Infrared Image Real-time Enlargement System Design Based on FPGA

摘要

Low contrast and shortage of gray levels are two main characteristics of infrared image. According to the characteristics of infrared image, a simple and practical video format MHIVF (Mitthogskolans Interlaced Video Format) and conversion technique are introduced. This kind of video format can simplify the infrared image processing. Infrared image real-time enlargement system based on FPGA is designed and the bilinear interpolation algorithm is selected for image enlargement. The experiment results show that the designed system has a lower complexity and image processing speed is obviously increased.
