An internal function that uses a concavehull to determine the bounds of the muscle based on grayscale values on each image and determines how many boundary voxels are within a set distance from the selected image point.
boundary.check(images, new.zero.image, new.startx, new.starty, bound.buffer, cutoff)The number of boundary voxels within bound.buffer distance of the proposed point.
A vector of image names in the working directory, created using list.files
The image plane being considered
The x coordinate of the considered point
The y coordinate of the considered point
The number of voxels a point can be distant from the boundary
The grayscale value under which voxels will be treated as black
