that detects the presence of individual devices. By recording and analyzing the encounter data received from various mobile sensor devices, the facility can ascertain or estimate the path of devices and their associated users. Given the availability of mobile devices and mobile networks, the disclosed techniques can be deployed without a substantial investment in infrastructure and maintenance.Type: GrantFiled: April 2, 2013Date of Patent: June 21, 2016Assignee: University of Washington through its Center for CommercializationInventors: Yegor Malinovskiy, Yinhai Wang

Patent number: 8358808Abstract: Systems and methods for detecting and tracking objects, such as motor vehicles, within video data. The systems and method analyze video data, for example, to count objects, determine object speeds, and track the path of objects without relying on the detection and identification of background data within the captured video data. The detection system uses one or more scan lines to generate a spatio-temporal map. A spatio-temporal map is a time progression of a slice of video data representing a history of pixel data corresponding to a scan line. The detection system detects objects in the video data based on intersections of lines within the spatio-temporal map. Once the detection system has detected an object, the detection system may record the detection for counting purposes, display an indication of the object in association with the video data, determine the speed of the object, etc.Type: GrantFiled: January 10, 2011Date of Patent: January 22, 2013Assignee: University of WashingtonInventors: Yegor Malinovskiy, Yinhai Wang, Yao-Jan Wu

Patent number: 7786855Abstract: Traffic induction loop simulator (LOOPSIM) software, and a system and method designed for traffic research and education. The system is able to generate output signals in response to previously recorded real traffic events or simulated traffic. If directly connected to a controller cabinet or a traffic event data collection system, LOOPSIM can be used to simulate output signals from loop detectors and to test algorithms executable in the controller, or to test the performance of a traffic data collection/monitoring system. LOOPSIM can simulate different predefined patterns of traffic distributions and replay loop event data recorded by a detector event data collection (DEDAC) system or an advanced loop event data analyzer (ALEDA) at a pace responsive to controller feedback. Using LOOPSIM, many traffic system tests can be conducted for multi-purpose traffic control applications, and traffic arrival patterns can be generated for researchers and educators to test theoretical models.Type: GrantFiled: August 7, 2006Date of Patent: August 31, 2010Assignee: University of Washington through its Center for CommercializationInventors: Patikhom O.
