摘要：We propose a deformable parts model attached the coarse to fine detection methods to improve the detection speed. General when we meet the complex target structure, image changes, background interference problems, contour information of the target problems are often difficult to accurately describe. In order to solve the problem, we propose a hierarchical model: first we introduce the Conditional Random Fields (CRF) in the low-layer to fuse sorts of features which can obtain the target candidate region for high-layer that auxiliary to provide the appearance feature; in high-level we molding the contour features of the model and deformable parts model as the underlying detector, the model training and testing use of coarse to fine inference, so it will not only improve the detection speed but also improve the accuracy rate .The experiments on the PASCAL 2007 dataset show that the model flexibility, the universal recognition results are accurate and stable.
