python - how to match paper sheet by opencv -


i have kinds of paper sheet , writing python script opencv recognize same paper sheet classify. stuck in how find same kind of paper sheet. example, attached 2 pic. picture 1 template , picture 2 kind of paper need know if matching template. don't need match text , need match form. need classify same sheet in many of paper sheet.

i have adjust skew of paper , detect lines don't know how match lines , judge paper sheet same kind template.

is there 1 can give me advice matching algorithm?this paper sheet templatethis paper sheet need match templateneed matching lines

i'm not sure if such paper form rich enough in visual information solution, think should start feature detection , homography calculation (opencv tutorial: features2d + homography). there can try adjust 2d features problem.
