I am ust a little bit confused about whether I should use a scatter plot or a 2D histogram to fit a mixture of Gaussians.
The problem is I have intensities from one image with 2 channels. For example, a RGB image but using just Red and Green channels. Then I plot the scatter plot and try to do a mixture of Gaussian fitting for the data points in the scatter plot.
However, thinking about the problem again, I am not sure if I should do a Mixture of Gaussian for the 2D histogram. Essentially, a 2D histogram is different from a 2D scatter plot, am I right?
Sorry about my confusion and thanks for your help.
