Read images into rows of a matrix.
imageListToMatrix(imageList, mask, sigma = NA, epsilon = 0)
imageList | A character vector containing a list of image files to read, in order - these are image objects, not file names. |

epsilon | threshold value determining what is included in the mask |
A matrix containing the masked data, the result of calling
as.numeric(image, mask)
on each input image.
