Dear All
I'm creating imcontourplots of grayscale SEM-images. Since I want to simplify the contourplots I thinking about removing points out of the array so that the contour is created with less data points. How can I remove points out of a imcontourplot?
Thank you in advance.

Hello Bram,
You can start by obtaining contour matrix and a handle to an hggroup object. For example, take the CreateContourPlotOfIMageDataExample in the "imcontour" documentation:
%This is the example
I = imread('rice.png');
imshow(I)
figure;
imcontour(I,3)
%Do this instead
I = imread('rice.png');
imshow(I)
figure;
[C,handle] = imcontour(I,3)
This provides a handle with the data used to create the image. You can use the following command to recontour the image:
>>contour(handle.XData,handle.YData,handle.ZData)
You can edit this data to remove points that you may not want or need.
