Should unique vectors (SIFT descriptors) be used in K-Means Clustering?












0












$begingroup$


I'm doing image classification by extracting SIFT features, clustering them and then finding BOVW histogram and classifying.



I have around 180 training images from which I'm extracting SIFT descriptors. I need to cluster these features using k-Means clustering. Now, among the SIFT descriptors, some are duplicate. Before applying K-Means, should I remove these duplicate vectors or should I not? Or does it not make any difference?



Thanks!
