Hi there,
I've uploaded the files. You can find them under the following link(https://www.dropbox.com/sh/2r3lj83tmyxc8kb/AAA5z56hnN6HH9AWxSWSgw8ca?dl=0). In the meanwhile I trying to improve the preprocessing of my workflow and changed some parameters. I could reach approx. 38% error with the alex_net worklow and approx. 26 % error with a simple alternative random forest workflow.
I think that my worklfow has got two major issues. First of all my database isn't big enough... but I'm working on extending the database. It takes a lot of time to simulate processes to get new images. The second issue in my opinion is the bad preprocessing. If you have a closer look to the images u can see that there are sometimes more particle on the image than the main metal particle. I think it might influence the feature calculator.
I tried to preprocess the images with several things... First of all I started to use the global thresholder + labeling filter to get rid of the background and smaller pixel. The Problem is that there are sometimes bigger particle than the main particle... Moreover the thresholder node excludes some pixels from the main particle and declares it as background. I mean i could use the interactive annotator node to segment it by myself but that would take ages and I think it is not the sense of the thing. Could you help me please?
best regards
christian
