image saliency analysis, object detection and tracking, and multimedia copy detection and search. The first part contains two papers about image classification. The first paper, "A New Discriminative Coding Method for Image Classification", introduces a locality discriminative coding method. In the method, a feature point is converted into a code vector using local feature-to-class distance instead of k-means quantization. This approach is demonstrated to outperform conventional feature coding

In the second paper, "Large-margin Multiview Gaussian Process", Xu et al. introduce a large-margin Gaussian process approach for discovering discriminative latent subspace shared by multiple features. The method incorporates the Gaussian process with the large-margin principle, and thus the learned latent subspace for highdimensional multiple features is more discriminative and effective for a subsequent image classification task. The second part contains two papers about visual saliency analysis. The first paper, "Image Aesthetics Enhancement Using Composition Based Saliency Detection", introduces a novel saliency detection method which utilizes the knowledge of photographic composition as priors to improve saliency detection results. In addition, an online parameter selection method is employed for achieving better saliency segmentation results. In the second paper, "Camouflage Texture Evaluation Using Saliency Map", Xue et al. introduce a histogram-based contrast method to measure saliency, in which the saliency map is computed simply by color and texture separation from a whole image. The saliency map is then used in camouflage effect evaluation. In the third part of the special issue, we have two papers focusing on object detection and tracking. The paper "Efficient Human Detection in Crowded Environment" introduces an efficient method for detecting humans in crowded International Conference on Internet Multimedia Computing and Services (ICIMCS) is an annual conference series sponsored by ACM SIGMM China Chapter, focused on the latest Internet multimedia management and processing multimedia technologies and applications. ICIMCS 2013 was held in Huangshan, China, in July 2013. The conference has attracted over 100 participants, including researchers from academia and industries across more than ten countries/regions, for sharing their recent works. In total there are 94 regular submissions which cover widely in multimedia content analysis, multimedia signal processing and communications, and multimedia applications and services. There are 69 papers accepted after a rigorous review process. With regard to this special issue, we have invited the authors of ten papers that have highest review scores from the conference to submit an extended version of their work. After at least two rounds of rigorous reviews, nine of them are accepted. These papers cover key issues in multimedia computing, including modeling for visual classification,
