Furthermore, because of wavelet transformation’s unique ability of multi-resolution and direction selection (like that of human eyes), it has replaced DCT transformation in JPEG2000 to become the image de-correlation transformation standards.
加上小波变换特有的与人眼视觉特性相符的多分辨率分析及方向选择能力，已在JPEG2000中取代DCT变换成为图像去相关的变换标准。

As long as the forces of selection stay constant, natural selection canpush evolution in one direction and produce sophisticated structures insurprisingly short times.
只要选择的影响力存在，自然选择就能把进化向一个方向推进，在出乎意料的短时间内产生复杂的结构。
Natural selection blew in the same direction - i.e., favored the same sets of characteristics - for, at most, three years in a row.
显然自然选择趋向了同一方向——即选择了相同的特性，而这种选择至多连续3年。
Model selection is an important research direction in SVM.
模型选择是支持向量机一个重要的研究方向。
