[D] Image classification detect small scratches with CNN

Hello Guys,

i want to classify images of microchips and detect, if there are scratches or cracks on them. The images show all the same microchip in the same position and are Black-White-Images. I made a CNN with 3 Conv Layer and 2 Dense Layer and only get around 87% val\_accuracy.

Is it possible to take a pretrained model with a Crack/Scratch dataset and use it? But the Datasets i saw, where images with the scratch or crack very big …
