Jan 14, 2023 · I'm trying to count the number of connected zeros such that the shape created by these zeros is surrounded entirely by 1s (and hence, not on the boundary).
In displaying pictures, 0 is white and 1 is black; thus, in binary images, the background is white and objects are black. We will also assume that pictures are ...
Figure 3.15a shows a binary image of a watch gear. The watch gear has four holes inside of the main object and is surrounded by a number of teeth, which are ...
An object without holes shrinks to a minimally connected stroke, and an object with holes shrinks to a connected ring halfway between each hole and the outer ...
For 2D objects, the Euler number is the number of objects minus the number of holes. Notice that if a neighborhood of 8 connected pixels (2-connectivity) is ...
The binary object treated is a square with a square hole. We first use a set of initial phases to determine the symmetry of the object.
This MATLAB function performs a flood-fill operation on background pixels of the input binary image BW, starting from the points specified in locations.
This is a classical problem in Homology Theory which tries to calculate the number of connected components and the representative curves of the holes of these.
