This paper proposes a method for generative learning of hierarchical random field models. The resulting model, which we call the hierarchical sparse FRAME (Filters, Random field, And Maximum Entropy) model, is a generalization of the original sparse FRAME model by decomposing it into multiple parts that are allowed to shift their locations, scales and rotations, so that the resulting model becomes...
In this paper, we learn a reconfigurable template for detecting vehicles and classifying their types. We adopt a popular design for the part based model that has one coarse template covering entire object window and several small high-resolution templates representing parts. The reconfigurable template can learn part configurations that capture the spatial correlation of features for a deformable...
This paper presents a novel framework for learning a generative image representation—the hybrid image template (HIT) from a small number (i.e., 3 \sim 20) of image examples. Each learned template is composed of, typically, 50 \sim 500 image patches whose geometric attributes (location, scale, orientation) may adapt in a local neighborhood for deformation, and whose appearances are characterized, respectively,...
