Abstract: Methods for estimating and predicting tooth wear based upon a single 3D digital model of teeth. The 3D digital model is segmented to identify individual teeth within the model. A digital model of a tooth is selected from the segmented model, and its original shape is predicted. The digital model is compared with the predicted original shape to estimate wear areas. A mapping function based upon values relating to tooth wear can also be applied to the selected digital model to predict wear of the tooth.

Abstract: Systems and methods for image based location estimation are described. In one example embodiment, a first positioning system is used to generate a first position estimate. A set of structure façade data describing one or more structure façades associated with the first position estimate is then accessed. A first image of an environment is captured, and a portion of the image is matched to part of the structure façade data. A second position is then estimated based on a comparison of the structure façade data with the portion of the image matched to the structure façade data.

Abstract: Systems and methods of enhancing the resolution of digital terrain models (DTM) for location-based applications and analyses. The DTM enhancement process takes the signature of the input image (e.g., via the input image and a noise surface file with similar characteristics as the sensor used to capture the input image) and applies it to the DTM without including large features such as buildings. The disclosed methods include utilize a process similar to that used for enhancing a DSM based on mapping the changing intensity from the image file to changes in elevation in the DSM using a regression over a local neighborhood of pixels. Further, the disclosed methods do not rely on information about the sensors and are extendable to be able to utilize any types of images. Additionally, the disclosed embodiments are sensor agnostic and can be applied on any type of image collected by any type of sensor.

Abstract: A system and method of designating regions of interest for surveillance cameras is disclosed. The system enables definition of regions of interest simultaneously across multiple cameras. This is useful when the cameras are positioned to monitor the same region of interest within their scenes. Each camera monitors image data for designation of regions of interest, stores the regions of interest, and analyzes the image data from the cameras based on the regions of interest. Preferably, each camera has an integrated analytics system for analyzing the image data based on the regions of interest. A setup process between a user device (e.g. mobile phone) and the cameras enables definition of the regions of interest. In embodiments, the regions of interest are defined in response to the cameras tracking either the user device or an optical device as an operator moves the devices to outline the regions of interest within the scene.
