Surely these would affect/require slightly different intrinsic matrix right? Especially given that the translational threshold in the metrix is pretty tight, or am I not understanding the intrinsic matrix correctly.</p>\n\n<p>And also there are images that are flipped, for example ID_04ea999fc and ID_000372ced. Yes it is certainly doable to find out all the images that are flipped and flip them back, but why???</p>",
