Hierarchical projective invariant contexts for shape recognition

作者：

Highlights：

• We propose a new shape descriptor (HCNC) invariant to projective deformations.

• HCNC is compact with a hierarchical strategy, rendering efficient matching.

• HCNC is robust to noise, part-missing and articulated deformations.
