Some techniques about the posture estimation of driver's head are existed, like detecting the sight line from the position of the pupil and iris of the eyes, using the positional relationship between the eyes and nose, and so on. However, there is a problem that the result of image measuring is influenced by ambient light and face makeup of the driver in these techniques. And then, it cannot estimate a wide range of face direction. In order to solve this problem, we propose a technique of estimate the head posture of the driver by three-dimensional (3-D) image analysis which is based on the infrared pattern projection technique. The technique we proposed includes two portions: one is 3-D image measurement of driver's head and the other is the head posture estimation by 3-D image analysis. As the 3-D image measurement method, in order to obtain a reliable 3-D image, we use slit pattern projection technique; in order to keep the 3-D measurement accurate of the portion near the nose, and the 3-D measurement speed, we only use three stripes to project on the face; in order to reduce the influence of external light on the people's body, we use infrared pattern projection. To estimate the head posture quickly, we face contour modeled as linear approximation, and then use the relationship between the face degree and the slope of the line to judge the face direction.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"4 1","pages":"377-383"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78903593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On one hand, the definitions of cloud services are misunderstood or misapplied; on the other hand, neither governments/enterprises are fully prepared for the new phenomena, nor have the shift paradigms been established. As a result, many failure examples are found in the transformation to cloud environment. Business process reengineering created a revolutionary tide in many businesses in late of the 20th century. Business put a lot of efforts to examine and change processes radically to improve performance. As the concept of energy saving and environmental protection has got great attentions around the world, the term Green BPR that focuses on the redesign of the processes within and between enterprises to meet the characteristics of green IT gives a new definition to BPR. This research aims to combine the concept of BPR and GBPR to set up a paradigm for could migration so that the enterprises can be transformed to cloud successfully. The research agenda that applies BPR and gBPR in cloud migration is proposed in this paper. The framework of the paradigms of the migration to cloud is established as well.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"13 1","pages":"460-465"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78950614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, based on the blocking artifact characteristics matrix (BACM), we propose a method to detect seam carving in natural images without knowledge of the original image. In detail, for the original JPEG images, the BACM exhibits regular symmetrical shapes; for the images that are damaged, the regular symmetrical property of the BACM is destroyed. After found BACM from images, we define 18 features to detect the damage from BACM to train a support vector machine (SVM) classifier for recognizing whether an image is an original or it has been modified by seam-carving. We show that BACM is useful for detect the damage by seam-carving in JPEG format images.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"4 1","pages":"632-638"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81579068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various strategies have been tested for achieving this issue such as seam carving. It can retain the crucial objects and remove the insignificant pixels repeatedly, resulting in the content-aware image/video. Such ordinary method presents vital problem is that it could destroy the line structure and shape of the object, which can be easily find out by the viewers. The video seam carving will also cause the continuous problem because of the motion. In this paper, we provide the state-of-the-art strategies focus on maintaining the perspective line structure in video, especially in vehicle video recorder.

With the popularity of text based communication tools, customers can easily express their opinions about purchased products or services. Generally speaking, the on-line reviews should be unbiased reflections of the consumers' experiences with the products or services. However, some comments are biased \"manipulation\", which might reduce consumers' purchase intentions and bring a great damage to enterprisers. Although the existence of manipulation has been assumed widely, there are few results available in the literature for manipulation detection. This study aims to improve the performance for manipulation detection through feature selection. The study is divided into three parts. In the first part, we use conventional feature vectors obtained directly from the text files, and show that these feature vectors are in fact not useful for manipulation detection. In the second part, we adopt eight features recommended in the literature, and show that these features can improve the detection rate significantly. In the third part, we add three new features that can improve the detection accuracy further. A real case study of smart phone is used to illustrate the effectiveness of the proposed features.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"90 1 1","pages":"237-243"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85619602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However many problems remain, making HA (Home Agent) a point of failure for handover procedures, and producing handover delays that can degrade the quality of communication for real-time applications. The authors proposed an improved handover procedure in which a DDNS (Dynamic DNS) server notifies a BU (Binding Update) message to CNs (Correspondent Nodes) without authentication via HA, but the method also incurred long handover delays and a large packet loss rate. This paper proposes a new mobility support procedure in IPv6 Networks with DDNS servers, which no longer supports MIPv6.

The feature of this system is to generate a variety of language expressions from combinations of different syntactic structures and different sets of vocabulary, while managing the generation process based on the user-designated viewpoints. The system converts the visual information into a concept dependency structure using a semantic representation framework proposed by Takagi and Itoh. The system then transforms the structure and divides it into a set of words, deriving a word dependency structure, which is later arranged into a sentence. The transformation of a concept dependency structure and the variation in word segmentation allow the system to generate a variety of sentences from the same visual information. In this paper, we employ user-designated viewpoints to scenes containing more than one object. We designed the parameters of the user-designated viewpoints which enable the system to manage the generation process and to generate a variety of expressions. An evaluation has confirmed that the system generates certain variations according to parameter values set by the user. The variations include expressions referring to attribute values of the objects in the scenes and relative expressions denoting the relations between the targeted object and others.","PeriodicalId":68697,"journal":{"name":"炎黄地理","volume":"17 1","pages":"322-328"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74853483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
