    摘要: Systems and methods for visualization of medical image data with localized enhancement. In one implementation, image data of a structure of interest is resampled within a predetermined plane to generate at least one background image of the structure of interest. In addition, at least one local image is reconstructed to visually enhance at least one local region of interest associated with the structure of interest. The local image and the background image are then combined to generate a composite image.

    摘要: Described herein is a technology for facilitating computer-aided detection and image understanding. In one implementation, an input set of training images of a target structure, such as an anatomical structure, is received. The input set of training images is spatially realigned to different landmarks to generate multiple bags of training images. At least one of the multiple bags comprises substantially all the training images in the input set, but realigned to a landmark. The multiple bags of training images may be used to train a spatial ensemble of detectors, which can be employed to generate an output result by automatically detecting a target structure in an input image.

    摘要: In a method of 3D object detection, a learning procedure is used for feature selection from a feature set based on an annotated image-volume database, generating a set of selected features. A classifier is built using a classification scheme to distinguish between an object location and a non-object location and using the set of selected features. The classifier is applied at a candidate volume to determine whether the candidate volume contains an object of interest.

    摘要: A system and method for tracking an object is disclosed. A video sequence including a plurality of image frames are received. A sample based representation of object appearance distribution is maintained. An object is divided into one or more components. For each component, its location and uncertainty with respect to the sample based representation are estimated. Variable-Bandwidth Density Based Fusion (VBDF) is applied to each component to determine a most dominant motion. The motion estimate is used to determine the track of the object.
