The modeling of a city’s evolution is one of the most exciting fields in urban studies research. The interest of such a model lies more in the past than the future: understanding how a city was made rather as opposed to how it might evolve. Such a model can necessitate expertise from numerous fields. From urban network analysis to spatial organisation and social patterning, modeling is a matter...

The relationship between fashion history should co-exist. Taking Jianghan Road Pedestrian Street Block as an example, this paper analyzes how to deal with balance old new construction, integrate fresh sense humanistic into block, discusses va...

Land use maps are very important references for the urban planning and management. However, it is difficult and time-consuming to get high-resolution urban land use maps. In this study, we propose a new method to derive land use information at building block level based on machine learning and geo-tagged street-level imagery – Google Street View images. Several commonly used generic image featu...

The Urban Surveillance Systems generate huge amount of video and image data and impose high pressure onto the recording disks. It is obvious that the research of video is a key point of big data research areas. Since videos are composed of images, the degree and efficiency of image compression are of great importance. Although the DCT based JPEG standard are widely used, it encounters insurmoun...
