boundary.check {GoodFibes} | R Documentation |
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)
images |
A vector of image names in the working directory, created using list.files |
new.zero.image |
The image plane being considered |
new.startx |
The x coordinate of the considered point |
new.starty |
The y coordinate of the considered point |
bound.buffer |
The number of voxels a point can be distant from the boundary |
cutoff |
The grayscale value under which voxels will be treated as black |
For internal use only
The number of boundary voxels within bound.buffer distance of the proposed point.
