{"title":"Recognition of American sign language using LBG vector quantization","authors":"Krupali Suresh Raut, S. Mali, Sudeep D. Thepade, S. Sanas","doi":"10.1109/ICCCI.2014.6921745","DOIUrl":"https://doi.org/10.1109/ICCCI.2014.6921745","url":null,"abstract":"Sign language is a widely used and accepted standard for communication by people with hearing and speaking impairments. A sign language is a language which uses visually transmitted sign patterns, instead of acoustically conveyed sound patterns, to deliver the meaning. Several ways to generalize the American sign language recognition have been proposed in the past [14] [15]. In this paper, novel method of American sign language recognition with Shape and Texture features has been proposed. Many of the existing systems require the person gesticulating to use special data acquisition devices like data gloves which are expensive and difficult to handle. We proposes a more flexible vision based approach where the person is free from additional equipment. The Shape features and Texture feature are more unique, so a novel technique based on combination of these is derived and proposed here. For extracting shape features standard gradient operator such as Robert, Prewitt, Sobel, Canny, Freichein, Kirsh and Laplace are used and for texture feature vector quantization techniques are used. The gradient mask images of the character images are obtained and then LBG vector quantization algorithm is applied on these gradient images to get the codebooks of various sizes. These obtained LBG codebooks are considered as shape texture feature vectors for American sign language recognition. The database includes 26 for American sign language alphabets taken by 12 different people. The images are saved in a jpeg file format and stored in separate folder. Thus there are total 312 images were use for our project and 8 code book sizes (from 4 to 512). The nearest neighbour (KNN) algorithm is considered as performance comparison criteria for proposed character recognition techniques. The best performance is observed in LBG for codebook size 8 of Canny operator and the next best is seen for codebook sizes 4 of freichein gradient mask for feature extraction. The LBG VQ [11] design algorithm is an iterative algorithm which requires an initial codebook C. This initial codebook is obtained by the splitting method. In this method, an initial code vector is set as the average of the entire training sequence. This code vector is then split into two. The iterative algorithm is run with these two vectors as the initial codebook. The final two code vectors are splitted into four and the process is repeated until the desired number of code vectors is obtained.","PeriodicalId":244242,"journal":{"name":"2014 International Conference on Computer Communication and Informatics","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126850556","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}

Computers have become the life line of today's high-tech world. There is no work in our whole day without the use of computers. When we focus particularly in the field of education, people started preferring to e-books than carrying textbooks. In the phase of learning, visualization plays a major role. When the visualization tool and auditory learning comes together, it brings the in-depth understanding of data and their phoneme sequence through animation and with proper pronunciation of the words, which is far better than the people learning from the textbooks and imagining in their perspective and have their own pronunciation. Scratch with its visual, block-based programming platform is widely used among high school kids to learn programming basics. We investigated that in many schools around the world uses this scratch for students to learn programming basics. Literature review shows that students find it interesting and are very curious about it. This made us anxious towards natural language learning using scratch because of its interesting visual platform. This paper is based on the concept of visual and auditory learning. Here, we described how we make use of this scratch toolkit for learning the secondary language. We also claim that this visual learning will help people remember easily than to read as texts in books and the auditory learning helps in proper pronunciation of words rather than expecting someone's help. We have developed a scratch based tool for learning simple sentence construction of secondary language through primary language. In this paper, languages used are English (secondary language) and Tamil (primary language). This is an enterprise for language learning tool in scratch. This is applicable for other language specific exercises and can be adopted easily for other languages too.","PeriodicalId":244242,"journal":{"name":"2014 International Conference on Computer Communication and Informatics","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123676705","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}

It discusses a project which presents a miniature model of an automated car parking system that can regulate and manage the number of cars that can be parked in a given space at any given time based on the availability of parking spot. Automated parking is a method of parking and exiting cars using sensing devices. The entering to or leaving from the parking lot is commanded by an Android based application. We have studied some of the existing systems and it shows that most of the existing systems aren't completely automated and require a certain level of human interference or interaction in or with the system. The difference between our system and the other existing systems is that we aim to make our system as less human dependent as possible by automating the cars as well as the entire parking lot, on the other hand most existing systems require human personnel (or the car owner) to park the car themselves. To prove the effectiveness of the system proposed by us we have developed and presented a mathematical model which will be discussed in brief further in the paper.","PeriodicalId":244242,"journal":{"name":"2014 International Conference on Computer Communication and Informatics","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114856928","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}

Our analysis indicates that available protocols for WSN are not easily portable for WBAN, specifically Medium Access Control (MAC) Protocols. Thus, we have proposed a new WBAN MAC Protocol based on Aloha protocol which differentiates and preferred various types of traffic based on emergency case.

Due to the changing topology, packet loss is a common phenomenon. Routing protocols used in such type of networks generally based on the assumption that, all participating nodes will be fully cooperative. But, due to the open structure, node misbehavior may exist and so the packet loss occurs. We propose a 2ACK scheme in OLSR protocol with an objective to reduce the node misbehavior. In this paper, we conduct the experiments on NS-2 on existing 2ACK scheme as well as enhanced 2ACK scheme based on OLSR.

In this approach to measuring these factors in an agricultural environment two options to be given that is manually taking measurements and automatic process the sensor data is checking them at various times. If the ability to document the details changes occurred in the sensor field extend this to remote monitoring using Wimax, anywhere we can monitor and control the agricultural field with smart irrigation system using these sensors with the help of Wimax.
