linecoords
Edge detection result should be enhanced using linear method like Median filter to
remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the
centre of the pupil by counting the number of black pixels (zero value) of each column and
row. Then get each row and column that has the maximum number of these black pixels.
Then determine the center by simple calculation according to the image coordinate to set it
correct on the image, consequently we can determine the radius of the pupil. Thus we can find
the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to
locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms
of circle and ellipse.

v_resample
V_RESAMPLE is a Matlab function implementing nonuniform data sampling. It resamples the input data at the specified, continuously variable sampling rate, which may be locally higher or lower w.r.t. the original rate. Aliasing terms are taken care of by appropriate smoothing.
