Video object extraction is a key technology in content-based video coding.A novel video object extracting algorithm by two Dimensional (2-D) mesh-based motion analysis is proposed in this ***,a 2-D mesh fitting the original frame image is obtained via feature detection algorithm. Then,higher order statistics motion analysis is applied on the 2-D mesh representation to get an initial motion detection *** post-processing,the final segmenting mask is quickly *** hence the video object is effectively *** results show that the proposed algorithm combines the merits of mesh-based segmenting algorithms and pixel-based segmenting algorithms,and hereby achieves satisfactory subjective and objective performance while dramatically increasing the segmenting speed.

生态效率关乎经济与生态之间的双重问题,要保证在实现社会经济正常发展的同时将环境影响控制到最小程度。CO_2等温室气体的排放作为造成全球气候变暖的主要产物,成为改善全球环境问题的焦点。土地利用转型在一定程度上影响着土地生态,并从土地的投入和产出方面影响土地生态效应,分析其影响机理将有助于最小化土地利用成本,最大化土地生态价值。论文运用混合方向性距离函数模型和Global Malmquist-Luenberger(GML)指数,将CO_2排放量作为生态效率的非期望产出指标,构建土地利用转型投入和产出指标体系,测算2006—2014年江苏省13个城市在土地利用转型背景下的生态效率及环境全要素生产率增长状况,并对全要素生产率变动进行分解,以期缓解经济快速增进带来的生态环境问题。研究结果表明:CO_2过度排放以及能源过度消耗,使得很多城市普遍存在生态低效率;2006—2014年江苏省总体平均生态效率值为0.827,若能够充分利用当前技术水平,资源强度和污染排放强度在平均意义上可以提高17%;江苏省生态效率变化区域差异明显,生态效率存在空间关联性和集聚效应;环境全要素生产率增长呈现地域不均衡性,纯技术进步是影响环境全要素生产率增长变动的重要影响因素;技术规模变化的区域差异幅度最大,是构成环境全要素生产率增长差异的重要因素。
