Hello, At the moment I am using GIMP developer version 2.9.7 and I am very impressed with the results of Levin-Matting engine. However, the calculation with this engine is very time-consuming. I believe that the calculation time can be significantly reduced if the steps in the selection process can be modified. For now, the following steps are necessary: 1) make a rough selection around the object that needs to be selected 2) use brush to paint foreground, unknown and background area. 3) press ENTER to start selection algorithm 4) if you are not satisfied with the result, make further foreground, unknown and background corrections with a brush. The problem with this fourth step is that the algorithm is started automatically after each brush stroke which increases the calculation time unnecessarily. Proposal: 1) make a rough selection around each object that needs to be selected (If you want to select several objects that are not connected to each other, it would be good to be able to make several independent selections at once) 2) use brush to paint foreground, unknown and background area. 3) press ENTER to start selection algorithm 4) if you are not satisfied with the result, make further foreground, unknown and background corrections with a brush. 5) press ENTER to start selection algorithm again. or even better: 1) use brush to paint foreground, unknown and background area. 2) press ENTER to start selection algorithm 3) if you are not satisfied with the result, make further foreground, unknown and background corrections with a brush. 5) press ENTER to start selection algorithm again. The first step is not necessary, because after that initial selection you have possibility to select the foreground, background and unknown with a brush anyway.
