Human Detection in IR

Many human detection algorithms are able to detect humans in various environmental conditions with high accuracy, but they lack the ability to give the exact region of where the human is located (usual detections as a bounding box). Our algorithm uses gradient information through the Histogram of Oriented Gradients and texture information through the center-symmetric local binary pattern. Various binning strategies help keep the inherent structure embedded in the features, which provide enough information for robust detection of the humans in the scene. Our algorithm is shown to create a better representation of the human detection in infrared imagery for analysis of scenes as compared to normal detection strategies.
