This paper presents a low cost eye based Human Computer Interface (HCI) developed for amputees and paralyzed persons. The system is a computer interface that provides the functionality of an input device like mouse based on eye actions such as eye blink, eye-gaze and gaze control. For initialization, the subject just holds his/her head still for a few seconds: using involuntary blinks that would naturally...
Recently, investigating boundary prior to aid other low-level image cues, have gained great attention in salient object detection. Although the salient regions are mostly located in the image center, the inverse might not necessarily be true. In addition, such kind of center-bias assumption is very simple and fragile, especially when salient regions often touch the image boundary or the images are...
This paper objective is to analyze LBP and CM for the comparative analysis in the field of content based image retrieval (CBIR). In this paper LBP and CM methods are used for the efficient retrieval of the images from the Wang database. All the 10 classes are used for the results comparison. LBP is used for better thresholding and CM is used with color dominant features for the efficient retrieval...
How can we use information visualization to support retrospective, exploratory analysis of collections of histories for patients admitted to acute care? This paper describes a novel design for visual cohort identification and exploration. We have developed a tool that integrates multiple, heterogeneous clinical data sources and allows alignment, querying and abstraction in a common workbench.
With the rising popularity of mobile devices, recent years have witnessed a growing interest in document image retrieval (DIR). In conventional Bag-of-Visual-Words (BoVW) based document image retrieval method, only SIFT or SURF feature is used to locate feature points and produce a codebook, which has a low discriminative power. Though several multiple feature based BoVW methods are proposed, these...
Saliency detection is detecting the more attracted regions in an image. Like a loud noise in a quite environment. Saliency is the contrastic difference between the visually attracted items and their neighbourhood. Detecting such attracted areas in the image is termed to be saliency detection. Salient region detection can be broadly classified into contrast based method, learning based, rarity based...
The DTI's current virtual shooting range detect only one shooting gun. If there are many gun shots upon the same training scenario, the system cannot know what gun shoot belongs to what gun. The goal of this research project is to prove the concept of developing an algorithm to classify gun identification. The gun identification plays an important role in multiple weapon shootings of the virtual shooting...
Image colorization is the technology used to add colors to a grayscale image by computers. A novel image colorization method based on local and global consistency is proposed, which uses an oversegmentation-based graph model and a modified energy function to take advantage of the local and global information of each pixel. An oversegmentation-based graph model is used to approximate each pixel by...
Most image cluster algorithms group images based on the content, that can be described with some low-level image features or geometry features. In this paper, we proposed novel grouping criteria for image cluster from a aesthetic perspective. By studying the skills and techniques of professional photographers, we introduce several image features that can describe the styles of photographs. And we...
Analyzing how software engineers use the Integrated Development Environment (IDE) is essential to better understanding how engineers carry out their daily tasks. SPOTTER is a code search engine for the Pharo programming language. Since its inception, SPOTTER has been rapidly and broadly adopted within the Pharo community. However, little is known about how practitioners employ SPOTTER to search and...
The motivation behind this work is to explore and pursue benefits of Cognitive Informative and Artificial Intelligence. Computer based Image Analysis and Machine Vision are based on Image Processing Algorithms. Choosing the best concept to comprehend a meaning in natural language generation is one of the tough tasks. A vision system while navigating in an environment should be able to recognize what...
Dynamic horizontal image translation (HIT) denotes the act of slowly shifting stereo views horizontally in opposite directions in order to ensure that points of visual attention are located near the display plane. Thereby, visual discomfort is reduced. This technique is widespread, however, little is actually known about its visual perception by a human observer. Therefore, two experiments have been...
The research of network image's classification is not only the basic research on network image's creation and application, but also the important content for image information's resource management. This paper did classification research into network image, according to network image's category of generation, format, language form and retrieval, and put forward practical methods and outlook toward...
The 2D-to-3D conversion technique plays an important role in the development and promotion of three-dimensional television (3DTV), because it can easily provide 3D program contents. This paper focuses on the real-time autmatic 3D conversion method. Depth map is made by the efficient combination of luminance, color, visual saliency, caption localization and final surface modeling. Then the 2D image...
A new approach to teaching technical disciplines in training of Radio Engineers is proposed. The approach is based on the method of non-linear note-taking using mind maps. This method allows students to analyze and process the studied material quickly and with high quality by engaging both the left and right hemispheres of the brain in the work. The effectiveness of this approach is shown and its...
Illustrators who have some drawing experience can sometimes draw an ideal stroke repeatedly. However, they cannot always reproduce an ideal stroke that they have drawn, because they do not understand how they moved their own hands while drawing it. Therefore we proposed a new drawing learning support system based on present- ing the ideal stroke motion of the learners (past brilliant learner- self...
Visual strain will be caused by PC operations for a long time a day, which might fail health of human eyes if it continues a week or more. Any action to check it by oneself needs to be done every time PC operations are continued for a multiple of hours. We propose a visual fatigue checker to simply test the fatigue of human eyes and to help us to resume visual health from the fatigue, if any, with...
Computer technology injects new vitality to the field of graphics design; computer graphics technology is adaptive to the era of rapid development of economic globalization and three-dimensional business competition. With the development of economy, computer graphics technology develops rapidly. Now, the development of the computer graphics technology is mainly divided into two-dimension technology...
We present stego-marbling-texture, a new and unique texture design method which allows users to deliver personalized messages with beautiful marbling textures. Our approach is inspired by the success of the recent work on modeling traditional marbling operations as mathematical functions. The encrypter transforms an input image or a text message into an intricate marbling pattern using marbling operations...
This paper presents a questionnaire based intercultural study carried out to identify the differences observed in people when individually interact with the CM-ED Concept Map Editor. Each participant interpreted and localised to his/her own culture a Concept Map (CM) about a sensitive topic. The aim of the study was to identify what visible elements of a CM are meaningful from a cultural perspective...
