WebApr 6, 2024 · Only the last value are being stored in for loop. I just need to have a and c store array of numbers rather than store the last number. I need to sample from [a,c] and a should be something like [0 0.5 1 1.5...] and c should be [0.5 1 1.5 2...] but as of right now a and c just take the last values, 5 and 20. WebBW2 = imfill(BW,locations) performs a flood-fill operation on background pixels of the input binary image BW, starting from the points specified in locations. BW2 = imfill( BW , locations , conn ) fills the area defined by locations , where conn specifies the connectivity.
WebAug 14, 2024 · Enter the flood-fill algorithm. The idea behind it is quite simple and resembles the functionality of the “ink bucket” of image editors; from a source pixel, all its neighbours contained in the same connected region are filled with the same value. This can be easily implemented using the usual graph search algorithms such as breadth-first ... WebDec 8, 2024 · You need to modify the flood_fill function to return I. The other issue is that blobs is a logical array, and assigning any non-zero value to it yields a value of 1.
