摘要
文中介绍了一种实时图像增强方法。针对长波红外图像的特点,考虑电路的实现方便性,图像增强方法由1×5伪中值滤波算法、基于人眼视觉效应的高通滤波算法和改进的直方图均衡算法三部分组成。该方法具有平滑图像噪声,增强长波红外图像细节,保持图像边缘信息,且自适应调节图像的灰度范围等特点。文中给出了图像增强方法的电路实现框图和模拟实验结果。
A real-time enhancement method of long-wavelength IR image is proposed. According to the characteristics of long-wavelength IR image and convenience of real-time processing, the method consists of 1×5 pseudo-median filter, vision based on high-pass filter and modified histogram equalization. It is available for smoothing the noise, enhancing the detail, conserving the edge and automatically adjusting the gray level in long-wavelength IR image. The principle of hardware implement is discussed. The experimental results are given in detail.
