“…Image "compression" means the reduction of the total number of effective pixel values that are multiplexed off of the focal plane array (FPA). The full resolution a)-image was generated by the CHAMP infrared scene generation program [10], [11]. Both a) and d) images (see Figure 1.a and Figure 1.d) contain a point-target and a resolved target image.…”

In our previous papers, the FPGA-based processing package and the co-processor board have been introduced for numerous commercial and military applications including motion detection, optical flow, background velocimetry, and target tracking. The processing package is being continually upgraded by new point-and areaapplied algorithms for a variety of real-time digital video camera systems including foveal sensors based on Nova's Variable Acuity Superpixel Imager (VASI™) and Large Format VASI™ (LVASI™) technologies.This paper demonstrates the FPGA-based processor for high frame-rate target detection in a cluttered background using variable acuity sensors. For the 1024 x 1024 pixel LVASI™ Focal Plane Array (FPA), the proposed target-detection algorithm increases the frame rate from 4 Hz for the full resolution mode up to 450 Hz for the foveal mode while maintaining full field of view and target-detection performances on cluttered backgrounds that are comparable with detection performances at the full resolution mode.

“…Both figures contain a point-target and a resolved target. The full resolution image on the left was generated by the CHAMP infrared scene generation program [3], [4], and contains 16384 pixel values (128x128). The size of the full resolution frame has been reduced from 16384 pixel values to 718 pixel values in the "compressed" superpixellated image on the right.…”

Nova Sensors produces miniature electronics for a variety of real-time digital video camera systems, including foveal sensors based on Nova's Variable Acuity Superpixel Imager (VASI™) technology. An advanced imageprocessing package has been designed at Nova Sensors to re-configure the FPGA-based co-processor board for numerous applications including motion detection, optical, background velocimetry and target tracking. Currently, the processing package consists of 14 processing operations that cover a broad range of point-and area-applied algorithms. Flexible FPGA designs of these operations and re-programmability of the processing board allows for easy updates of the VASI™ sensors, and for low-cost customization of VASI™ sensors taking into account specific customer requirements. This paper describes the image processing algorithms implemented and verified in Xilinx FPGAs and provides the major technical performances with figures illustrating practical applications of the processing package.
