- 对提高可见光通信传输速率的研究，并提出了使用LDPC编码来降低干扰。-In order to increase a transmission rate, the transmitter is composed of plural LEDs and sends digital information by independently controlling brightness of them, which is called parallel transmissions. The r
An-Image-Defogging-Algorithm
- 提出了一种基于雾气遮罩减除的图像去雾算 法。首先对降质图像平滑滤波以估计其亮度分量，对亮度分量求均值得到均匀分布的雾气遮罩，并结合退 化图像获取与场景深度信息相关的雾气遮罩。在对数域中从降质图像中减除获得的雾气遮罩，即可得到 场景的反射图像。对反射图像进行自适应的对比度拉伸，可以得到最终的去雾结果。-Proposed algorithm based on the image to fog mist mask subtraction. First, the degraded im
