摘要： The present disclosure relates to a system and method capable of utilizing augmented reality and/or mixed reality to guide a user through the performance of a high-quality health-related examination. A head-mounted augmented reality device, smartphone, tablet or alternate display device allows the user to simultaneously view virtual exam guidance elements alongside real-world objects such as relevant anatomical landmarks or the exam detector. The virtual exam guidance elements are generated and/or updated in real-time based on pre-determined exam protocols as well as relevant data streams, such as data from cameras, sensors, the exam detector or other sources. The guidance elements are generated and/or positioned in 3D space in order to demonstrate to the user the preferred techniques or maneuvers that should be performed. In an exemplary embodiment, the system and method are designed for the performance of high-quality cardiac, venous, arterial, obstetric, genitourinary, abdominal or musculoskeletal ultrasound exams.

摘要： Present aspects are directed to a system that receives digital images of parcels at various points throughout a transportation and logistics network. Based on analysis of a single digital image of a parcel, the dimensions of the parcel are detected and calculated. A single digital image of a parcel is captured at various points throughout a transit or shipping network. The single digital image is processed using computer vision for image manipulation. Key identifying points of the parcel (e.g., a label or bar code) can be detected through the processing. The processed digital image is input into a mathematical model that generates an estimate for all dimensions of the parcel.

摘要： Methods are provided for locating 3D rectangular objects on surfaces, each object having substantially the same X, Y and Z dimensions as the other objects on the surface. An image of a surface having objects arranged thereon is obtained. The image includes pixels arranged in rows and columns. As each object has the same Z-dimension, the surface shown in the image is planar. From the image, the X and Y dimensions, and X, Y coordinates of a center for each object are determined. Edge points are detected utilizing gradient evaluation. The X and Y dimensions of the objects are determined by counting the frequency of distances between edge points and X, Y coordinates of the center location for each object is determined by identifying positions in the image that have a concentration of edge points at a distance equivalent to one-half the size (X or Y dimension) of the objects.

摘要： Various techniques are provided to process captured thermal images to determine whether the thermal images exhibit degradation associated with environmental effects and/or security conditions. In one example, a method includes capturing a plurality of thermal images of a scene. The thermal images are processed to generate first and second background images associated with first and second time periods to filter out changes in the scene occurring within the associated time periods. The first and second background images are edge filtered to generate first and second edge images. The first and second edge images are compared to determine a change in edges associated with the scene. A device is selectively operated in a fail-safe mode in response to the comparing. Additional methods and related systems are also provided.

摘要： A method for detecting a known pattern having homogeneous areas includes the steps of taking an image of the known pattern or, of at least a portion of the known pattern, and performing detection. Detection includes an initial detection of a first region of the image and the detection of a feature of the known pattern within a second region of the image. The second region is arranged adjacent to the first region. The initial detection is aimed at estimating at least one region parameter, such as a position of the region of the pattern, and/or orientation of the region or distortion of same. Starting from this, the second region can be selected in which a feature, such as a corner of the checkerboard is detectable. This second detection step is aimed at obtaining at least one region parameter such as the position of a feature within the second region.

摘要： A contour detection apparatus includes a processor. The processor learns to detect a nail contour being a detection target by setting an initial shape including feature points based on learning data each being image data on a finger including a learning target nail, and setting, as a reference point, a feature point among the feature points corresponding to a reference position, thereby obtaining contour detection information. The processor arranges, in treatment target data being image data on a finger including a treatment target nail, an initial position of the shape such that a point corresponding to the reference position in a contour of the finger including the treatment target nail is superposed on the reference point, and fits the shape to the treatment target nail from the initial position, thereby detecting the nail contour of the treatment target nail.
