Grassfire algorithm

The grassfire transform can be abstracted to suit a variety of computing problems. It has been shown that it can be extended beyond the context of images to arbitrary functions. This includes applications in energy minimization problems such as those handled by the Viterbi algorithm, max-product belief … See more In image processing, the grassfire transform is the computation of the distance from a pixel to the border of a region. It can be described as "setting fire" to the borders of an image region to yield descriptors such as … See more The algorithm below is a simple two pass method for computing the Manhattan distance from the border of a region. Of course there are … See more A region's skeleton can be a useful descriptor, because it describes things such as the symmetry of the region as well as subparts, depressions and protrusions. It also provides a way of relating the interior of a region to the shape of the boundary. In the … See more • Topological skeleton • Distance transform See more WebNov 3, 2024 · 3 3. Use a proper data structure for your grid or at least add an abstraction so you can quickly access a given (i,j) pair. For a recursive algorithm you have to pass in the distance so far as an extra parameter (eg waveAlgorithm (int** arr, int i, int j, int distance) ). You should then only proceed if the given (i,j) pair is in bounds of your ...

WebMay 6, 2024 · In the Wavefront/Grassfire algorithm, we scan across the array, finding the current wave (number) and all the neighbors will get that same number + 1. To illustrate this, we will show a simple maze. Here the 255 represent our barriers. 1 represents our target. Let’s run a Wavefront. Our current wave is 1. Step 1, find the neighbors to 1 WebGrassfire Thinning. The Grassfire effect is used to erode images by a set amount.
