Low level image processing is the base of localization. The paper discusses time domain filtering and frequency domain filtering according to the noise disturbance in the surrounding images.
低层视觉图象处理是视觉定位的基础，针对环境图象存在噪声干扰的特点，文章分别从时域和频域上分析了图象滤波的方法。
Filtering algorithms base on space, frequency, wavelet and time have been introduced to reduce noises caused by environmental and lighting conditions in the video image sequences.
针对视频图像存在由于环境、光照等原因所引起的噪声的特点，应用基于空间域、频域、小波域和时域等多种去噪方法。
If you feed the output from your test rig into a real-time computer filtering software and mount everything to a solid base, you would have a system as capable as any available.
如果你把输出从你进入一个实时计算机试验台的一切过滤软件，安装一个坚实的基础，你也应该有一个系统作为任何可用的能力相同。
