I have a NxN matrix defining the FOV of a camera. Approximately in the middle of FOV is an object that generates a height profile. I want to be able to move the centroid of the object to the exact center of the FOV matrix. I really don't care about the NaNs created by the translation of object. I will fill the NaNs generated by this translation to zeros. What is the best way to accomplish this.Thanks in advance.

I'd first segment the image to find the object. This really depends on what the object looks like. Then you can get a new image (not a live one though) that has the object at the center by using imtranslate().

Thanks for the quick response. Let me try it and I will let you know how it works.

在 MATLAB Online 中打开

Use

props = regionprops(mask, 'Centroid');
hold on;
% Plot red crosses at the centroid location(s).
for k = 1 : length(props)
    plot(props(k).Centroid(1), props(k).Centroid(2), 'r+', 'MarkerSize', 20, 'LineWidth', 2);
end
