• Abstract: We develop a new statistical ideal observer model that performs holistic visual search (or gist) processing in part by placing thresholds on minimum extractable image features. In this model, the ideal observer reduces the number of free parameters thereby shrinking down the system. The applications of this novel framework is in medical image perception (for optimizing imaging systems and algorithms), computer vision, benchmarking performance and enabling feature selection/evaluations. Other applications are in target detection and recognition in defense/security as well as evaluating sensors and detectors.

  We propose a new test framework which isolates the neural rendering network from the Neural Radiance Field (NeRF) pipeline.

Our approach offers the potential to create a comparative objective evaluation framework for NeRF methods.
