Website button has become one of the most important elements for users to communicate with website, so website designer pay more and more attention to the feeling towards interaction between human and machine, this research will explore the feelings of users material design button brings to human so as to learn about (1) elements why material design button attracts people (2) the usage feeling of...
As technology improving, technological equipment can now be used to interact during entertainment activities. In this study, a semantic differential scale was used to investigate the feelings of viewers about combinations of shapes and colors, and refer it to produce interactive digital art work. Moreover, an electroencephalogram device was employed to measure the EEG signals of the viewers during...
As a kind of ancient and mysterious folk behavior art, Changle Story integrates performances, painting, history, astronomy, geography, literature, customs, and the spirit of the times. Usually, children less than ten years old wear traditional clothes, and stand on a hathpace to perform a variety of Chinese folk stories. The performance form is unique. Essentially, it is a spontaneous performance...
Digital image processing is used in various spheres of production, medicine, as well as for laboratory researches. Many technical and scientific problems are solved successfully. One of the such problem is percolation (impregnation) — the theory what describes the appearance of infinite connected structures consisting of elements. This theory is used in field of capillary-porous material, such as...
The image on a digital book cover gives potential buyers not only an impression of the book's contents but also serves as an aid when searching and browsing before and after buying the book. We have developed a method for revising book cover images to reflect readers' impressions. It uses a database of the correspondence between adjectives and colors as extracted from book reviews. This correspondence...
Automated fire flame detection in the surveillance system has drawn significant attention. This paper presents a novel fire flame detection algorithm using motion estimation and color information. The key idea is using irregular motion vectors of the fire flame. This paper presents a novel fire flame detection algorithm using motion estimation and color information. The proposed algorithm consists...
In an image fusion, misalignment errors are generated in the boundaries between objects and background. To solve this problem, this paper presents an image fusion method using the optimal mask that contains main objects. The proposed method consists of three steps: i) pre-processing and global warping to register a tele-view image to a wide-view image, ii) generating seam-based optimal mask to detect...
Visualization of flow features, such as vortices, aids in analyzing complex unsteady (turbulent) flows and thus facilitate human cognition of flow phenomena. Typical data of unsteady flows are vector fields of velocity in four spatiotemporal dimensions (4D). Often empirical data of unsteady flows suffer from unknown measurement errors (i.e., undesired vectors). The undesired vectors lead to clutter...
Dichromats (a human with red-green color blindness considered in this paper) cannot always perceive meaningful visual information due to their deficiencies in eye cells. Stroke information extraction from a color-blindness image (CBI) is presented in order to deliver direct and effective information to dichromats. A CBI is first transformed into the pattern-highlighted image by means of color component...
Many skin detection approaches have been proposed in the image analysis literature. Some are simple and static; the others are dynamic and rely on complex machine learning algorithms and training data. Generally the simple approaches are preferred. We hypothesize that the developers' choice for the simple approaches are due to the reasonable quality of results and ease of implementation, since the...
Color is a significant visual characteristic for both human vision and computer processing. Global color descriptors characterize an image by its color distribution or histogram, and discard information about object location as well as content of different colors. In this paper, we proposed a local color descriptor based on indexed matrix wavelet analysis and fuzzy decision support system (FDSS),...
Augmented reality (AR) is widely used in various applications of computer vision, such as marker-based AR and markerless-based AR. These AR techniques are used in various fields, including industry, education, and medicine. Using marker-based AR, employees can easily perform step-by-step maintenance and repairs, and they can register parts information for large plants. However, conventional marker-based...
Sensor fusion is an important part of modern cyber-physical systems that observe and analyse real-world environments. Time-of-Flight depth cameras provide high frame rate low-resolution depth data that can be efficiently used in many applications related to cyber-physical systems. In this paper, we address the critical issue of upsampling and enhancing the low-quality depth data using a calibrated...
Effect of frame size and color histogram bins on shot boundary detection performance in terms of precision and recall is experimentally analyzed in this paper. An HS histogram-based shot boundary detector is used for Korean soap operas with eight kinds of frame sizes an bins, respectively, applying various thresholds. The biggest image size and bins are more than one hundred higher than the smallest...
Outdoor visual surveillance systems have studied object tracking in non-overlapping multiple cameras. In this paper, we present a data association method for multi-object tracking in a non-overlapping camera network. Proposed method is based on similarity function which consists of a multi-camera topology obtained from local tracking results and matching results from person re-identification. Simulation...
This paper presents an iterative motion estimation and error evaluation method for efficient occlusion detection. From a pair of reference and target images, the proposed method detects occlusions using four steps: (i) pre-processing for robust motion estimation, (ii) detection of candidates for the occlusion, (iii) one-dimensional motion estimation, and (iv) motion evaluation and update in the target...
This paper presents the color reproduction method for dual camera system. The proposed method uses the input images acquired in different exposure conditions. The brightness of short-exposure image is restored using conventional haze removal-based low-light image enhancement method. Next, the color components of the brightness enhanced image are restored using the weight map, which is computed between...
Haze is mainly occurred by atmospheric phenomena. Recently, many researchers in haze removal algorithm area are using single image. At the single image, we can't use depth information. To estimate the thickness of haze without depth information is not easy. As a result, single image haze removal method includes halo effect. In this paper, we propose halo effect suppression for single image haze removal...
We proposed new entertainment system called "Light Crayon", projection system user can draw line on screen like using crayon. In this paper, we introduced visible light communication to this to enhance the expression and entertainment ability. As result, visible light communication succeed to transfer binary data at 12 bit/sec. We also made 2 game programs with new system.
This method achieves efficient random explorations of open and dynamic environments. It relies on two main assumptions: (1) moveable object are interesting, (2) focus on visually salient areas first, that are not specific to a particular scenario or experimental setup.
