Extending dynamic range using ND filtering patterns on an 8-bit sensor

Show that capturing more information from an HDR scene using an ND filter pattern on a 1280 x 1024 pixel 8 bit monochromatic CCD sensor is feasible and compelling. Simulation is performed on appropriate HDR imagery using Matlab. An example HDR scene is selected consisting of a lit hallway with a doorway into a darkened room. The output consists of fused images with a simple digital cut and paste approach. A decision of continuing the masked sensor effort is made based on evaluation of the output scenes. The next steps would be further simulation as well as obtaining evaluation hardware.
