This paper discusses the fundamental role of the doors and windows of the building, and the dominant roles such as spatial organization and control of light, and to study the recessive function of windows and doors from aspects of the psychological impact, cultural significance and decoration. After exploring the characteristics of modem windows and doors, it studies the design elements of modem windows and doors and summed up the features that the initiative to make use of the environment. Basic from three levels as the basic form of design; windows and buildings, and the social and natural environment of the unified design; doors and windows to take the initiative to study the nature.展开更多

Processing speed and detection accuracy of the face detection have been improved continuously. This paper describes a novel method of fast face detection with multi-scale window search free from image resizing. We adopt statistics of gradient images (SGI) as image features and append an overlapping cell array to improve detection accuracy. The SGI feature is scale invariant and insensitive to small difference of pixel value. These characteristics enable the multi-scale window search without image resizing. Experimental results show that processing speed of our method is 3.66 times faster than a conventional method, adopting HOG features combined to an SVM classifier, without accuracy degradation.展开更多
