# Is it possible to select a number of points to highlight points in an image?

I would like to ask you how I can fix a number of points to show in a picture. In the previous post (Is it possible to get the coordinates only for the highlighted points from an image?), JimB suggested a good solution to determine the contour of the image and get the coordinates of those points. It would be interesting to know if there is a way to select a certain number of points that can "draw" the image (for example, 10). I tried using MaxFeatures ->10 in the ImageCorners, but it randomly selects the points.

• You could try to play around with the radius and threshold parameters of ImageCorners to reduce the number of points in a more meaningful way. Of course, this is an indirect approach since you can't set the maximum number of points, but it should be better than randomly selecting a subset. – Lukas Lang Sep 23 '19 at 21:12
