I am starting with AI, training, detection and classification of small objects like loosened nut, bolts etc on a railway track. What should be the ideal way to collect dataset ( images )?
1. Does background matters in pictures, shall I use multiple background
2. Shall all images come from same height but different angles, or varying height is also important.
3. Or top angle from various heights is more effective
And what should be the best way to train the model?
1. with any dataset, iteratively training the model, by manually correcting every incorrect inference
2. or using a very large dataset without iterations
