Rare colored capsule (RCC) is the capsule which is mixed in the normal product but with different color. To detect this kind of capsules online, a method based on RGB color space and using HSV color difference formula is proposed in this paper. Considering HSV color space with more balanced color-difference perception, the original RGB formatted capsule image is transformed to HSV color space for...
In recent years, in a game or AR (virtual reality), various modes of expression using a computer are proposed. The new system developed with a computer, a projector, and a camera as one of such the modes of expressions. The system irradiates the light such as the laser pointers to the screen under projection. It is reflected in the screen image data under projection by taking the irradiation locus...
Karyote segmentation, a significant procedure to computer aided leukemia diagnosis, constitutes a difficult problem due to the morphological complexity, categorical diversity and distributional density of bone marrow cells. Most of the current techniques are based on the internal consistency of the karyote's intensities with little or none considerations on color or texture properties. However, neither...
Inpainting is the process of reconstructing damaged parts of an image in a visually plausible way. Recently, digital image inpainting has been an active field of research in the area of image processing. Meanwhile, exemplar-based methods have had a major contribution in developing this field of research. The main idea in these methods is based on copy-and-paste texture synthesis. The time-complexity...
Proper technology transfer based on scientific data is inevitable for farmers to promote sustainable agriculture which is a common target of modern food production. In under-developing countries, illiteracy of farmers is one of the major reasons for them to receive sufficient information and knowledge for such sustainable food production. In this study, we conducted a trial to examine effectiveness...
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...
The quality of the repaired image will be directly influenced by the error accumulation of initial repaired for the target block in the exemplar-based algorithm. According to analysis of the pixel's surrounding image features, a new algorithm which joint structure characteristics and color differences is proposed in this paper. This algorithm considers the color differences and structure characteristics...
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...
The elementary technology for video retrieval technique in computing is very sensitive to the user's query not to the contents of video. Every user has perspective to the video in the world of videos. So to identify this is difficult using text based video retrieval as this retrieval is based on text as processing input for video retrieval. The better approach for this video retrieval is content based...
This paper proposes a pseudo-color fusion algorithm of night vision image based on environment-adaptive color transfer, which is proposed on the basis of histogram specification. This method can effectively transfer the environmental image colors to fused image, extraordinary save the image processing time, and guarantee the real-time nature of fusion system. The algorithm simulation is also studied...
Organisms use the process of selective attention to optimally allocate their computational resources to interesting subsets of a visual scene - ensuring that they can parse the scene in realtime. Many models of attention assume that basic image features (e.g. intensity, color and orientation) behave as attractors for attention. Gestalt psychologists, however, argue that humans perceive the whole before...
CAPTCHA (also known as verification code) is mainly used to guarantee the login security of the interactive websites. At present, the most popular verification code is image CAPTCHA which can distinguish the human user from the computer by identifying characters in the image. Although the image CAPTCHA is safe at beginning, great deals of CAPTCHAs have been cracked by the computers along with the...
Background subtraction method is a tracking method only based on motion information. It cannot make a distinction between the foreground objects detected. The feature-based tracking methods need to select the appropriate prediction and search algorithm. But the algorithm complexity and amount of computation is large for the multi-target tracking. Therefore, this paper presents the method based on...
Parallel coordinates is a very important visualization method, but the dimensions it can express are limited by the length or width of the screen. In this paper, we present the polar parallel coordinates method. First, we define the polar parallel coordinates as the coordinate whose axes exist between the same degree and show the expression of the axis. We give the algorithms for the polar parallel...
The purpose of this paper is to provide reference for the design of more practical and efficient non-distributed flight reference(NDFR) symbology of helmet-mounted display(HMD) by comparing four kinds of attitude symbologys (include climb-dive angle and roll). The flight references were NDFR, NDFR-R (NDFR plus zero-degree Climb-Dive Angle CDA reference), NDFR-M (mini-arc NDFR) and ANDFR(Advanced NDFR)...
Parallel coordinates, an important tool for multidimensional data visualization. The property axes of the traditional parallel coordinates are of equal length, which are restricted in many ways. This paper presents a parameterized parallel coordinates method by adjusting the parameters get by function to control the length of different axis. When the axial length get by the polar equation, parallel...
Data warehouse (DW) testing is a very critical stage in the DW development because decisions are made based on the information resulting from the DW. So, testing the quality of the resulting information will support the trustworthiness of the DW system. A number of approaches were made to describe how the testing process should take place in the DW environment. In this paper we will present briefly...
The speed of calculating, tracking and filling the isolines has a direct impact on the performance of user interaction. In this paper, we begin with the serial algorithm of visualization and implement its parallel algorithm. First, we divide the Delaunay grids generated from the PEBI grids into several regions. Calculation, tracking of isolines and calculation of saturation are implemented in each...
The image segmentation is an important using in the computer image processing. This paper proposed a new method: the color components' exchanging on the different color spaces. Based the method and combine with other traditional image segmentation methods, try to use in the image segmentation, and get some results.
The importance of intercommunication and communication is increasing, as the world is moving toward globalization. Apple Inc. (Apple), a global multinational enterprise, is dedicated to creating products that enable people of many nationalities and races to realize unlimited human-machine interaction. With simple and clear UIs, iPhones are welcomed around the world. These UIs share a kind of general...
