| 摘 要： | 红外探伤图像存在着对比度低、含噪声高的特点，导致判读和识别缺陷困难等问题。提出了基于高频强调滤波法的红外探伤图像增强方法。该方法在突出高频分量的同时，能保持经过高通滤波后丢失的低频分量，达到图像增强的目的。试验结果表明，采用高频强调滤波法对红外探伤图像进行处理，提高了图像的对比度和峰值信噪比，有效抑制了噪声的干扰。

| Abstract: | Infrared test image has low contrast and high noise,which results in difficulties in reading and recognizing defects difficultly.In order to solve the problems,image enhancement method based on high-frequency emphasized filtering for infrared test is presented.After high-pass filtering filtered,the method emphasizes on high-frequency components and also keeps lost low-frequency components,and finally realizes image enhancement.The result shows that the method improves image contrast and Peak Signal to Noise... |
