Abstract: Systems and methods can be used to detect thermal anomalies in a target scene of an infrared image. Acquired thermal image data can be compared to a statistical thermal profile to detect thermal anomalies in the image data. Anomaly data based on the comparison can be used to generate an image representing locations and/or severity of detected anomalies. Systems can be used to acquire thermal image data for generating and/or updating statistical thermal profiles for use in anomaly detection processes. Auxiliary measurement devices can provide measurement data representative of one or more parameters of the target scene. The measurement data can be used to select from a plurality of possible statistical thermal profiles associated with the target scene to best match the current parameters of the scene.

Abstract: Identification of reflective surfaces as being associated with optical threats is disclosed. A first laser signal is emitted from a first laser system at a first wavelength and a first emission circular polarization orientation. A first signal reflection of the first laser signal from a reflective surface at the first wavelength having a first return circular polarization orientation that is different from the first emission circular polarization orientation is detected. A first return quantification of the first signal reflection, based at least in part on an amount of circular polarization of the first signal reflection, is determined. It is determined that the reflective surface is associated with a threat optic based at least in part on the first return quantification.

Abstract: Various embodiments of the present invention relate generally to systems and methods for analyzing and manipulating images and video. In particular, a multi-view interactive digital media representation (MVIDMR) of a person can be generated from live images of a person captured from a hand-held camera. Using the image data from the live images, a skeleton of the person and a boundary between the person and a background can be determined from different viewing angles and across multiple images. Using the skeleton and the boundary data, effects can be added to the person, such as wings. The effects can change from image to image to account for the different viewing angles of the person captured in each image.
