Abstract
Imaging data or other data captured using a camera may be classified based on data captured using another sensor that is calibrated with the camera and operates in a different modality. Where a digital camera configured to capture visual images is calibrated with another sensor such as a thermal camera, a radiographic camera or an ultraviolet camera, and such sensors capture data simultaneously from a scene, the respectively captured data may be processed to detect one or more objects therein. A probability that data depicts one or more objects of interest may be enhanced based on data captured from calibrated sensors operating in different modalities. Where an object of interest is detected to a sufficient degree of confidence, annotated data from which the object was detected may be used to train one or more classifiers to recognize the object, or similar objects, or for any other purpose.
