I have found the x and y co-ordinates of centroid of an image. I need to extract only the y-axis value and plot it against x=1:1:10. How can I extract the why axis value?
Code to find the centroid is in the comment below. Thanks

If anyone is looking for the solution you can do this if you have one centroid in the image
If you want to get the grid row and column numbers, you should plot the grid with predefined grid row and column width:
rowWidth = 52; % Grid row width in pixels
colWidth = 53; % Grid column width in pixels
[rows, columns, ~] = size(Image);for row = 1 : rowWidth : rows line([1, columns], [row, row], 'Color', 'r');endfor col = 1 : colWidth : columns line([col, col], [1, rows], 'Color', 'r');endTo get the the grid row and column numbers (assuming you have only one centroid):
% Get the row and column of the centroid (in grid units)
centroidGridCol = ceil(stat(1).Centroid(1) / colWidth);centroidGridRow = ceil(stat(1).Centroid(2) / rowWidth);See my Image Segmentation Tutorial where I demonstrate that: http://www.mathworks.com/matlabcentral/fileexchange/25157-image-segmentation-tutorial---blobsdemo--
