Can you please describe a little bit more about what you are trying to detect for each feature? Like, a paragraph per topic. Maybe some pictures. If I have a good idea of what you want to do I can tell you then the methods you need to use to do it.

1. It's possible to measure the size of things... using color tracking if you can detect something via color.
2. Dented areas are darker (under the right lighting) than non-dented areas. You can compare color histograms.
3. Color will not be smooth. Same kind of thing like above.
4. If dirt specs are small then this is hard. If they are large areas then this is possible. Using the same methods as above.
35. Isn't this the same as a dent?
Nyamekye,
