Video Format

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 (Mitthögskolans 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

Enhancement Algorithm

According to the characteristics of infrared images, a contrast enhancement algorithm was presented. The principium of FPGA-based adaptive bidirectional plateau histogram equalization was given in this paper. The plateau value was obtained by finding local maximum and whole maximum in statistical histogram based on dimensional histogram statistic. Statistical histogram was modified by the plateau value and balanced in gray scale and gray spacing. Test data generated by single frame image, which was simulated by FPGA-based real-time adaptive bidirectional plateau histogram equalization. The simulation results indicates that the precept meet the requests well in both the image processing effects and processing speed

Uncooled Infrared Imaging

Uncooled infrared imaging system has been increasingly applied in both the national defense and various fields of national economy. Such popularity is attributed to many of its advantages, including small size, light weight, low energy-consumption and superior portability. However, as limited by the structure and the material of infrared detector and the manufacturing techniques, infrared images are plagued with low resolution and poor image quality. This paper mainly studies the uncooled infrared image processing based on the gray levels partition processing, gray levels stretching and histogram modification, it aims to enhance the visual effect of infrared image.
