Geodesic Distance Histogram Feature for Video Segmentation [PDF]
, 2017 This paper proposes a geodesic-distance-based feature that encodes global information for improved video segmentation algorithms. The feature is a joint histogram of intensity and geodesic distances, where the geodesic distances are computed as the shortest paths between superpixels via their boundaries.

Beat histogram features from NMF-based novelty functions for music classification [PDF]
International Society for Music Information Retrieval Conference, 2015 In this paper we present novel rhythm features derived from drum tracks extracted from polyphonic music and evaluate them in a genre classification task. Musical excerpts are analyzed using an optimized, partially fixed Non-Negative Matrix Factorization (

Efficiently matching sets of features with random histograms [PDF]
Proceedings of the 16th ACM international conference on Multimedia, 2008 As the commonly used representation of a feature-rich data object has evolved from a single feature vector to a set of feature vectors, a key challenge in building a content-based search engine for feature-rich data is to match feature-sets efficiently. Although substantial progress has been made during the past few years, existing approaches are still
