Emotions influence our perceptions and decisions and are often felt more strongly in situations related to healthcare. Therefore, it is important to understand how both providers and patients express their emotions in face-to-face scenarios. An ontology is a way to represent domain concepts and the relationships between them in a polyarchical manner. We have created an ontological model called the...
The landscape plant as spatial element used in the construction of parametric configuration system is a fresh concept and technical innovation. This System is aimed to help designers without botany knowledge to finish some simple plants arrangements. Through the construction of plant parametric configuration system and some typical trees and shrubs parametric database, we use examples to illustrate...
Different types of traffic signs has different colors and shapes located in uncontrolled traffic environments. The detection of different types of traffic signs is a difficult problem in pattern recognition and computer vision. In our study, a region of interest (ROI) extraction method is proposed to extract ROI using color contrast in local regions. We utilize the high contrast in local regions to...
In order to improve the elïïciency of apple's grading and ensure the scientilïcity and objectivity of grading, this paper presents a three-stage grading system, namely weighing grading, color grading and shape grading. Hardware design uses high-performance S3C2440 embedded controller, DSP controller, single-chip micro-processor controller, pressure load sensor, color recognition sensor, graphic recognition...
This paper proposes a systematic framework for applying the Physics of Notations (PoN), a theory for the design of cognitively effective visual notations. The PoN consists of nine principles, but not all principles lend themselves equally to a clear and unambiguous operationalization. As a result, many visual notations designed according to the PoN apply it in different ways. The proposed framework...
This paper presents a serious game designed for children suffering from profound intellectual and multiple disabilities (PIMD) also know as multihandicap, for their evaluation and cognitive training. The specificities of these children must be taken into account for the choice of both the game feedbacks and interfaces.
Usually the static or dynamic characteristics of the flame are extracted for flame detection. But the relationship between the various features of flame could not be distinguished by the human eye. the Gradient Boost Decision Tree (GBDT) is thus proposed to combine and optimize the flame shape and texture features, so as to mine the relationship of flame features. Then the more discriminant new flame...
This paper proposes a design support system to make a room design with freshness and originality impression suitable for user's requirement interior styles. The proposed system supports to create the design plan through two steps: Creation process and Selection process. In the creation process, the system generates various design ideas by using several style furniture. In the selection process, the...
Computer Aided Diagnostic (CAD) tools for differentiating benign and malignant lesions are primarily of great importance. Most of the CAD tools employ a large and complex feature set. In this paper, a CAD system for classifying benign and malignant lesions using optimal feature set is proposed. The optimal feature set included the prominent color, shape and texture features. The feature set used is...
In this paper, we propose Local Adaptive Hybrid Pattern (LAHP) to use intrinsic properties, both edge and color, of each pixel adaptively (inspired from LHP based methods) while using a single feature representation (inspired from LOBSTER). The proposed LAHP encodes edge and color information, and an adaptive factor based on gradient magnitude together as a single feature. We introduce a way to calculate...
Recent background subtraction methods use fusion of multiple features to achieve consistent performance in non-stationary environment. During the segmentation, most of these methods apply logical operators (AND, or OR) to the results of each observed feature. Using logical operators has two critical problems, e.g. i) AND operator may reduce true-positives, and ii) OR operator may increase false-positive...
In topology representations such as maps, carbon nanotubes, and cellular networks, neighboring cells are assigned different exclusive colors to represent different characteristics. In the previous research, based on the fourcolor theorem, an algorithm that can allocate exclusive channels among neighbors using only four channels in a polygonal cluster sensor network is proposed. The performance of...
This paper describes a method of grasp point detection from an item of cloth with unarranged shape. We focus on the combination of grasp point detector with shape classifier. In the proposed method, Convolutional Neural Network(CNN) is generated for shape classification, and it is also used for extracting a feature vector that presents shape characteristics. Using the feature, grasp points are calculated...
The main aim of this paper is to reduce the computational time, to increase the complexity ratio and to improve the image quality by applying dither Dither Block Truncation coding algorithm with different similarity comparison algorithm, as different approaches are followed to improve the quality of an image, ODBTC is one of the approach, but to improve the quality we will also include some of the...
In this paper, we present a method to evaluate earthenware having a rotational shape by using ellipses. The rotational shape is a typical shape that is encountered in the archeological study of earthenware. The distortion in this shape differs according to the habits and methods of the craftsman. Through calculating the degree of the circularity of the cross sections of a model, the distortion in...
This research aims to study the neural influence of conflict between brand and product performance on consumer decision. In the experiment, stimuli of products with brand and performance information were displayed randomly. 22 subjects need to decide whether to buy, while the event-related potentials (ERPs) were recorded. The stimuli were divided into four conditions based on the consistency of brand...
Video segmentation has been widely applied in many fields, such as motion identification, target tracking, video retrieval and video editing. We have proposed an approach of video segmentation, which combines the color feature, shape feature and motion information of the target together. Firstly, we introduce tiny amount of interactions into the processing of key frame, obtain the accurate contour,...
In this paper, we present an approach of the generalization of the Spatially-Variant Morphological Operators to the color images, that preserves the concept of the structuring function. Two methods are suggested. The first method is based on total ordering and the second on marginal treatment of each component of the image. For each method, we define the notion of Spatially-Variant (SV) structuring...
In this study, a method realizing real-time color-tunable white light-emitting diodes (LEDs) through the combination of phosphor patterns and adaptive liquid lens is proposed. The phosphor patterns with red ring and yellow ring was fabricated on an Indium Tin Oxides glass (ITO glass) plate by the screen printing process. The ITO glass is set to be the electrode to change the lens shape. And a liquid...
Computer Game is one of the important and challenging research directions in the field of Artificial Intelligence (AI).
