An improved method of 3D contours extraction is presented in this paper. To simplify and improve the two steps operation of traditional wavelet algorithm, an improved method for 2D contours extraction called 2D-IMCE is developed based on stationary wavelet transform. This method can gain complete, fine and continuous contours by only one step through automatically percolating non-contour points without thresholding and human-machine interactions. To inherit superiority of 2D-IMCE, an extended way of it for 3D contours extraction named Fuse-2D-IMCE is derived. It utilizes satisfactory 2D contours to approximate 3D ones based on fusion operation. Firstly, industrial CT volume data are divided into three groups of slices corresponding to three mutual perpendicular directions. Secondly, in each slice group, 2D contours are extracted by 2D-IMCE. Finally, 3D contours are obtained by fusing all 2D ones of three directions. Experimental results demonstrate that the Fuse-2D-IMCE method can effectively extract 3D contours from industrial CT volume data.
