We propose a speed up method for the Histograms of Oriented Gradients - Local Binary Pattern (HOG-LBP) based pedestrian detector. Our method is based on the two-stage cascade structure. In the first stage evaluation, instead of extracting the features from all the region inside the detection window like in the conventional method, we extract the features(More)
In this paper, we propose a simple and efficient face representation feature that adopts the eigenfaces of Local Binary Pattern (LBP) space, referred to as the LBP eigenfaces, for robust face recognition. In the proposed method, LBP eigenfaces are generated by first mapping the original image space to the LBP space and then projecting the LBP space to the(More)
In this paper, a high dynamic range (HDR) imaging method based on the stereo vision system is presented. The proposed method uses differently exposed low dynamic range (LDR) images captured from a stereo camera. The stereo LDR images are first converted to initial stereo HDR images using the inverse camera response function estimated from the LDR images.(More)
In this paper, we propose a bilateral tangent projection (BTP) algorithm to smooth a set of noisy data assumed to lie on a low-dimensional manifold. The data points are smoothed by a family of local tangent projections adaptively. The BTP algorithm utilizes not only the location information of the data point but also the fitness of the tangent space(More)
