Abstract: An alignment method for high dynamic resolution imaging searches and detects features in an image and parameterizing the features. Then differently exposed images are compared by comparing the features. Additionally the method detects features in an image, performs shape adaptive filtering using scaling pyramids, determines trajectories, calculates a range of characteristics for each unit in the image, and compares characteristics of paired units to select or eliminate the pair. Paired unit characterization selects unit pairs, selects unit pairs by statistical analysis, performs cluster analysis, calculates alignment parameters, and performs additional correction of the alignment parameters. The brightness channel is used for objects detection.

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.
