Method and apparatus for extracting contour lines from a pattern obtained in image processing, which makes it possible to obtain contour lines real-time with a high speed and, moreover, can easily make use of hardware. In embodiments of the invention a simplified discrimination method for ...
We propose a new model for active contours based on a geometric partial differential equation. Our model is intrinsec, stable (satisfies the maximum principle) and permits a rigorous mathematical analysis. It enables us to extract smooth shapes (we cannot retrieve angles) and it can be adapted ...

It can be used to plan strategies in many rescue and security applications. The paper deals with imaging of the inner and outer building contours from the outside using through the wall UWB radar. The whole processing chain for obtaining the contours of a scanned building is explained. The ...

Build and run. The found contour property values are displayed as follows. This image shows the results of the bounding rectangle, rotated bounding rectangle and minimum enclosing circles. (Red: bounding rectangle; Green: rotated bounding rectangle; Blue: minimum enclosing circle) ...
Use imfill to fill any holes in the regions in mask. If a region touches the image borders, then activecontour removes a single-pixel layer from the region, before further processing, so that the region does not touch the image border. To get faster and more accurate results, specify an ...
activecontouruses the Sparse-Field level-set method, similar to the method described in[3], for implementing active contour evolution. References [1] T. F. Chan, L. A. Vese,Active contours without edges. IEEE Transactions on Image Processing, Volume 10, Issue 2, pp. 266-277, 2001. ...
