Simulating Light Source Motion in Single Images for Enhanced Perceptual Object Detection

The SIPHER technique uses mathematically-uncomplicated processing to impart interesting effects upon a static image. Importantly, it renders certain areas of an image more perceptible than others, and draws a human observer’s attention to particular objects or portions of an image scene. By varying coefficients of the processing in a time-ordered sequence, we can create a multi-frame video wherein the frame-to-frame temporal dynamics further enhance human perception of image objects. In this article we first explain the mathematical formulations and present results from applying SIPHER to simple three-dimensional shapes. Then we explore SIPHER’s utility in enhancing visual perception of targets or objects of military interest, in imagery with some typical backgrounds. We also explore how and why these effects enhance human visual perception of the image objects.
