| 摘 要： | 针对远程教育视频图像传输过程中,由于传输距离过长,图像传输信号会受到复杂外界环境因素的影响,造成视频图像传输信号衰减,导致远程教育视频图像中包含大量的非线性噪声,造成图像不清晰。提出了一种基于非线性滤波的远程教育视频图像清晰化处理算法。对远程教育视频图像中的噪声特征进行分类处理,利用非线性滤波算法进行去噪处理,从而实现了远程教育视频图像去噪处理。实验证明,这种算法能够避免由于传输距离过长导致的远程教育视频图像中存在大量噪声的缺陷,提高了远程教育视频图像清晰度。 |
| 关 键 词： | 远程教育 视频图像 去噪处理 |

| Abstract: | In the remote education video image transmission process,because the transmission distance is too long,image transmission signal will be affected by external environment factors influence the complex,causing the video image transmission signal attenuation,and lead to the remote education video image contains a lot of noise.Puts forward a nonlinear filtering algorithm based on the distance education video image denoising processing method.Distance education video to the noise of the image processing characteristics of classification by using nonlinear filtering method to deal with the noise,thus fulfilling the remote education video image denoising processing.Experiments show that the algorithm can avoid the transmission distance is too long to remote education video image,there are a lot of noise defect,make remote education video image denoising processing accuracy. |
| Keywords: | distance education video images to deal with the noise |
