How can I calculate the density at the point x[i], y[i], so I can be able to plot the contour of the image?

I have an image with several points and I labeled them so I can know their coordinates (x,y).
Now I have a list of coordinates such as:

obj [0]: (1.5918367346938775, 806.42857142857144)
obj [1]: (5.5131578947368425, 860.59539473684208)
obj [2]: (0.0, 853.0)
(...)
obj [1183]: (1722.6078431372548, 1575.8725490196077)
obj [1184]: (1725.7272727272727, 330.72727272727275)
obj [1185]: (1726.4285714285713, 335.85714285714283)
obj [1186]: (1727.0, 327.0)

How can I be able to plot the the density map of the image in Python?

Density of what? All you have is a set of points.

With the set of points I could calculate the average distance between the 3 closests points and then make a density map?

So you probably need to sort the points into some order so you can then take any set and count how many exist within a certain area. Alternatively create a 2D array of whatever detail level you want, and plot the points into it.

Do you mean the relation between points and no-point in the area described by the coordinates?

yes!
