Beyond neighbourhood-preserving transformations for quantization-based unsupervised hashing

•A new type of non-rigid transformation is presented for quantization based hashing.•The proposed non-rigid transformation corrupts the neighborhood structure of data in favor of quantization.•The proposed method reduces dimensionality and quantization error simultaneously.•Unlike other methods, we...
