— We describe two methods by which foveated (variable resolution) images can be created using the techniques of compressive sensing (CS). Foveated sampling (FS) combines a linear shift-variant foveation filter with the CS measurement operator. Foveated sampling and reconstruction (FSR) combines the foveation filter with the CS measurement operator and also(More)
The development of the System Test Automation (STA) tool helps fill a gap in combined hardware and software test automation. STA is able to exercise a system's software via command-line or graphical interfaces, and simultaneously control equipment to exercise the system's hardware. Once developed, test sequences can be executed without human assistance.(More)
We present a method for computing dense stereo correspondences in calibrated monocular video by iteratively and stochastically sampling match quality values in the disparity search space. Most existing methods exhaustively compute local correspondence quality before searching for a globally optimal solution. Instead, we iteratively refine a correspondence(More)
We compare approaches for generating binary control signals for variable acuity superpixel imager (VASI™) cameras. We foveate a set of images using control signals generated by various halftoning approaches and then measure their performance via figures of merit (FOMs). We find that two novel approaches provide superior FOM values but inferior bandwidth(More)
