LZ复杂度反映的是一个时间序列中，结合PCA的尺度不变特征变换(SIFT)算法，中介真值程度度量，基于中介真值程度度量的图像分。- LZ complexity is reflected in a time sequence, Combined with PCA scale invariant feature transform (SIFT) algorithm, The true extent of the value of the intermediary measure, measure the true extent of the agency based on the value of image segmentatio.
