US10424066B2 Image analyzing apparatus that corrects isolated pixels in target image data
Plural pieces of reference data are stored for plural pixel arrangement patterns. Each piece of reference data indicates which of first-type edge pixels needs to be subjected to determination to determine whether an outside neighboring first-type pixel adjacent to the first-type edge pixel exists. A piece of reference data corresponding to a target pixel block is specified as target reference data. A reference-data-based judgment is executed on the target pixel block to perform the determination onto those first-type edge pixels that are indicated by the target reference data as need to be subjected to the determination. A correction is executed on the target pixel block to correct the type of at least one first-type pixel contained in the target pixel block into the second type in a case where a result of the reference-data-based judgment indicates that no outside neighboring first-type pixel exists with respect to the target pixel block.
US10424065B2 Systems and methods for performing three-dimensional semantic parsing of indoor spaces
Systems and methods for performing three-dimensional semantic parsing of indoor spaces in accordance with embodiments of the invention are disclosed. In one embodiment, a method includes receiving input data representing a three-dimensional space, determining disjointed spaces within the received data by generating a density histogram on each of a plurality of axes, determining space dividers based on the generated density histogram, and dividing the point cloud data into segments based on the determined space dividers, and determining elements in the disjointed spaces by aligning the disjointed spaces within the point cloud data along similar axes to create aligned versions of the disjointed spaces normalizing the aligned version of the disjointed spaces into the aligned version of the disjointed spaces, determining features in the disjointed spaces, generating at least one detection score, and filtering the at least one detection score to determine a final set of determined elements.
US10424061B2 Method for assigning tissue normalization factors for digital image analysis
Staining of tissue is a common approach utilized to visualize a gene product in tissue context. In certain applications, it is necessary to report a sum of events within the tissue as a specific function of the target tissue area, which is a sub-area of the total tissue, as a normalization factor for reporting the quantification. Here, we describe methods of determining target tissue area and reporting a quantification which is ratiometric to the target tissue area, utilizing computer algorithms. It is important to assign a value for the “target tissue area” in scenarios where a tissue area normalization factor is needed in the most pathologically relevant fashion during the application of tissue image analysis. We have created methods for determining and reporting “target tissue area” as normalization factor which are useful in diagnostic applications utilizing image analysis.
US10424050B2 Image processing apparatus and image processing method
[Object]To avoid an image quality deterioration due to image processing while maintaining a resolution of an image in a variable-rate-controlled stream.[Solving Means]An image processing apparatus includes a resolution acquisition section, an image enlargement and reduction section, and an image conversion section. The resolution acquisition section acquires a resolution of each of a plurality of temporally-consecutive images. An enlargement and reduction percentage generation section generates an enlargement and reduction percentage for each of the plurality of images based on the acquired resolution. The image enlargement and reduction section performs image enlargement and reduction processing on each of the plurality of images according to the generated enlargement and reduction percentage. The image conversion section performs image conversion processing on each of the plurality of images subjected to the image enlargement and reduction processing.
US10424042B2 Replicating graphics processor operation on a data processing system
A data processing system replicates the operation of a target graphics processor using a graphics processor of the data processing system. A driver for the target graphics processor converts higher level commands and program expressions intended for the target graphics processor into lower level control data and instructions suitable for use by the target graphics processor. The lower level control data and instructions suitable for use by the target graphics processor are then converted into lower level control data and instructions for the graphics processor of the data processing system. The graphics processor of the data processing system then generates an output using the lower level control data and instructions for the graphics processor of the data processing system. The data processing system provides an efficient and comprehensive testing environment when replicating the operation of the target graphics processor.

US10424032B2 Methods for administering preventative healthcare to a patient population
Methods for administering preventative healthcare measures to a patient population are disclosed. A patient population eligible to receive certain healthcare benefits is defined and thereafter multiple sources of healthcare data are compiled and analyzed to create health profiles for each individual. An objective set of criteria for providing preventative care is provided to eligible members within the patient population and appropriate healthcare is administered to the degree necessary to make sure a sufficient percentage of the population receives adequate healthcare treatment consistent with the recognized, objective healthcare standards. Patients remaining non-compliant are sought for further administration of healthcare until requisite compliance standards are met.
