    摘要： The present invention relates to annotating images. In an embodiment, the present invention enables users to create annotations corresponding to three-dimensional objects while viewing two-dimensional images. In one embodiment, this is achieved by projecting a selecting object onto a three-dimensional model created from a plurality of two-dimensional images. The selecting object is input by a user while viewing a first image corresponding to a portion of the three-dimensional model. A location corresponding to the projection on the three-dimensional model is determined, and content entered by the user while viewing the first image is associated with the location. The content is stored together with the location information to form an annotation. The annotation can be retrieved and displayed together with other images corresponding to the location.

    摘要： This invention is a niching optimization algorithm that provides multiple extrapolated points of a function, the maximum or minimum outputs, over one optimization run. Yet differently than existing niching algorithms, it locally ranks each local population, providing a multi-focus exploration with an equalized number of solutions inside each niche, and identifies the set of most efficient and distinct solutions, instead of the overall population of solution. As an optimization algorithm, it has broad application in artificial intelligence, and in the design of engineering systems such as aeronautical structures, etc. . . . . It also can generate a mesh for any dataset or function domain, grouping inputs by regions of similitude. Thus, it can generate a mesh for a FEM, and segment the domain of expensive metamodels, like artificial neural networks, Kriging models (KR), among others. Experiments demonstrated that with a response surface mesh, the overall training time is substantially reduced.

    摘要： A system and method are presented for estimating the orientation of a panoramic camera mounted on a vehicle relative to the vehicle coordinate frame. An initial pose estimate of the vehicle is determined based on global positioning system data, inertial measurement unit data, and wheel odometry data of the vehicle. Image data from images captured by the camera is processed to obtain one or more tracks, each track including a sequence of matched feature points stemming from a same three-dimensional location. A correction parameter determined from the initial pose estimate and tracks can then be used to correct the orientations of the images captured by the camera. The correction parameter can be optimized by deriving a correction parameter for each of a multitude of distinct subsequences of one or more runs. Statistical analysis can be performed on the determined correction parameters to produce robust estimates.
