A Survey on Image Feature Descriptors

Abstract-Automatically assigning relevant text keywords to image is an important problem. Many algorithms have been proposed in the past decade and achieved good performance. Efforts have focused upon many other fields but properties of features have not been well investigated. In most cases, a group of features is selected in advance but important feature properties are not well used to feature selection. In this paper the performance of different features are compared, different combinations of features and a number of classification methods applied on the image annotation task, which gives insight into the features properties are also discussed
