摘要
The image of ultrasonic televiewer logging often has a lot of abnormal points,and hence this paper proposes a new method for reducing outliers based on the TV-inpainting to solve the problem of extracting these outliers.The processing results show that the proposed method can effectively extract the outliers,ensure logging image integrity,and significantly improve image quality,which is of very important practical significance for processing the logging data.
