矢量描述 meaning in Chinese

vector description

Meanwhile , advantages of the least calculation workload , the simple process , and the convenient for implementation are brought while switch states are described as space vectors in the - coordination system
利用-平面内的空间矢量描述开关组合状态，使得误差函数的计算工作量小、过程简单，易于实现。
In the basis of present technology , we provide our method . with our method , we first extract several low visual feature of the image , such as color , texture etc , and then we fuze the feature into a high dimensional vector ; sencond , we analyze the vector with pca method , which reduce the dimension of the vector ; and last we use the vector to classify the image
该方法的基本思路描述如下：首先，提取图像的多种视觉特征(如：颜色、纹理等) ，经融合得到一个高维矢量描述；然后，对该高维矢量描述作pca ( principalcomponentsanalysis )分析，以获取其中的主元，降低维数；最后，以降维后的矢量描述为基础，用于图片的分类系统。
