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 ...
Contour line is the main linear feature on topographic maps. Extraction of contour lines is tedious and time-consuming process, and is still an interesting problem. A novel method for extraction of contour lines from paper-based topographic maps is presented in this paper. In our approach, we firstly segment color topographic maps for achieving the binary image of brown color contour lines. The...
Knowing of the water table around the region and access to its contour maps is one of the most important planning tools for withdrawal underground aquifers and implementing civil projects. Generally, by using the piezometric wells in the region and different methods of estimation, the water table determined. Limitation of these methods is the inability to estimate water table on different days ...
