Convolutional Neural Network Ensemble Learning for Hyperspectral Imaging-based Blackberry Fruit Ripeness Detection in Uncontrolled Farm Environment
Chollette C. Olisah, Ben Trewhella, Bo Li +5
Fruit ripeness estimation models have for decades depended on spectral index features or colour-based features, such as mean, standard deviation, skewness, colour moments, and/or h…
Consensus-Threshold Criterion for Offline Signature Verification using Convolutional Neural Network Learned Representations
Paul Brimoh, Chollette C. Olisah
A genuine signer's signature is naturally unstable even at short time-intervals whereas, expert forgers always try to perfectly mimic a genuine signer's signature. This presents a…
Understanding Unconventional Preprocessors in Deep Convolutional Neural Networks for Face Identification
Chollette C. Olisah, Lyndon Smith
Deep networks have achieved huge successes in application domains like object and face recognition. The performance gain is attributed to different facets of the network architectu…
Expressing Facial Structure and Appearance Information in Frequency Domain for Face Recognition
Chollette C. Olisah, Solomon Nunoo, Peter Ofedebe +1
Beneath the uncertain primitive visual features of face images are the primitive intrinsic structural patterns (PISP) essential for characterizing a sample face discriminative attr…
