Short sea shipping has begun to receive attention from governments worldwide, as they seek to reduce traffic congestion and greenhouse gases. Despite a long coastline and its interest in international maritime affairs, the Canadian government had, until 2003, placed greater emphasis on resolving the issues of other transport modes. In July 2003, Canada and the United States signed a Memorandum of Cooperation on Sharing Short Sea Shipping Information and Experience. Subsequently, the federal government embarked on an assessment of short sea shipping through a series of workshops. This paper explores the key issues with respect to further development of short sea shipping from a Canadian perspective. It examines the critical limitations and impediments to further growth of short sea services in Canada and trans-border trade with the USA, and identifies a number of questions Canadian policymakers need to answer. 相似文献

采用改进分块方式的塔式方向梯度直方图(PHOG,Pyramid Histogram of oriented gradient)作为特征提取的方法,应用支持向量机(SVM,Support Vector Machine)算法作为分类器进行训练和检测.INRIA测试集上的测试结果表明,相对于采用传统HOG和PHOG特征表示方法,所提出的方法使分类检测正确率有了进一步提高. 相似文献
