AerialImageClassificationMethodBasedonFractalTheor
- 提出一种基于分形理论和BP 神经网络的航空遥感图像有监督分类方法。该方法尝试将航空图像 的光谱信息和纹理特征相结合。它首先将彩色航空图像由RGB 格式转化为HSI 格式,然后,根据亮度计算分 数维、多重分形广义维数谱q-D( q) 和“空隙”等基于分形的纹理特征,同时加入归一化的色度和饱和度作为光 谱特征,采用BP 神经网络作为分类器。通过对彩色航空图像的分类实验,结果证实该方法行之有效。-Based on fractal theory and BP neural network
GMSK
- GMSK是高斯滤波的最小频移键控的简称，基本的工作原理是将基带信号先经过高斯滤波器成形，再进行最小频移键控(MSK)调制。由于成形后的高斯脉冲包络无陡峭边沿，亦无拐点，因此频谱特性优于MSK信号的频谱特性。-GMSK Gaussian filter is the smallest FSK abbreviation, the basic working principle is to base-band signal to pass Gaussian filter shape, and then
