| 摘 要： | 红外图像模式识别系统,由图像预处理、特征提取及模式分类组成.基于红外图像模式识别的图像预处理,包括滤波降噪、目标增强、图像分割等处理.滤波降噪有邻域平均、中值和Butterworth低通等滤波方法.目标增强可通过微分及Butterworth高通滤波完成,图像分割可采用阈值分割技术实现.故综合比较各种处理方法,采用两次均值滤波及拉普拉斯算子、阚值分割技术,较好实现了红外图像模式识别的预处理.

| Abstract: | The infrared pattern recognition system consists of image preprocessing, feature extraction and pattern classification. The image preprocessing based on infrared image mode recognition includes noise reduction, image enhancement and image segmentation. The filter noise reduction method includes neighborhood average method, median method and Butterworth low-pass method. The target enhancement could be realized through the differential coefficient and Butterworth high pass filter; the image division could be realized by adopting threshold division technology. So, compared with varied processing method, the two-mean filter, the laplacian operator and the threshold division technology could realize the infrared image pattern recognition oreprocessing better. |
