MATLAB: Grid through a center point

#grid #center point

I need do a grid that adaptes to my structure like the figure in attach. However i need establish a metric for the point in red that varies for different cases to stay always in the center of a bin, so I need construct the grid through the coordinates of this point. Can you help me?

Thanks.

I'm not sure what you're asking. Do you want that blue region to be like a solid region, and then find the centroid of it??? If so, use poly2mask(), activecontour(), bwconncomp(), and then regionprops().

It a frequency histogram

X = randn(1000,1);
hist(X)

It "bins" the input data and returns the number of data values that value in each bin.

You can get the actual counts and bin center with the optional output arguments:

 [counts,centers] = hist(X);

I already answered something very similar to this from you recently.

Why don't you try bwdist(). It will find the distance of every point to the closest background point. If you really need the distance that is not the shortest, but along some arbitrary line you draw, then you'll have to use improfile().
