The username/password combination is still the most widely used method albeit various user authentication techniques have been introduced. Numerous studies have been conducted to investigate the scheme and it could be summarized that despite it weaknesses, it is the most favourable scheme. Thus, to reduce the weakness, authenticating users with image or pictures (i.e. graphical password) is proposed...
In the image in painting process, the data term of the Criminisi algorithm depends on the shape of the manually selected target region and the confidence drops to zero rapidly, resulting in in painting sequence deviation which finally influence the in paint effect. Then we introduce the entropy to improve the data term, in this way another priority function will be defined. Experiments confirm that...
In recent years, content-based image retrieval achieved continuous development, but in the previous studies, only the relevance is cared in retrieval system, so many duplicate or near duplicate documents retrieved in response to a query and cannot satisfy the users. To solve this problem, we propose the Content-based Diversifying Plant Image Retrieval in this paper. In order to make the retrieval...
In this paper, we present a novel and original framework for computing Local Binary Pattern (LBP)-like patterns on a triangular mesh manifold. This framework, dubbed mesh-LBP can be adapted to all the LBP variants employed in 2D image analysis. As such, it allows extending the related techniques to mesh surfaces. First, we describe the foundations, the construction and the features of the mesh-LBP...
User experience design is crucial to achieve a successful intelligent product design. By taking the user experience design of a xylophone playing robot as an example, this paper attempts to identify the prominent attributes in the user experience design of intelligent products, and to find the general norms guiding the design. Both the pragmatic and the hedonic aspects have been investigated via questionnaires...
In medical field, patterns over time-varied data streams usually imply high domain value. The variations of patterns can often be very complex and hard to evaluate. Traditional methods usually take each pattern as a whole to analyze data stream variations or only focus on one type of variation; however, few works have achieved a widely applicable resolution. This paper considers the feature of sub...
Development of automatic multiple intracellular-objects tracking methods is one of the significant challenges in Bioimage-Informatics. The challenge becomes more difficult in case the tracking targets have the same shape and appearance. In order to obtain stable results under that condition, we propose a tracking method based on global optimization. Particularly, we first detect tracking targets by...
It is a very challenging problem to make robot vision autonomously identify and recognize objects in the real world, and the recent research in this field has been moving forward mostly through designing smart shape descriptors for providing better similarity measure. In this paper, we propose a novel shape descriptor called hierarchical representation to describe the object shape efficiently and...
In this paper we study the statistical properties of urban street networks. We show that urban and non-urban street networks can be differentiated through their statistical properties, suggesting at a transition between two phases. We introduce a definition of city boundaries based on the percolation properties of the network in the street intersection density space, through the concept of city condensation...
Autism is a disorder of neural development characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behavior. Visual supports can alleviate these challenges by juxtaposing communication with visual cues. In this paper, a "Rehabilitation Training System (RTS)" for children with autism is developed. The "RTS"...
People use both their speech and their body when they communicate face to face, thus human communication is multimodal. The development of multimodal coginfocom systems requires models of the relation between the various modalities, but many studies have shown that multimodal behaviours depend on numerous factors comprising the culture, the setting and the communicative situation. Thus, annotated...
The conditions on the coefficient vectors of parametric polynomial minimal surface of arbitrary degree with isothermal paprameter is investigated. From the conditions, polynomial minimal surface of arbitrary degree with shape parameters and elegant properties can be constructed for shape design.
This paper presents an efficient and physics-plausible deformation algorithm. A simplification is first conducted on the original mesh, then the deformation of the simplified mesh is passed to the original mesh to obtain an initial result. Then a set of optimal rigid transformations are computed to preserve the shape features and control the surface stiffness. The experiments show that our algorithm...
This paper proposes a framework for matting identification photos automatically. We firstly adopt image processing operations such as skin detection, k-means clustering, Grab cut segmentation and canny operator to generate a trimap with three regions, i.e., background, foreground and unknown regions. Then, we improve the Bayesian matting by introducing an alpha regularization term. Experiments demonstrate...
In this paper a design and implementation method of smart energy hub is presented. This energy hub can incorporate diversified renewable energy, automated and intelligent management. The design of it deeply considered on the use of renewable energy and the reliability of power supply for critical load. It can be used as a basic unit of smart distribution grid, and it designs to operate in both grid...
In this paper we present novel algorithm for the cursive style Korean handwriting synthesis method based on the shape analysis with minimized input data. Hangul (Korean Character) has the different characteristics in structure, that is, character consists of consonants and vowels like English and also it is a combination character like Chinese character. This research aims at using minimal input character...
Graph cut based interactive segmentation is useful to extract objects from images. Color and gradient constraints are two terms appearing in most of energy functions of related methods. In order to balance the two constraints, state-of-theart methods adopt a pre-given fixed weight. However, different images and even different parts in a single image have different demands for proportion of the two...
‘Squash & Stretch’ is a fundamental technique in traditional animation, in which the shape of a character or object is intentionally distorted in order to accentuate its movement. Unfortunately the fluid deformation required by the squash & stretch technique is difficult to achieve using current tools, because the development of computer graphics algorithms has been largely driven by the goal...
The physiological consequences of Alzheimer's disease (AD) concern the development of amyloid plaques and neurofibrillary tangles. Development of amyloid plaques in the brain is caused by Amyloid Beta that forms part of an amyloid precursor protein. In a normal brain, these protein fragments are broken down and eliminated but with AD, these fragments accumulate to form hard insoluble plaques. Our...
This paper is based on the theory of particle system, researching the basic model and principle of setting off fireworks, based on the basis original model, we add some new constraints, such as wind-force, temperature, buoyancy force, at last the model of fireworks is realized. The simulation of fireworks is distinctly and real-time at last.
