摘要
针对传统图像增强技术处理红外图像的不足,文章提出了一种自适应分段线性增强算法,并使用FPGA对此算法进行了实现。该算法的核心思想是把原始图像自适应的分成背景区间、过渡区间和目标区间三个区间,并对这三个区域分别进行线性变换,视觉效果达到了最佳状态。测试结果表明,此算法硬件逻辑资源少,并且能进行实时处理,具有广泛的应用空间。
Traditional image enhancement lack of technical processing infrared image, the paper proposes an adaptive piecewiselinear enhancement algorithms, this algorithm and use the FPGA to achieve. The core idea of the algorithm is divided into the origi-nal image adaptive background interval, the transition interval and the target range of three intervals, and these three regions werelinear transformation, the visual effects to achieve the best state. The test results show that this algorithm hardware logic resourcesand real-time processing, and has a wide range of applications.
