Leopard Image Retrieval using Region of Interest and Texture Feature
In content based image retrieval system, texture based natural image retrieval can not extract texture feature efficiently and accurately, because the nature image is very complex and most of method extract feature use the whole nature image. In this paper, a new method is proposed for leopard texture image retrieval. Usually, the habitat of leopard is grass or tree, there is large difference between leopard image background and foreground, so it is easy to separate the leopard region from background using Canny edge detection, and then extract region of interest of foreground. The similarity of two images will be determined by the similarities between pairs of region of interest. The experimental results on the leopard texture image database demonstrate that the proposed method is encouraging with an average successful retrieval rate of 95.66%

ROI Based Natural Image Retrieval Using Color and Texture Feature
Region of interest(ROI) plays an important role in image analysis. In this paper, an efficient approach for content based image retrieval combining both color and texture features using three ROIs is proposed. Firstly, segment image to three parts using K-means algorithm. Secondly, select three ROIs from the three parts and then extract color features and texture features of ROIs. The similarity of two images will be determined by the similarities between pairs of ROIs. The experimental results demonstrate that the proposed method is encouraging with a successful retrieval rate.

A Novel Approach Using Edge Detection Information for Texture Based Image Retrieval
Most texture-based image retrieval system just consider an original image of coarseness, contrast and roughness, actually there are many texture information in the edge image. In this paper, a method combining both edge information and gray level co-occurrence matrix properties is proposed to improve the retrieval performance. The proposed method gives encouraging results when comparing its retrieval performance to that of the Yao's method, in the same image database.

Topic-Level Random Walk through Probabilistic Model
In this paper, we study the problem of topic-level random walk, which concerns the random walk at the topic level. Previously, several related works such as topic sensitive page rank have been conducted. However, topics in these methods were predefined, which makes the methods inapplicable to different domains. In this paper, we propose a four-step approach for topic-level random walk. We employ a probabilistic topic model to automatically extract topics from documents. Then we perform the random walk at the topic level. We also propose an approach to model topics of the query and then combine the random walk ranking score with the relevance score based on the modeling results. Experimental results on a real-world data set show that our proposed approach can significantly outperform the baseline methods of using language model and that of using traditional PageRank.

A Color Indexing Scheme Using Two-level Clustering Processing for Effective and Efficient Image Retrieval
[Abstract]: In this paper, we present a clustering-based color indexing scheme for effective amd efficient image retrieval, which is essentially an exploration on the application of clustering technique to image retrieval. In our approach, the color features are clustered automatically using a color clustering algorithm twice (called two-level clustering processing) and two color feature summarizations are obtained, e.g. Local Color Centriods (LCCs) and Global Color Centroids (GCCs). Based upon LCCs and GCCs, a three-level R-tree is bulit for indexing database images and performing effecitve and efficient image retrieval. The experiments show that this indexing scheme is effective and efficient in performing image retrieval.

On the Integration Frame of Collaborative Innovation Support System for Telecom Operators
As the industry value-chain getting complicated, collaborative innovation becomes an important competitive factor for telecom operators. However, collaborative innovation means more participators and greater uncertainty in the innovation procedure. As a result, collaborative innovations usually cost more in time and money, which could make the innovations lose or bring serious problems even when new services have been launched into the market. In this paper, the integration frame of collaborate innovation support system (CISS) is put forward. Firstly, the participants and resource flows in the collaborative innovation in telecom industry are analyzed. Based on that, the requirements and functions of CISS are summarized. The system should help to connect the necessary resources for innovations and implement process management in an efficient way. Secondly, the framework of CISS is designed, defining functional construction and information flows. Then the key technologies supporting CISS are illustrated. Functionally, the CISS should be a part of BSS/OSS (Business/Operating Support System), and the relationship between CISS and BSS/OSS is explained. Finally, the organizational and managerial supports for the system are discussed.

Multimodal Registration using the Discrete Wavelet Frame Transform
Image registration is a critical step in medical image analysis. In this paper, a novel image registration method based on the discrete wavelet frame transform (DWFT) and the sum of absolute distance (SAD) method is proposed. First, the multimodal images are decomposed by DWFT, which is shift-invariant compared to traditional dyadic wavelet transforms. Then the energy maps are computed from the details sub-band images. Finally, genetic algorithm (GA) is adopted to obtain the minimum SAD between the two energy maps. The proposed method is tested on 50 pairs of two-dimensional T1-weighted and T2-weighted modal images. Experimental results demonstrated that the proposed method can achieve high accuracy in the rigid transformation case
