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

  • 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.
