We propose new efficient visual features called Profile Entropy Features (PEF), giving information on the structure of the image content, and defined as the entropy of the distribution of a projection of the pixels. We analyse two simple projection operators (arithmetic or harmonic mean), and two orientations (horizontal and vertical). PEF are fast to compute (10 images per sec. on a PentiumIV) and...
Semantic-based image retrieval bridges the gap between visual features and human understanding of image in the field of image retrieval. Image annotation is one important technology of image retrieval based on the semantic. This paper proposed one method to realize semi-automatic image annotation with the tool Support Vector Machine (SVM). The image collection was divided into two parts, one for manual...
