Hi,
After segmenting my image with watershed method, I should use performance evaluation methods. There is IoU, rand index etc .. and therefore I need the following information: false positives, false negatives, true positives, true, negatives. So I decided to calculate pixel by pixel if it matches shapefile. But I didn't understand how to transform the shapefile into tiff to be able to do this. Do you know how to do it?

You could use the evaluateSemanticSegmentation function to evaluate different performance metrics which you require.
