A New Approach to Fast Contour Interpolation
نویسندگان
چکیده
This paper presents a new contouring approach which comes from the idea of morphology-based interpolation algorithm.. Three main steps are carried out for the recovering of the missing contours: firstly, a so-called difference image is formed from original two slice contours; secondly, shape deformation vectors of the contour points on the upper slice are calculated; thirdly, instead of the image based dilation and erosion operation, we directly calculate the points along the shape deformation vectors to generate the intermediate contour points. Compared to known interpolating methods, our approach utilizes the simplicity and robustness of morphology-based algorithm but overcomes its disadvantage of low speed.

Fast Distance Field Interpolation for Reconstruction of Surfaces from Contours
One simple and robust way to get a reconstruction of surfaces from a given contour stack dealing well with branching and other problems which are generally difficult to solve is based on the well known MC-algorithm. To overcome the staircase artefacts produced by the MC-algorithm Jones et. al. 3 proposed to use a distance field interpolation between the slices and to run the MC-algorithm on thi...
متن کاملAutomatic implementation of a new recovery coefficient for Reliable contour milling
In contour milling, to render the machining process more automated with significant productivity without remaining material after machining, a new recovery coefficient was developed. The coefficient was inserted in the computation of contour parallel tool paths to fix the radial depth of cut in the way to ensure an optimized overlap area between the passes in the corners, without residuals. Thu...
متن کاملSpatial Temporal Active Contour Interpolation for Semi-Automatic Video Object Generation
An active-contour-interpolation approach is proposed for semi-automatic video object generation. In this approach, user can de ne the contour of the same video object on multiple frames and the computer interpolates the missing contours automatically. Typical active contour model is adapted and the contour interpolation problem is decomposed into two directional contour tracking problems and a ...

Interpolation of Orientation : Axiomatic Approach and Applications
This paper develops an axiomatic approach of vector field orientation, seen as angles on the unit circle. Two operators will be singled out: the curvature operator, appearing in total variation minimisation for image restoration and inpainting/disocclusion, as a direct solution and the Absolutely Minimizing Lipschitz Extension (AMLE), already known as a robust and coherent scalar image interpol...
