I am trying to make a deep learning classification on the gear part you can see in the images. The contrast is high and almost binary. I want to classify the images where the circle located closest to the centre circle is left of the circle located furthest from the centre circle as the good part.
When this is mirrored (the circle located closest to the centre circle is right of the circle located furthest from the centre circle) the part needs to be classified as bad.
The parts can be rotated over a range of 360 degrees. The parts are found beforehand and cropped with the centre of the part as the centre of the image, which makes translation not a problem. The parts do not vary in scale.
I am using Keras with TensorFlow as Backend. I have 3600 input images, with 1800 good and 1800 bad images, where the parts are rotated. I have build some simple CNNs with three convolutional layers up to the VGG16 model, without getting past 0.5 accuracy.
My knowledge on different kind of models is limited and therefore I don't know which arcitecture would suit my problem best. Can anyone help me with some guidance on the kind of model I could use or to tell me if this is at all possible like this?
If more information is needed please let me know.
