Abstract
At least first and second digital images of the sample are acquired having different focal heights relative to a platform on which the cells are disposed. A contrast matrix is produced having elements computed in dependence upon the difference between the values of the corresponding pixels in the first and second images. A phase matrix is produced by convolution of the contrast matrix with a predetermined distance matrix. The phase matrix is used to assess characteristics of the sample, such as the presence of cells in the sample or the heights of cells in the sample.
