Web29 sep. 2024 · My goal is to create a bounding box around the non-zero pixel value region of my image.I would perform some algorithm later on which I would like to restrict within the bounding box. I was wondering if it is possible to create a bounding box without reducing the size of the image. The arbitrarily oriented minimum bounding box is the minimum bounding box, calculated subject to no constraints as to the orientation of the result. Minimum bounding box algorithms based on the rotating calipers method can be used to find the minimum-area or minimum-perimeter bounding box of a two-dimensional convex polygon in linear time, and of a three-dimensional point set in the time it takes to construct its convex hull followed by a linear-time computation. A three-dimension…
