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. http://15462.courses.cs.cmu.edu/fall2024content/lectures/11_geometryprocessing/11_geometryprocessing_slides.pdf

If processing techniques make use of operators defined in the real plane, an approximation problem arises. Very frequently, the image is a "black-and-white" image: in this case, one is usually interested in obtaining a smooth approximation of the boundary between "inside" and "outside." WebApr 28, 2024 · This chapter presents an iterative smoothing technique for polygonal approximation of digital image boundary. The technique starts with finest initial segmentation points of a curve. The contribution of initially segmented points toward preserving the original shape of the image boundary is determined by computing the … fnv carry computer
