How to extract product label from a sequence of 306 product images?


I have 360 pictures of a supplement bottle. I want to extract product label out of those pictures. Is there anything that could do this?

I would imagine the software would need to project series of images onto a cylinder, align them, and then recognize and extract the label.

Feels like I will need to write the solution myself, but figured I will ask before I start tackling the problem.

stitch the images together (sift,orb) and apply a perspective transform.

if the images are uniform enough in style you can then probably crop them all at once with mask coordinates.

opencv/imagemagick will handle all of it.

if the images aren't uniform enough to crop them all at once, consider the use of a 'lazy susan' style vertical rotisserie, take all the photos from the same plane, easy post-processing.
