摘要： Methods and systems for modeling infrastructure elements in three dimensions are disclosed. An example method can comprise a computer receiving information from a database. The received information can comprise structural information describing a form of a structure and condition information describing a condition of the structure. The computer can create a graphical model of the structure based on the structural information. The computer can further determine, based on the condition information, a condition of one or more portions of the structure, and can color the one or more portions of the structure based on the determined condition.

摘要： An embodiment of the invention provides a method of analyzing an image of a user to determine whether the image is authentic, where a first image of a user's face is received with a camera. Four or more two-dimensional feature points can be located that do not lie on the same two-dimensional plane. Additional images of the user's face can be received; and, the at least four two-dimensional feature points can be located on each additional image with the image processor. The image processor can identify displacements between the two-dimensional feature points on the additional image and the two-dimensional feature points on the first image for each additional image. A processor can determine whether the displacements conform to a three-dimensional surface model. The processor can determine whether to authenticate the user based on the determination of whether the displacements conform to the three-dimensional surface model.

摘要： Methods and systems for detecting an object part location based on an extended date-driven detection. A specific relevance value between configurations of parts with respect to a set of training images annotated with annotating objects can be defined. A similarity learning algorithm can be applied with respect to the parts to obtain a similarity function based on the similarity between the part configurations. The similarity learning algorithm receives a set of positive pair having similar part configuration and a negative pair having different configuration and returns the similarity function that tends to assign a high score to new positive pairs and a low score to negative pairs. A similarity between a new image and the training images can be measured utilizing the learned similarity function to obtain a neighbor image and a visible and/or non-visible part location with respect to the image can be predicted based on the neighbor image.

摘要： A method generates a three-dimensional map of a region from successive images of the region captured from different camera poses. The method detects feature points within the captured images and designates a subset of the images as a set of keyframes each having camera pose data and respective sets of measurement data representing image positions of landmark points detected as feature points in that image. The method also includes performing bundle-adjustment to generate bundle-adjusted landmark points by iteratively refining the three dimensional spatial positions of the landmarks and the camera pose data associated with at least a subset of the keyframes. And for a feature point, not corresponding to a bundle-adjusted landmark point, detected at an intervening image which is not a keyframe and present in another intervening image which is not a keyframe, the method generates a non-bundle-adjusted point corresponding to that feature point and derives a camera pose.

摘要： An image processing apparatus includes an acquisition unit, a first detection unit, a selection unit, and a correction unit. The acquisition unit acquires an image including a target object having a plurality of parts. The first detection unit detects a candidate region of each of the plurality of parts of the target object included in the acquired image using a previously learned model. The selection unit selects, based on the candidate region detected by the first detection unit, a first part having relatively high reliability and a second part having relatively low reliability from among the plurality of parts. The correction unit corrects the model by changing a position of the second part based on the first part selected by the selection unit.

摘要： An approach is provided for classifying objects that are present at a geo-location and providing an uncluttered presentation of images of some of the objects in an application such as a map application. The approach includes determining one or more regions of interest associated with at least one geo-location, wherein the one or more regions of interest are at least one textured three-dimensional representation of one or more objects that may be present at the at least one geo-location. The approach also includes processing and/or facilitating a processing of the at least one textured three-dimensional representation to determine at least one two-dimensional footprint and three-dimensional geometry information for the one or more objects. The approach further includes causing, at least in part, a generation of at least one two-dimensional image representation of the one or more regions of interest by causing, at least in part, a projection of three-dimensional texture information of the at least one textured three-dimensional representation onto the at least one two-dimensional footprint. The approach also includes causing, at least in part, a classification of the one or more objects based, at least in part, on the at least one two-dimensional image representation and the three-dimensional geometry information.

摘要： A computing device segments an image into a plurality of segments, wherein each segment of the plurality of segments has a segment location and a set of pixels that share visual characteristics. The computing device determines an initial set of bounding boxes for the image based on the plurality of segments. The computing device determines a reduced set of bounding boxes based on combining bounding boxes of the initial set of bounding boxes, the reduced set of bounding boxes corresponding to one or more objects in the image, each of the one or more objects having an object class and an object location.

摘要： Systems and methods search pixels of source images and compare them to pixels of templates. Best matches correlate to objects in the image. That environmental conditions impact the appearance of objects, best matching scores suffer under poor lighting and other adverse conditions. Improving scores includes augmenting traditional correlation techniques with object features extracted from the source image and matching them to templates corresponding to the features. Certain embodiments contemplate corrupting pixels of image templates corresponding to objects with pixels extracted from the source image corresponding to features. Representative features include corners, edges, ridges, points/regions of interest, etc. Other embodiments note augmented correlation as a computing application and computing devices therefore, including cameras for capturing images and displaying results to users.
