Visualization to help choose sigmas for meanshiftim.
Displays the original image I, and prompts user to select a point on the image. For
given point, calculates the distance (both spatial and range) to every other point in
the image. It shows the results in a number of panes, which include 1) the original
image I, 2) Srange - similarity based on range only, 3) Seuc - similarity based on
Euclidean distance only, and 4) overall similarity. Finally, in each image the green
dot (possibly occluded) shows the original point, and the blue dot shows the new mean of
the window after 1 step of meanshift.
INPUTS
I - MxN image for display
X - MxNxP data array, P may be 1 (X may be same as I)
sig_spt - integer specifying spatial standard deviation
sig_rng - value specifying the standard deviation of the range data
show - [optional] will display results in figure(show)
EXAMPLE
I=double(imread('cameraman.tif'))/255;
meanshiftim_explore( I, I, 5, .2, 1 );
