摘要： In various examples, object fence corresponding to objects detected by an ego-vehicle may be used to determine overlap of the object fences with lanes on a driving surface. A lane mask may be generated corresponding to the lanes on the driving surface, and the object fences may be compared to the lanes of the lane mask to determine the overlap. Where an object fence is located in more than one lane, a boundary scoring approach may be used to determine a ratio of overlap of the boundary fence, and thus the object, with each of the lanes. The overlap with one or more lanes for each object may be used to determine lane assignments for the objects, and the lane assignments may be used by the ego-vehicle to determine a path or trajectory along the driving surface.

摘要： A system and associated methods are disclosed for automatically detecting, tracking and classifying an at least one object, moving within an environment proximal to a structure, using a camera. In at least one embodiment, a processor receives a plurality of video frames as captured by the camera. For each of the video frames, the processor detects the presence of the at least one object within said video frame, creates a track for each of the at least one detected object, identifies each track as either an acceptable track or noise, classifies each of the acceptable tracks, and generates an at least one summary image that visually represents the at least one detected object within the environment proximal to the structure, allowing for validation and performance evaluation of the object detection, tracking, and classification process.

摘要： Systems and methods are described for generating images of synthesized bodies wearing a garment. For instance, a source image of a human or mannequin wearing a garment may be submitted to a synthesized human generation system. In response to receiving the source image, the synthesized human generation system may use a classifier to classify the image as depicting one or more body types or orientations. The synthesized human generation system may also apply segmentation to the source image to segment the garment pixels. The synthesized human generation system may then select one or more body generation machine learning models based on the classification of the source image. The synthesized human generation system may utilize the selected machine learning models to generate one or more output images of synthesized bodies that appear to be wearing the garment, using the segmented garment as input.

摘要： The embodiments of the present disclosure disclose an edge-guided human eye image analyzing method. A specific implementation of this method comprises: collect a human eye image as an image to be detected; obtain a human eye detection contour map; obtain a semantic segmentation detection map and an initial human eye image detection fitting parameter; performing an iterative search on the initial human eye image detection fitting parameter to determine a target human eye image detection fitting parameter; sending the semantic segmentation detection map and the target human eye image detection fitting parameter as image analyzing results to a display terminal for display. This implementation improves the accuracy at the boundary dividing the pupil-iris area, and increases the structural integrity of the ellipse resulted from dividing the pupil-iris area. In addition, the iterative search can achieve a more accurate ellipse parameter fitting result.

摘要： A retinal vessel shadow view optical coherence tomography (RVSV-OCT) image can be created by receiving, at an enhanced OCT processing system, volumetric OCT scan of a patient. The system can segment the volumetric OCT scan to determine layer boundaries and delineate a boundary of interest based on the determined layer boundaries of the segmented volumetric OCT scan. En face vascular information can be extracted to create an RVSV-OCT image by determining a first offset from the boundary of interest and a second offset from the boundary of interest; extracting volumetric data from an area between the first offset and the second offset to create a three-dimensional volume; and identifying a two-dimensional surface from the three-dimensional volume, the two-dimensional surface being the RVSV-OCT image. The RVSV-OCT image can be provided for analysis, for example, to evaluate retinal vascular disease in preterm infants at risk for retinopathy of prematurity.
