基于DWT和DCT的图象水印算法,过程简单,效果一般(DWT and DCT-based image watermarking algorithm, the process is simple, the effect of general)

某统计局欲了解第三产业总产出、中间消耗、增加值、劳动者报酬、生产税净额、固定资产折旧、营业盈余之间的关系，根据下面给出的数据建立相应的模型并进行分析，同时又因为变量数目过多影响对其的综合分析，要求对他们进行主成分分析；(Bureau of Statistics For a third of total industrial output, intermediate consumption, value added, workers compensation, production, net of tax, depreciation of fixed assets, the relationship between the operating surplus, in accordance with the following data given by the model and the corresponding analysis, at the same time, because too many variables affect the number of comprehensive analysis of its request for them to carry out principal component analysis )
