The disclosure herein relates to systems, methods, and devices for medical image analysis, diagnosis, risk stratification, decision making and/or disease tracking. In some embodiments, the systems, devices, and methods described herein are configured to analyze non-invasive medical images of a subject to automatically and/or dynamically identify one or more features, such as plaque and vessels, and/or derive one or more quantified plaque parameters, such as radiodensity, radiodensity composition, volume, radiodensity heterogeneity, geometry, location, and/or the like. In some embodiments, the systems, devices, and methods described herein are further configured to generate one or more assessments of plaque-based diseases from raw medical images using one or more of the identified features and/or quantified parameters.

A computing system may generate an initial segmentation mask by applying a neural network to a 3D image of a set of objects. The initial segmentation mask associates voxels of the 3D image with individual objects of the set of objects. Additionally, the computing system generates a refined segmentation mask. As part of generating the refined segmentation mask, the computing system performs, for each respective object, a front propagation process for the respective object. The front propagation process for the respective object uses input voxel data to relabel, in the refined segmentation mask, voxels of the 3D image as being associated with the respective object. A stopping condition of a path evaluated by the front propagation process for the respective object occurs when the front propagation process evaluates a voxel identified in the initial segmentation mask as being associated with a different one of the objects from the respective object.

To realize a configuration enabling processing of displaying a flight path of a drone on a live-action image of the drone and the like. A data processing unit of a user terminal sets a real object included in a camera-captured image as a marker, generates marker reference coordinates with a configuration point of the set marker as an origin, and transmits position data on the marker reference coordinates to a mobile device such as a drone with the marker reference coordinates as coordinates shared with another device, for example, a mobile device such as a drone. For example, the data processing unit transforms the destination position of the drone or the position of the tracking target from the coordinate position on the user terminal camera coordinates to the coordinate position on the marker reference coordinates by applying the coordinate transformation matrix, and transmits the transformed coordinate position to the drone. In addition, the data processing unit receives the movement path from the drone as coordinate position data on the marker reference coordinates, transforms the coordinate position data into a coordinate position on the user terminal camera coordinates by applying the coordinate transformation matrix, and displays the path information on the display unit.

The present invention provides a device for taking pictures. The device includes: a camera; a display; and a processor configured to capture a plurality of temporary images of one or more subjects by using the camera; extract a reconstructed scene from the plurality of temporary images; capture a focused image that a user intends to take a picture by using the camera; generate a subject map in the focused image by using the reconstructed scene; estimate an armature from the subjects selected from the subject map; combine the armature with the focused image; verify whether the composition of the focused image is good or not; and present an instruction to the user to adjust the composition by using the display. The present invention achieves an improved photography composition.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing a series of images of a patient's anatomy to determine a cut plane for use during a knee procedure. To determine a cut plane for use during a knee replacement procedure, the 2D images may be analyzed by a computer program to determine a best fit plane through one or more points along the proximal surface of the tibia and to determine one or more features of depressions within the proximal surface. With these landmarks identified in the images, a cut plane through the tibia for use during a TKA procedure may be determined. Further, the location of these features in the images may be determined by analyzing the gray scale value of one or more pixels around a selected point on the image. The pixel with the lowest gray scale value may then be assumed to be the edge of the cortical bone in the 2D image.

The invention is a method of geo-positioning geographic data for visualisation of a geographic area, particularly a mine site, and a device to work the method. The method includes the steps of: importing two or more data sources having geographic data of the geographic area; selecting a first control in a first data source of the two or more data sources and the same first control in a second data source of the two or more data sources; selecting a second control in the first data source and the same second control in the second data source; and applying an algorithm in a processor to process the first control in the first data source, the first control in the second data source, the second control in the first data source and the second control in the second data source by overlaying, rotating and scaling the data sources until at least the first control in the first data source matches the first control in the second data source and the second control in the first data source matches the second control in the second data source.
