Due to the frequent occurrence of the traffic accidents, the passive safety devices fail to meet people's needs. Growing attention has been paid to active safety strategies such as the collision warnings. This paper aims at discovering the related characteristics between the active safety strategy and velocity through the visual analysis of Internet of Vehicles (IoV) warning data. First, seven datasets...
Mining high utility item sets is one of the most important research issues in data mining owing to its ability to consider nonbinary frequency values of items in transactions and different profit values for each item. Although several studies have been carried out, current methods present the mined results in the form of textual lists for users, which degrades the understand ability of the discovered...
Technique for horror video recognition is important for its application in web content filtering and surveillance, especially for preventing children from being threaten. In this paper, a novel horror video recognition algorithm based on fuzzy comprehensive evolution model is proposed. Three low-level video features are extracted as typical features, and they are video key-light, video colour energy...
Detection of Region of Interest (ROI) in a video leads to more efficient utilization of bandwidth. This is because any ROIs in a given frame can be encoded in higher quality than the rest of that frame, with little or no degradation of quality from the perception of the viewers. Consequently, it is not necessary to uniformly encode the whole video in high quality. One approach to determine ROIs is...
Although many papers have been published on visual tracking, visual servoing of the vision-based robotics, there are only few research study on using vision to improve the standing and walking stabilization for legged robots. In this paper, we set two cameras as the humanoid's eyes, to observe a static object in front, and using the visual measured information to control the robot keeping a desired...
The packaging of goods is a language which tells the customers the attributes, functions, connotation, taste and cultural meaning of products. In this paper, the basic theory of semiotics is used to interpret the semiotic meaning of packaging, and the concept of packaging semantics is put forward. First, some basic element, such as symbols, semiotics, and product semantics are discussed in brief....
In this paper, we propose a new two-way visual servoing method, named as hand & eye-vergence visual servoing. This idea stems from animal's evolution history, predator have evolved their eye positions to be at the front face and their eyes turn to gaze at the target prey to be suited to triangulation, enhancing the ability to measure precisely the distance to the prey for catching it. This animal's...
Intention-oriented computational visual attention (ICVA) model attempts to imitate human vision by computational intelligence. This paper contributes to enabling the ICVA model with learning ability so as to acquire or change intention according to assigned image samples. This innovative design is called the self-learning ICVA model which contains a neuro-fuzzy network to learn intention from image...
This paper deals with position-based 6-DoF visual servoing. With a common sense of feedback control, we stress that improvement of the dynamics of the sensing unit is important for a stable visual servoing. We propose a method to improve dynamics in visual recognition, with compensating the fictional motion of the target in the camera images based on kinematics of the manipulator, by extracting the...
Segmentation of bone tissue is an important topic in computer assisted medical image analysis. In particular, automatic segmentation of femoral head and acetabulum from CT dataset of hip joint respectively is of importance for various corresponding clinical tasks including visualization, quantitative assessment, early diagnosis and adequate management of patients suffering from avascular necrosis...
