WebJan 8, 2013 · Contours can be explained simply as a curve joining all the continuous points (along the boundary), having same color or intensity. The contours are a useful tool for shape analysis and object detection and recognition. For better accuracy, use binary images. So before finding contours, apply threshold or canny edge detection. WebMay 5, 2024 · I faced a problem when I firstly extracted the skeleton of the image then applied the polygonal approximation code. The problem is that when applying the 'bwboundaries' function on the skeleton image, some points are repeated so the polygon is not correct because of the repeated points.
WebTo draw the ROI interactively using the draw or drawpolygon function, position the cursor on the axes, click and drag the pointer to create the shape. As you draw the line, click to create a vertex. Double-click to finish drawing and close the polygon. The ROI supports the following interactivity, including keyboard shortcuts.
