In this paper we investigated how merging of MPEG-7 visual descriptors can improve accuracy of image classification systems. Combination of MPEG-7 Colour Layout Descriptor (CLD) and Edge Histogram Descriptor (EHD) was used to extract features for input into multiclass Support Vector Machine (SVM) classifier. SVM classifier was trained and evaluated on a standard test database of 1000 images classified...
The focus of this paper is on automatic annotation for semantic image retrieval. This work is aimed at identifying visual descriptors that are most relevant, effective and suitable for semantic annotation tasks. We propose an image annotation system based on support vector machines and a combination of descriptors that includes a gradient direction histogram and several MPEG-7 visual descriptors....
