Bobst challenge

What it does

Find print errors on photos, even if the photos are not all exactly in the same position

How I built it

Using python with numpy and opencv for image manipulation, using key point on the print to align the images and compare the pixels to an average value calculated with 1000 pictures

Challenges I ran into

align the photos, print may not be on the same place on the paper, differentiate errors from noise

Accomplishments that I'm proud of

the alignment algorithm functions quite well

What I learned

manipulate images programmatically

What's next for error finder

Noise is often interpreted instead of the actual signal
