Graphene Quantum Dots (GQD) is used for detecting lard substance. It is discovered that the fluorescence for a GQD with a size approximately 5nm in size will have a peak at 675nm. Introducing lard substance to the GQD will induce a broad fluorescence spectrum at the range of 415 till 715nm. Higher fluorescence is observed from 760nm till 860nm showing the dynamics fluorescence changes when lard is...
In this paper we present an overview of several techniques that are used when the layout pitch and feature size become significantly smaller than the minimum resolution of the lithographic process. We consider several multi-patterning (MP) techniques, in which a single layer is decomposed into two or more masks and printed in multiple stages. We also introduce the direct self-assembly (DSA) technology,...
Our target is development of a view synthesis system that includes the entire process from capturing of multi-view videos to synthesize virtual view in real-time. Depth estimation of the target scene is indispensable for view synthesis from multi-view videos. In this paper, we improved the depth estimation method we had developed in a previous work, where an active illumination technique was combined...
How can we design intelligent play environments for open-ended play that support richness in play? Rich play can be described as ongoing play that changes over time in character, form and nature. This paper elaborates on our initial insights on how rules and goals develop from interaction opportunities of the system, based on two pilot studies with an interactive play environment for open-ended play...
Processing surfaces with data coming from an automatic acquisition technique always generates the problem of unorganized 3D point sets or presence of geometric deficiencies (i.e. in some regions of the surface, the obtained data points are sparse or without containing any points). It leads to what we call "holes", and a mandatory surface reconstruction process. Applying the process to the...
In this paper, we propose a novel online visual tracking algorithm using ensemble color feature. Visual tracking has long been one of the most important topics in computer vision. In recent years, significant progress has been achieved by the state-of-the-art tracking algorithms. However, some challenging problems still remain unsolved. One general problem is that it is difficult for a tracking algorithm...
Diversity of users has become recent design concerns, and children are one of those user groups. Organization of contents is one of research areas in designing for children. Research suggests differences in abilities between adults and children; for instance, attention, logic and memory skills, and linguistic abilities. This is related to the way children navigate and access information. Efficient...
This paper presents a new level set tracking method for the tracking of non-rigid objects in videos. The main idea is to introduce a new probabilistic model to classify the background and object more robustly, which is then encoded as a new term for the energy function for solving the level set problem. Also, we propose to use bounding box of the contour as a shape prior, which simplifies the contour...
The aim of this work is to make a visibility test, which answers how the environment and form influence colour perception. A test program in C# was developed, where the observer can make experiments with different settings. The variable background colour and the variable form colour help to test how these factors influence colour perception. In a second experiment a Tobii X60 eye tracker was used...
Traffic signs detection is a key part of traffic signs recognition system. We propose an improved approach for traffic signs detection based on significant color extraction and geometric features. Firstly, we use a median filter to remove the noise. Secondly, we calculate the quadratic weighting difference of R, G and B in RGB color space to extract the significant color of the traffic sign. Thirdly,...
Color segmentation is a preliminary step in many application computer vision systems today, as the detection of human movement, recognition of road traffic signs and video intelligent. Detection stage performance is therefore closely linked to the results obtained from the color segmentation. Detection and recognition automatic road traffic signs are applied in the color spaces RGB, HSV, and HSI....
An objective of an autonomous sociable robot is to meet the needs and preferences of a human user. However, this can sometimes be at the expense of the robot's own ability to understand social signals produced by the user. In particular, human preferences of distance (proxemics) to the robot can have significant impact on the performance rates of its automated speech and gesture recognition systems...
Visual recognition in multi-robot systems is afflicted with a peculiar problem that observations made from different viewpoints bring different perspectives. Due to the lack of a discriminable representation between a target and its surroundings in different viewpoints, realizing cognitive sharing of the object among the robots in an unconstructed environment is a challenging issue. In this paper,...
People are highly efficient in recognizing faces. However, it is almost impossible for them to cope with huge datasets of facial images without any computational support. On the other hand, the way people describe the facial features using quite commonly encountered descriptors such as “long nose”, “small eyes” and also allude to their feelings according to a specific person like “seems to be nice”,...
A key mechanism of privacy-aware smart video surveillance is anonymization of video data. We conducted a user study with a response of 103 participants in order to investigate which pixel operations are suitable for protecting persons' identities while, at the same time, allowing a human operator to recognize persons' activities i.e., preserving the utility of the video data. Regarding the activities...
Fire detection is one of the most interesting issues for surveillance. The existing approaches for the fire detection suffer from a high false positive ratio. To solve the problems, we present a patch-based fire detection algorithm with online outlier learning. In the proposed algorithm, the candidates of fire are obtained in the form of patch, while the classical candidates have been based on pixels...
Facial shape cloning (FSC) is a task aiming to simulate the plastic surgery result of reshaping a user's face to bear analogy to a model's facial appearance. Facial cosmetic reproducing (FMR) is another task intending to emulate the transfer of the cosmetic effects on a model face to the user's face. This paper presents a method which can perform both the FSC and the FMR. This proposed method features...
Wings of airplanes, ornithopters and micro-aerial vehicles were inspired by the wings of birds and insects. A flying snake found in South and South-East Asia converts its entire body into a morphing wing which aids it to glide very efficiently. The aerodynamics of this species of snake is not well understood. Two dimensional computational and experimental studies of the snake's rather unusual cross-section...
The goal of this work is to recover road networks from aerial images. This problem is extremely challenging because roads not only exhibit a highly varying appearance but also are usually occluded by nearby objects. Most importantly, roads are complex structures as they form connected networks of segments with slowly changing width and curvature. As an effective tool for their extraction, we propose...
We describe an artistic method used for the psychological analysis of group dynamics. The design of the artistic system, which mediates group dynamics, emerges from our studies of modular Playware and remixing Playware. Inspired from remixing modular Playware, where users remix samples in the form of physical and functional modules, we created an artistic instantiation of such a concept with the Parallel...
