The software released here implements a C++ library for object detection in images. The main algorithm is based on the detection method proposed by Felzenszwalb et al. [1].

The input of the detector is a single image, where the detection procedure is carried out. Depending on the target object class, a different object model is used. Such model is a computational description of an object class. It is stored in a binary file with .mat extension. Some of these model files are included in the released package.

LibPaBOD is built on top of two libraries: OpenCV [2] and MatIO [3]. Among other things, OpenCV library is used to handle images using the IplImage structure. In addition, CvMat and CvMatND structures are much more functional in order to perform matrix operations. MatIO library is a basic point. It allows that LibPaBOD can read the object model file and load it into memory.
