Robots based on vision guidance are very important to the future of vehicle navigation. They have the ability to navigate through a predetermined track and avoid obstacles. They operate remotely with a central computer tracking and guiding them. This allows for communication between robots. This can be used to implement traffic based navigation. Where routes can be recalculated depending on traffic flow. Use of server based system paves the way to collaborate among different robots.

We study the denoising performance of several graph wavelet filter banks andimage modeling with graph to enhance understanding of the relationship between graph signals and underlying structure. We design a new metric for measuring graph structure similarity (GSSIM) to evaluate those methods. GSSIM is positively related to PSNR as an index of corrupted signal with an additive Gaussian noise in the references and it is aware of graph structure. Subgraph-Based filter banks are superior to others in graph signal denoising. We introduce the idea of group-based approaches by removing edges between different groups, a set of communities with similar average. It can improve the signal to noise ratio substantially and reduce the high frequency loss. We demonstrate GSSIM is promise through intuitive examples. Group-based analysis improves the denoising effect of all the methods studied.

In this paper, we will propose a method is to establishing 3D images and tracking objects in a plane space. The system in this paper will use automated. At first, grabbing dynamic environment images that from two CCDs, digitalized them by the image-grabber and then using digital imageprocessing techniques to become 3D environment images. Next step is to do objects recognition and locate them respectively. This action can achieve the function of object tracking. At last, the result of both simulations and practical experiments demonstrate the method that proposed in this paper is feasible.

One significant method of expressing the opinion of the users of social network is expressing true feelings or emotions through chats and comments for images, status or videos that has been uploaded to social network. This will increases the effectiveness of the communication among users since they have no face-to-face interaction. Text processing techniques are used to identify emotion which expressed through text. The research proposes an approach to get overall emotion from comment text towards an image, which uploaded to social network. The new methodology was developed as an enhanced extension of the previous works and using appropriate improvement and extension to them with Latent Semantic Analysis (LSA) because previous researches have proven that LSA is a light weight approach. And it is believed that, online emotion predicting systems must be light weight. The research achieved more efficiency than previous works due to light weight of the methodology, also introduced a prototype of GUI. Also the topic is open for future enhancement.

Aiming at the problem of Autofocus window selection in imaging system, a new algorithm based on visual saliency for Autofocus window selection is proposed, which provides a new solution. A re-designed Itti model is used to predict the salient region in the visual scene. By choosing the local maxima in the saliency map to be the seed, the most salient region can be obtained by growing around it and a minimum enclosing rectangle can be found as the focus window. In this paper, the focus window selection based on visual saliency can efficiently capture the visual salient region and the position of general target well, highlight potential focus targets and improves the accuracy of focusing. Compared with the common focusing window selection algorithm, the method proposed in this paper can improve the focusing performance of the imaging system and has wider applicability in the general scene.

Early diagnosis of breast cancer can improve the survival rate by detecting cancer at initial stage. In this paper, an efficient computer-based mammogram retrieval system is proposed, which helps in early diagnosis of breast cancer by comparing the current case with past cases. The proposed steps include cropping of mammograms, feature extraction using local binary pattern (LBP) and k-mean clustering. Using LBP, k-mean generates the clusters based on the visual similarity of mammograms. Further, query image features are matched with all cluster representatives to find the closest cluster. Finally, images are retrieved from this closest cluster using Euclidean distance similarity measure. So, at the searching time the query image is searched only in small subset depending upon cluster size and is not compared with all the images in the database, reflects a superior response time with good retrieval performances. Experiments on benchmark mammography image analysis society (MIAS) database confirm the effectiveness of this work.

Ubiquitous use of microscope in the field of medical diagnosis influences the development of automated systems. The inbuilt noise, illumination and contrast variations make microscopic imageprocessing an emerging field of computervision applications. This paper presents a novel and fast thresholding technique for microscopic data. To represent the inherent image vagueness, we use a fast processing fuzzy membership value generation technique using restricted equivalence function (REF). Then, a fuzzy entropy value is used to measure the total fuzziness present in the object and the background of the image. Finally, to search the optimal threshold value we use the well popular Bat algorithm. We have also implemented a multilevel thresholding technique for processing some complex fluorescence microscopy images. Experimental results on microscopic data and also on normal images show the superiority of the proposed thresholding technique. Experimental results on microscopic data and also on normal images show the superiority of the proposed thresholding technique. Proposed method is superior than other state-of-the-art methods not only in processing time but also in quantitative results.
