An improved implementation of infrared focal plane image enhancement algorithm based on FPGA

By analyzing the characteristics of infrared focal plane array image, an improved implementation of infrared focal plane image enhancement algorithm based on FPGA is proposed, with limited FPGA memory resources for gray-scale stretching. Experiment results show that the implementation is easy on FPGA with low FPGA memory without extra memory devices. Moreover, it is flexible and effective for improving gray contrast of the interested region of the image, and proved to meet the requirements of infrared focal plane detector for image enhancement showing great utility value.
