Parallel Modelling of Neural Operators for Pattern Recognition - PAMONOP Network (1994-96)
Biologically inspired approaches to machine vision problems were studied
in this EU PAMONOP Network (Parallel Modelling of Neural Operators for Pattern Recognition). The problems studied range from motion detection
based on insect vision to pattern analysis and optical flow calculation based on complex Gabor filters
as a model of the primary cortical image representation in mammalian visual systems. Complex Gabor image representations were studied and applied to set up models of neural
operators which are capable of yielding low- and medium-level structural information. Extensive comparative studies will be carried out on alternative methods for effective multi-motion segmentation and representation of face invariants for face representation and recognition. The project involves 9 European partners in which QMW coordinated the UK group including QMW (Gong and Liddell), Cambridge (Daugman) and Sussex (Buxton). Our primary areas of interest are face recognition, optical flow and neural nets. In particular, we addressed the following problems:
Temporal (dynamic) sequences for facial recognition; determination of the appropriate degrees of freedom underlying alternate representations.
Tracking facial features using Gabor wavelet representations (demodulation and predictive coding).
Explicit comparison of mechanisms, such as Bayesian network updating versus current neural networks.
The role of neuro-anatomical reciprocating feedback mechanisms in the prediction and reconstruction of visual perception.
