update from origin
We update the computation of the self-similarity for gallery images. The new similarity considers the correlation of local features with same visual word.

The self-similarity computation in function DetermineDBImageSelfSimilarities() of inverted_file.h is modified. This modification can achieve an improvement of recall on the Pittsburgh data set.
However, we only evaluate the modification in our implementation where the local feature is extracted in a different way from the original paper.
More experiments should be performed on the original data and San Francisco data set to verify this modification is effective.
