What tools are used when images are displayed in a scatter plot?
$\begingroup$
I have seen a lot of scatter plots where the data inside the scatter plot has come from images.
But an image is like a matrix. It has a height and a width. And a scatter plot only write out the data as dots.
Question:
Assume that I want to print a lot of images inside a scatter plot. What tools should I use then (except the plotting tool e.g MATLAB)?
Should I use mean, average? Should I use standrard deviation?
Image that we have three pictures classes in this plot. How could they describe ONE picture as just ONE dot? How is that possible?
