Object recognition using polar-exponential grid technique
Haiyan Zhang, Wang Dong-mu, Song Ke-ou · 2004
A new polar-exponential grid technique for object recognition is proposed in this paper. An object in the rectangular coordinate is mapped into the polar-log coordinate, and the closed profile of the object is transformed a one dimension curve. The structure of the curve has rotate, scale, translate invariance, which can be used in object recognition. Better recognition result using the structure invariant is got.
