ppm格式的图片转换成为bmp格式图片的转换工具。

SIFT算法由D.G.Lowe 1999年提出，2004年完善总结。后来Y.Ke将其描述子部分用PCA代替直方图的方式，对其进行改进。 2 SIFT 主要思想 SIFT算法是一种提取局部特征的算法，在尺度空间寻找极值点，提取位置，尺度，旋转不变量。 -a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene. The features are invariant to image scale and rotation, and are shown to provide robust matching across a a substantial range of affine distortion, change in 3D viewpoint, addition of noise, and change in illumination. The features are highly distinctive, in the sense that a single feature can be correctly matched with high probability against a large database of features from many images.

:在同一受试者,针刺不同穴位可引起相同部位脑功能区激活,不同人针刺相同穴位激活的脑功能区有一定差异,针刺效 果可能并非通过单一脑功能区,而是通过有功能联系的多个脑功能区所形成的一个复杂的流动性网络的相互作用而实现的。-: In the same subjects, acupuncture points can cause the same parts in different functional areas of brain activation, different people the same acupuncture points to activate certain areas of brain function differences in effects of acupuncture may not be through a single brain functional areas, but rather through a functional linkages of multiple brain functional area formed by a complex interplay of mobile network implementation.
