Accident elements detection based on improved DPM

Deformable Part Models (DPM) has high detection accuracy in the image detection algorithm, while it is at the expense of complex calculation and slowly running speed. In order to improve the development of its application, the algorithms of the weighted PCA (MPCA) and fast level locating are also proposed, MPCA can reduce the model parameters by reducing the dimensions of HOG features and the fast level locating can locate the object's level in the feature pyramid fast. This paper also presents the optical accidents elements detection for the scene of the accident which can be used in varying environment. Our results show that the detection of the accidents elements obtained are sufficiently robust to the changing scene of accident and its speed increases significantly.
