We deal with the problem of human facial expression recognition from digital images. A digital image is preprocessed for feature extraction using moment descriptors; then, it is represented in the product lattice (F 100,≥) of Intervals’Numbers (INs). Learning as well as generalization are carried out in space (F100,≥) by two different Fuzzy Lattice Reasoning (FLR) classifiers based on an inclusion measure function σ : F100 × F100 → [0, 1].We pursue both a stochastic optimization and a parallel implementation of the proposed techniques. Comparative experimental results on three benchmark data sets demonstrate a superior performance of the proposed FLR classification schemes.
