针对图像数据的72维HSV颜色特征,对数据集的本征维概念进行了有意义的扩展,在此基础上提出了一个新的降维机制。实验证明,该降维算法是行之有效的。
Aiming at the 72-dimensional HSV feature of image color, this paper made a significant improvement to the intrinsic dimensionality of data set at first. Then it proposed a new dimension reduction approach. Experiments show that this method is efficient.
