Web6 de abr. de 2024 · Just want to point out that you don't need to match only contours and in fact the original paper dealt with non-binary images. Also the original paper proposes a very different distance calculation IIRC and J. Flusser et al have since proven in 90's and 06 papers IIRC that Hu's invariants are neither truly invariant nor complete. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
