Abstract: Various embodiments provide methods and systems for detecting one or more segments of an image that are related to a particular object in the image (e.g., a logo or trademark) and extracting at least one feature point, each of which is represented by one feature point descriptor, based at least upon a contour curvature of the one or more segments. The at least one feature point descriptor can be converted into one or more codewords to generate a codeword database. A discriminative codebook can then be generated based upon the codeword database and utilized to detect objects and/or features in a query image.

Abstract: A method for detecting objects on a parking area for vehicles with the aid of image processing of images from at least two imaging sensors, detection ranges of the imaging sensors overlapping at least partially. The images of an imaging sensor whose image quality is limited by environmental conditions are weighted less strongly for the detection of objects on the parking area during image processing than images of an imaging sensor whose image quality is not limited by environmental conditions. A processing unit, a program, and an overall system for carrying out the method are also described.

Abstract: The disclosure includes a system and method for classifying conditions of a data stream of object information.

Abstract: An apparatus (MDS) and related method for image processing. The apparatus includes a multi-modal matcher (M). The matcher (M) operates to match a first reference (RF1) image against a stream (LF) of image frames (F1, F2). Once a match is found, the current reference image (RF1) is exchanged for a matching frame from the stream. The matcher (M) then attempts matching against subsequent frames in the stream by now using said matched frame as a new reference image. Once a further frame (Fm) is found that matches said new reference image, said further frame (Fm) is output as a best match.

Abstract: The embodiments relate to classifying and grouping images. Primary images and secondary images are created and stored. A preliminary relationship between the primary and secondary images is established. The primary image is compared with the secondary image to produce a relevance score. The relevance score is converted to a secondary image assignment, which includes selectively assigning the secondary image to a first group based on the relevance score.

Abstract: An image of a test receptacle is received, which includes a color of a reaction between a test substance and at least one reagent in the test receptacle, an alignment code having test receptacle identification information, and at least one color calibration block. An array of pixels of RGB values for each pixel in the image is collected. A captured color of the color calibration block is evaluated. An offset is determined for the captured color in the one color calibration block if the evaluation of at the color calibration block in the image determines that the captured color deviates from a baseline color. The offset is applied to each pixel in the image to correct the captured image. A colorimetric analysis is performed on the reaction between the test substance and the at least one reagent.

Abstract: The invention is a system and method used for detection, analysis, and reporting on player metrics of a sporting event using video images. The main components of the invention are: grabbing a digital video image frame or grabbing an analog video image frame and converting the analog video image frame to a digital video image frame, extracting field of play markings from the video image frame(s) for use as image control points, creating a perspective projection registration model based upon the pairing of image control points with a set of user-defined control points representative of the field of play, extracting player image locations on each team from the video image frames, and applying the perspective projection transformation model to register participant image locations to their respective planimetric coordinate position on the user defined field of play.

Abstract: A system and method for tracking the growth of large-area wildland fires. The technique includes monitoring wind conditions in and around a wildfire using near-surface-sited sensors deployed by a high-altitude long-endurance (HALE) unmanned aerial vehicle (UAV), such as the Global Hawk. The deployed sensors measure a localized wind vector at multiple locations within and surrounding the wildfire, and transmit the wind data back to the UAV for relaying to a command center operated by fire management authorities, where the wind data are used to assist decision-making, including as input into wildfire growth prediction models. The sensors may provide additional data such as local altitude/elevation, pressure, temperature and relative humidity. The UAV may also carry sensors that provide additional data to be used by the fire management authorities or the wildfire growth prediction models—such as infrared images defining actively flaming areas, and visual images which indicate vegetation type and density.

Abstract: A counterfeit identification performance attribute (SIPA) sensitivity to changes in resolution of the image for features of an image is determined. The CIPA sensitivity for the features is used to choose at least one feature to determine whether the image on a sample is a counterfeit.

Abstract: In one embodiment of the present invention, a graphics processing unit (GPU) is configured to detect an object in an image using a random forest classifier that includes multiple, identically structured decision trees. Notably, the application of each of the decision trees is independent of the application of the other decision trees. In operation, the GPU partitions the image into subsets of pixels, and associates an execution thread with each of the pixels in the subset of pixels. The GPU then causes each of the execution threads to apply the random forest classifier to the associated pixel, thereby determining a likelihood that the pixel corresponds to the object. Advantageously, such a distributed approach to object detection more fully leverages the parallel architecture of the parallel processing unit (PPU) than conventional approaches. In particular, the PPU performs object detection more efficiently using the random forest classifier than using a cascaded classifier.

A first image position of a particle in the first image of the particles is identified, and then the first image position of the particle is correlated to a second image position of the particle in the second image using the plurality of video frames.
