Figure showing the target location and templates created using \(D^{\prime }_{m}\) for key point j. The target location \(w^{D^{\prime }_{m}}\left (x^{\prime {m}}_{j},y^{\prime {m}}_{j},\theta =0\right)\) (a) is created at the location \(\left (x^{\prime {m}}_{j},y^{\prime {m}}_{j}\right)\) on image I. c, d, b, e and f shows the 5 templates \(w^{D^{\prime }_{m}}\left (x^{\prime {m}}_{j},y^{\prime {m}}_{j},\theta \right)\) created at \(\left (x^{\prime {m}}_{j},y^{\prime {m}}_{j}\right)\) on image \(D^{\prime }_{m}\) with θ=−10,−5,0, 5, 10 degrees respectively
