This paper reports a real-time coarse-to-fine pedestrian detection method which is based on edge factor and Histogram of Oriented Gradient (HOG). In this method, first, the edge factor of detect window is used in the coarse detection, and then HOG combined with linear SVM (HOG/linSVM) is used in fine detection. The HOG/linSVM is one of the most popular(More)
Auto-focusing is an important problem for various imaging systems. A good focus measure, or evaluation function, is critical for the accomplishment of this task. Some evaluation functions are introduced. Analysis is done on evaluation functions using global data such as the squared image gradient magnitude of the whole image, asserting that these approaches(More)
