Object identification in Opencv -


when take 2 images of same object different distances, appear of different sizes. how can compare , find out similar objects both images using opencv?

i can think of 2 possible approaches:

either compare images @ different scales. artificially decrease size of 1 of images , compare images if objects had same scale. take best result scales.

the other option use scale invariant features, scale of object not matter. sift popular example such feature.
