enter image description here

i compare them in order know if it's same figure or not (especially inside triangle). took in sift , surf feature it's doesn't work on type of picture (it find matchning point whereas 2 picture different,especially inside).

i hear svm don't know if have implement type of problem.

do have idea ?

thank you

you use linear or circle hough transform in case tell lot image differences.
