本文提出用二维小波变换对水平切片进行图象处理的方法，通过把水平切片分解为不同尺度的图象，根据解释需要，提出在某尺度下的隐含信息，以便提高解释精度。
In this paper, a method of image processing of horizontal slices by two-dimensional wavelet transform is proposed. By dividing horizontal slices into images of different scales, implicit information at a certain scale is proposed according to the needs of interpretation so as to improve the accuracy of interpretation.
