What is the Best Way for Extracting Meaningful Attributes from Pictures?
Liangchen Liu, Arnold Wiliem, Shaokang Chen +1
Automatic attribute discovery methods have gained in popularity to extract sets of visual attributes from images or videos for various tasks. Despite their good performance in some…
Random Projections on Manifolds of Symmetric Positive Definite Matrices for Image Classification
Azadeh Alavi, Arnold Wiliem, Kun Zhao +2
Recent advances suggest that encoding images through Symmetric Positive Definite (SPD) matrices and then interpreting such matrices as points on Riemannian manifolds can lead to in…
Matching Image Sets via Adaptive Multi Convex Hull
Shaokang Chen, Arnold Wiliem, Conrad Sanderson +1
Traditional nearest points methods use all the samples in an image set to construct a single convex or affine hull model for classification. However, strong artificial features and…
