The advantages of geophysical images are not only straightforward and visual,but also lie in the fact that they can be processed by image processing methods so as to improve the capacities of solving geophysical and geological problems.In this paper,some kinds of geophysical images are described and the image processing methods applied in geophysics are introduced,from which pointed out that the techniques of image enhancement,reconstruction and analysis are now widely used in geophysical data processing,and synthetic analysis of multi source data based on image processing is a research trend.Considering the differences between geophysical image and ordinary image,the knowledge of problems that need to pay attention to in a process of image processing are given in the paper.Combing with GIS (Geographic Information System) gradually penetrated into geophysical study, the prospect of application of image processing to geophysics is described.
