Image data of consecutive frames from a camera is obtained, with a first frame being taken during an emission of infrared light directed at a scene to be captured by the camera and a second frame being taken without an emission of infrared light. The consecutive frames provide a dynamic control image of the captured scene. The image data may be used to support photometric sampling techniques used in building geometric models for subject recognition in camera imagery in variable lighting environments.

Abstract: A high dynamic range video processing method performs merging and tone mapping techniques after a Bayer filter mosaic technique is performed and then converts it to red green blue (RGB) at the end as opposed to converting into RGB at the beginning and then performing merging and tone mapping after. The HDR processing is performed on Bayer-mosaic images and no de-mosaicing and color space conversions are required. The merging procedure has two modes: full-reset merging and LDR-updated merging. The first mode, full-reset merging, creates an HDR frame once the system has all image frames captured. The second mode, LDR-updating merging, means that any new HDR frame is obtained by an updating of a previous HDR frame with a new LDR frame data.
