to enhance HoG to detect walking people as well as to discriminate between single walking subject, groups of people and<br />
vehicles with a detection rate of 100%. Furthermore, the results revealed the potential of our method to be used in visual surveillance<br />
systems for identity tracking over different camera views.<br />

This paper aims at detecting preceding vehicles in a variety of distance. A sub-region up-scaling scheme significantly raises<br />
far distance detection capability. Three frame pipeline structures involving object predictors are explored to further enhance<br />
accuracy and efficiency. It claims a 140-meter detecting distance along proposed methodology. 97.1% detection rate with<br />
4.2% false alarm rate is achieved. At last, the benchmark of several learning-based vehicle detection approaches is provided.<br />

Dynamic Hand Pose Recognition using Depth Data<br />

Hand pose recognition has been a problem of great interest to the Computer Vision and Human Computer Interaction community<br />
for many years and the current solutions either require additional accessories at the user end or enormous computation<br />
time. These limitations arise mainly due to the high dexterity of human hand and occlusions created in the limited view of<br />
the camera. This work utilizes the depth information and a novel algorithm to recognize scale and rotation invariant hand<br />
poses dynamically. We have designed a volumetric shape descriptor enfolding the hand to generate a 3D cylindrical histogram<br />
and achieved robust pose recognition in real time.<br />

A Hierarchical GIST Model Embedding Multiple Biological Feasibilities for Scene Classification<br />
Han, Yina, Xi’an Jiaotong Univ.<br />

We propose a hierarchical GIST model embedding multiple biological feasibilities for scene classification. In the perceptual<br />
layer, spatial layout of Gabor features are extracted in a bio-vision guided way: introducing diagnostic color information,<br />
tuning the orientations and scales of Gabor filters, as well as the spacial pooling size to a biological feasible value. In the<br />
conceptual layer, for the first time, we attempt to build a computational model for the biological conceptual GIST by kernel<br />
PCA based prototype representation, which is specific task orientated as biological GIST, and also in accordance with the<br />
unsupervised learning assumption in the primary visual cortex and prototype similarity based categorization in human cognition.<br />
Using around $200$ dimensions, our model is shown to outperform existing GIST models, and to achieve state-ofthe-art<br />
performances on four scene datasets.<br />

Road Network Extraction using Edge Detection and Spatial Voting<br />

Road network detection from very high resolution satellite images is important for two main reasons. First, the detection<br />
result can be used in automated map making. Second, the detected network can be used in trajectory planning for unmanned<br />
aerial vehicles. Although an expert can label road pixels in a given satellite image, this operation is prone to errors. Therefore,<br />
an automated system is needed to detect the road network in a given satellite image in a robust manner. In this study, we propose<br />
a novel approach to detect the road network from a given panchromatic Ikonos satellite image. Our method has five<br />
main steps. First, we apply a nonlinear bilateral filtering to smooth the given image. Then, we extract Canny edges and the<br />
gradient information as local features. Using these local features, we generate a spatial voting matrix. This voting matrix in-<br />
