I used the regionprops function to find the coin's center point and mean intensity.

I want to find D4x and D4y based on the central points of the obtained coin (or perform horizontal / vertical axis 2D - plotting)

(ex. Point spread function)

The number of coins is so large that it is too slow to plot all of the centroids of the obtained coins.

Is there a function that can 2D plot the intensity of an image by part?

Because of the speed problem, it seems difficult to get all the coins through the for loop.

What speed problem? You can do it in a loop right?

I worded it wrong. This means that the number of coins is so large that it is too slow to plot all of the centroids of the obtained coins.
