Ed(s): K. Lee, Y. Matsushita, J. Rehg & Z. Hu
TL;DR:
This paper addresses the problem of X-to-X-occlusion-free object detection by utilizing an intuitive coupling-and-decoupling strategy, and compares the model with the state-of-the-art deformable part-based model (DPM) and obtain better detection performance.

Tracking Pedestrian with Multi-component Online Deformable Part-Based Model
In K. M. Lee, Y. Matsushita, J. M. Rehg, & Z. Hu (Eds.), Computer Vision – ACCV 2012 (pp. 664–676).
Ed(s): K. Lee, Y. Matsushita, J. Rehg & Z. Hu
TL;DR:
A novel online algorithm to track pedestrian by integrating both the bottom-up and the top-down models of pedestrian, which has three advantages compared with other models: it can efficiently generate match penalty maps of parts preserving the 2bit binary pattern, and can search over all possible configurations in an image in linear-time by distance transforms algorithm.

A stochastic graph grammar for compositional object representation and recognition
Pattern Recognition, 42(7), 1297–1307.
TL;DR:
A hierarchical generative model for representing and recognizing compositional object categories with large intra-category variance that combines the power of a stochastic context free grammar (SCFG) to express the variability of part configurations, and a Markov random field (MRF) to represent the pictorial spatial relationships between these parts.
