Classification of Images for Automatic Textual Annotation: A Review of Techniques

Juzlinda Ghazali, Shahrul Azman Noah and Lailatulqadri Zakaria
Annotating images with text is one of the approaches to represent semantic meaning of images. Automatic classification of images into various semantic categories is one of the many steps required to perform the automatic textual annotation as exhibited in many research in this area. However, little or none researchers in this area do provide detail evaluation for selecting the best or suitable technique for performing image classification. The majority of the researchers mainly select any of the available machine learning technique and apply it as part of their proposed approaches and algorithms. In this study, six techniques were reviewed, which are SVM, Multilayer Perceptron, Bagging, DECORATE, C4.5 Decision Tree and Random Forest using 429 Flickr images relating to Malaysian tourism. Image feature extraction using 3D Colour Histogram with 64 and 216 bins were done. The results show that DECORATE has the best accuracy.
