Quality assessment of image retargeting results is useful when comparing different methods. However, performing the necessary user studies is a long, cumbersome process. In this paper, we propose a simple yet efficient objective quality assessment method based on five key factors: i) preservation of salient regions; ii) analysis of the influence of artifacts; iii) preservation of the global structure...
Roughness of concrete pavement is partly due to cracks, potholes, road repairs and so on, therefore, pavement roughness is correlated to distress rate. However, the correlation is not clear, and has not been reflected in existing pavement evaluation models. Firstly, linear and nonlinear regression are used to analyze the relationships between international roughness index and pavement distress rate...
In this paper, using 16 days 250m MODIS vegetation index dataset, the relationship between eight vegetation indexes (VIs) and aboveground biomass in Gannan grassland of China, was analyzed. Based on their correlations, monitoring models of aboveground biomass was constructed, and then the aboveground biomass of the whole Gannan Autonomous Region and its every county were estimated. The results showed...
Being lack of the evaluation indexes system and evaluating method of domestic normal transit system's barrier-free service quality, there are not enough scientific principles for barrier-free planning, design, management and supervising of normal urban public transportation system. So, in this paper, an initial new evaluation indexes system of that mentioned above is set up, also, the definition and...
