摘要： A method detects a target in a sequence of radar images, wherein each image is partitioned into a grid of cells, and wherein each cell has a corresponding position in an image coordinate system associated with a location in a world coordinate system. For each most recent image in a sliding temporal window of images, intensities of each cell are determined, and the subset of the cells having highest intensities is stored as a set of current needles. A set of hypotheses, obtained by using a state transition model and corresponding maximum limits, is determined for the current set of needles and appended to a set of queues. The hypotheses for the previous sets of needles to the corresponding set of queues are updated, and a maximum likelihood in the set of queues are selected to detect the location of targets.

摘要： A tumor is tracked in sequences of bi-plane images by generating a set of segmentation hypotheses using a 3D model of the tumor, a bi-plane geometry, and a previous location of the tumor as determined from the pairs of biplane images. Volume prior probabilities are constructed based on the set of hypotheses. Seed pixels are selected using the volume prior probabilities, and a bi-plane dual image graph is constructed using intensity gradients and the seed pixels to obtaining segmentation masks corresponding to tumor boundaries using the image intensities to determine a current location of the tumor.

摘要： A method detects an object left-behind in a scene by updating a set of background models using a sequence of images acquired of the scene by a camera. Each background model is updated at a different temporal scales ranging from short term to long term. A foreground mask is determined from each background model after the updating for a particular image of the sequence. A motion image is updated from the set of foreground masks. In the motion, image, each pixel has an associated evidence value. The evidence values are compared with a evidence threshold to detect and signal an object left behind in the scene.

摘要： A method generates a distance map from an image including a set of pixels arranged in a Euclidian n-space. The set of pixels includes a subset of background pixels and a subset of foreground pixels. The distance map stores a distance value for every corresponding background pixel to a nearest foreground pixel. A set of scan lines having different directions are defined. The scanning of the set of pixels along each scan lines is performed by moving from a current pixel to a next pixel. The scanning of each scan line includes: making the next pixel the current pixel; initializing a counter to zero when the current pixel is one of the foreground pixels and the next pixel is one of the background pixels; incrementing the counter by one when the next pixel is one of the background pixels; and assigning the counter as the distance corresponding to the current pixel if the current pixel is one of the background pixels, and repeating beginning with the making step.

摘要： A method tracks an object in a sequence of frames of a video. The method is provided with a set of tracking modules. Frames of a video are buffered in a memory buffer. First, an object is tracked in the buffered frames forward in time using a selected one of the plurality of tracking module. Second, the object is tracked in the buffered frames backward in time using the selected tracking module. Then, a tracking error is determined from the first tracking and the second tracking. If the tracking error is less than a predetermined threshold, then additional frames are buffered in the memory buffer and the first tracking, the second tracking and the determining steps are repeated. Otherwise, if the error is greater than the predetermined threshold, then a different tracking module is selected and the first tracking, the second tracking and the determining steps are repeated.
