Abstract: Highlights•Proposing a block partitioning strategy to extract local information.•Modeling local information as affine hull for image set classification.•Developing a cooperative operator to integrate different information as a whole.•Proposing a linear regression model embedded with the cooperative operator.•Proposing an efficient optimization algorithm to solve the model.
