Composite filtering strategy for improving distortion invariance in object recognition

Ahmed B. Awan, Saad Rehman, Asim D. Bakhshi
2018 IET Image Processing  
Correlation-based pattern recognition filtering methods such as the eigenextended maximum average correlation height (EEMACH) filter is considered an effective tool in object recognition applications.  ...  However, these approaches require exclusive training for all possible distortions including in-plane as well as out-of-plane rotation, scale and illumination variations.  ...  Conclusion and future work This paper suggests a composite filtering strategy for CPR with significantly better recognition capability.  ...
