Upgrade your surveillance, security or situation awareness system to reveal unseen detail and improve the appearance of your video, using RFEL’s Non-linear Image Contrast Enhancement (NICE™) technology. NICE is a hybrid FGPA and software solution, optimised for System-on-Chip (SoC) devices such as the Xilinx® Zynq®-7000.
- Maintains operation as scene visibility deteriorates.
- Both low-light and daylight enhancement for a versatile solution.
- Low latency of <1ms for human-in-the-loop applications.
- Rapid adaption (<100ms) to changes in illumination.
- Support of full HD at high frame rates.
- The NICE module can be combined with other RFEL IP modules in a single hardware device.
The versatility and low resource usage of NICE means that it can provide product differentiation for a huge range of video applications. NICE can dramatically optimise the contrast of the displayed video, irrespective of changes of illumination or atmospheric conditions.
Good image contrast is critical for human perception as it aids the interpretation of images and reduces reaction times, thereby increasing the effectiveness of video surveillance and border control.
NICE also offers improved situation awareness, which is important for the control of vehicles and in combat situations, where a rapidly changing degraded visual environment (DVE) can threaten security and safety. Generic inspection and screening tasks, such as those needed for manufacturing or medical applications, may also benefit from NICE’s high-speed enhancement techniques.
NICE provides a cost eff ective solution to improving both the quality and operational robustness of a vision system. Human visual perception is primarily based on intensity and so the correct management of scene brightness and contrast can make profound visual diff erences to the quality of your video images. NICE is a relatively simple processing operation, but its benefi ts are far from basic.
The NICE algorithm is cleverly implemented to optimally utilise the high-speed, low power FPGA processing resources, but also the embedded CPU cores, of state of the art system-on-chip (SoC) devices, such as the Xilinx Zynq-7000. The result is a highly efficient and flexible embedded processing engine that adds competitive advantage to your video capability. Engineering consultancy services are available to assist in integration of the IP, or RFEL sales can be contacted to discuss how NICE can be supplied as a plug-in system-on-module (SoM), or as a fully integrated sub-system for turn-key integration.
