Web2 de nov. de 2016 · A hierarchical signature scheme is an N -time signature scheme that uses other hash-based signatures in its construction. Let \varGamma = (\varUpsilon _ {N_0}, \varUpsilon _ {N_1}, \ldots , \varUpsilon _ {N_ {l-1}}) denote a hierarchical signature scheme with l levels. The public key Z for \varGamma is the output of K_0 (that is, the … WebDownload scientific diagram Hierarchical Hash Tables from publication: Shape Descriptor Based Document Image Indexing and Symbol Recognition In this paper we present a …
WebCentroid-based hierarchical hashing method. This approach assumes topic distributions can be partitioned into k clusters where each topic belongs to the cluster with the nearest mean score. It is based on the k-Means clustering algorithm, where k is obtained by adding 1 to the number of hierarchy levels. WebHashing has been an important and effective technology in image retrieval due to its computational efficiency and fast search speed. The traditional hashing methods usually learn hash functions to obtain binary codes by exploiting hand-crafted features, which cannot optimally represent the informati …
