Identification and apprehension of criminals by matching facial sketches with photographic faces is one of the major law enforcement applications of the modern world. Majority of the crime occur where there will not be any information available regarding the suspect. In such situation, forensic sketch artist who usually deals with the eyewitness of the crime or victim in order to draw the sketch that...
This paper proposes detection of anomaly acoustic scenes based on a temporal dissimilarity model. The periodicity in the temporal variation of acoustic scenes is first pointed out and then used to build a new stochastic model. In the new model, the temporal variation is expressed by dissimilarity between current and previous acoustic scenes. Anomaly acoustic scenes are detected based on the 24-hour...
Software defined networking (SDN) provides flexible management for datacenter networks with the flow-level control. Such the fine-grained management, however, consumes large amount of bandwidth between data and control planes, which results in the bottleneck in the scalability of SDN-based datacenters. "The elephant and mouse phenomenon" suggests that there are only very few elephant flows...
Poor sitting postures influence one's health and can cause upper limb and neck disorder. Current solutions for siting posture recognition, however, are impractical due to intrusiveness, high cost or low generalization capability. Particularly, most of the existing solutions are chair-dependent, which are highly coupled with certain types of chairs. In this paper, we design Postureware, a smart cushion,...
This paper presents a study about estimating the emotions conveyed in clips of background music (BGM) to be used in an automatic slideshow creation system. The system we aimed to develop, automatically tags each given pieces of background music with the main emotion it conveys, in order to recommend the most suitable music clip to the slideshow creators, based on the main emotions of embedded photos...
There is a growing need for Vehicular Ad-hoc Networks (VANETs), in which vehicles communicate with each other (i. e., Vehicle to Vehicle, V2V) or with the infrastructure (i. e., Vehicle to Infrastructure, V2I) on a wireless basis. This paper presents an improved traffic monitoring system for VANET applications via a proposed security scheme. Specifically, the proposed model analyzes the monitored...
This paper introduces automatic framework brain tumor detection, which detects and classify brain tumor in MR imaging. The proposed framework brain tumor detection is an important tool to detect the tumor and differentiate between patients that diagnosis as certain brain tumor and probable brain tumor due to its ability to measure regional changes features in the brain that reflect disease progression...
Annotation of multimodal data sets is often a time consuming and a challenging task as many approaches require an accurate labeling. This includes in particular video recordings as often labeling exact to a frame is required. For that purpose, we created an annotation tool that enables to annotate data sets of video and inertial sensor data. However, in contrast to the most existing approaches, we...
Biological information can easily be monitored by installing sensors in a lavatory bowl. Lavatories are usually shared by several people, so users need to be identified. Because of the need for privacy, using cameras, microphones, or scales is not appropriate. Though personal identification can be done using a touch panel, the user may forget to use it because the action is not necessary. In this...
In this paper, we present an approach for person identification using morphing footsteps measured from a fabric-based pressure mapping sensor system. The flexible fabric sensor is 0.5 mm thin and operates under a 5 mm thick normal carpet; therefore, it can be easily implemented into modern smart living spaces. We extract features concerning single steps with the shifting of gravity center, maximum...
Gesture recognition is one of the emerging fields in industry and a hot research topic in academia. It is commonly used in smart devices to assist the owners in their day-to-day life. But it is also important in facilitating processes in any kind, that involves people. In our attempt at improving life quality for disabled people below the neck, an assistive autonomous powerchair is developed. To ease...
The main aim of recognising gestures is to build a system that can identify human gestures that are specific and then to use them to put forth desired information to the device. By using mathematical algorithms, human gestures can be interpreted. This is referred to as Gesture Recognition. Mudra is an expressive form of gesture that is mainly used in Indian classical dance form where the gesture is...
Software companies are dealing with large number of software bugs daily. Bug triage fixes bug by properly assigning a developer to a new bug. Software companies spend heavy amount in dealing with these bugs. For reducing time and cost of bugs triaging automated approach is required which assigns new bug to a developer with relevant experience to solve the new coming report. To reduce the scale of...
Nowadays image manipulation plays an important role due to the powerful photo editing software such as Picasa, Photoshop so that it looks like as original. Such tampering with the original digital image is called as image forgery. The detection of image forgery in an image is important so it can be used as legal evidence in investigations such as court and other fields. Many Images are used as genuine...
In the recent years, online reviews are one of most important source of customer opinion. Nowadays consumer can gain knowledge about the products and service from online review resources, using which they can make decisions. This may lead to Opinion Spam, where spammers may manipulate and fake reviews to promote artificially or devalue the products and other services. Opinion spam detection is done...
Stack Overflow is one of the most popular question-and-answer sites for programmers. However, there are a great number of duplicate questions that are expected to be detected automatically in a short time. In this paper, we introduce two approaches to improve the detection accuracy: splitting body into different types of data and using word-embedding to treat word ambiguities that are not contained...
Networked Virtual Environments (NEV) are sets of disjointed virtual worlds which are topographically set apart from the users yet connected through the communication network to give them the illusion of being in the same virtual location. NVEs are increasingly receiving consideration from business and research point of view. Contrasted with various sorts of possible applications, NVEs require a high...
In this paper, we propose a SaaS service which prevents shoplifting using image analysis and ERP. In Japan, total damage of shoplifting reaches 450 billion yen. Based on cloud and data analysis technology, we propose a shoplifting prevention service with image analysis of security camera and ERP data check for small shops. We evaluated movie analysis.
The large number of video lectures within digital archives is making critical the indexing and retrieval process. Indeed, most of the systems base the indexing process on few generic text information (e.g., course title and teacher's name) and this creates problems to students who are looking for very specific topics and hence want to browse video in details. Moreover, additional metadata could provide...
Breast cancer is an life threatening disease in USA and UK. It is also one of the major diseases that has greater death rate. Cancer is the erratic growth of cells that originate in the blood tissue and Tumours may be malignant or benign. Early detection increases the chances of survival and reduces the death rate. This paper compares the approach to classify the mammogram based on the features extracted...
