| 1 | A real-time hand-signs segmentation and classification system using fuzzy rule based RGB model and grid-pattern analysis显示文摘Computer vision based researches of automatic hand-signs classification using simple camera based image are increasing rapidly in the present world.Hand-signs are the basic unit of the sign languages.So,successful sign language recognition depends on the recognition or classification of handsigns successfully. The contributions of the proposed system are in three areas:1)Hand-signs detection and segmentation using proposed fuzzy rule based RGB (FRB-RGB)model combining with Haar-classifiers and motion queue in cluttered and dynamic background with illumination variation environment; 2)Rotation,translation and scale invariant window-grid vector (WGV)is proposed for feature vector;3)We have proposed simple mathematical analysis based classifier that classifies the hand-signs accurately in real-time. | Muhammad Aminur RAHAMAN Mahmood JASIM Md.Haider ALI Tao ZHANG Md.HASANUZZAMAN | 2018 | Frontiers of Computer Science2018，12，6： | 1 |
| 2 | Bangla language modeling algorithm for automatic recognition of hand-sign-spelled Bangla sign language显示文摘Because of using traditional hand-sign segmentation and classification algorithm,many diversities of Bangla language including joint-letters,dependent vowels etc.and representing 51 Bangla written characters by using only 36 hand-signs,continuous hand-sign-spelled Bangla sign language(BdSL)recognition is challenging.This paper presents a Bangla language modeling algorithm for automatic recognition of hand-sign-spelled Bangla sign language which consists of two phases.First phase is designed for hand-sign classification and the second phase is designed for Bangla language modeling algorithm(BLMA)for automatic recognition of hand-sign-spelled Bangla sign language.In first phase,we have proposed two step classifiers for hand-sign classification using normalized outer boundary vector(NOBV)and window-grid vector(WGV)by calculating maximum inter correlation coefficient(ICC)between test feature vector and pre-trained feature vectors.At first,the system classifies hand-signs using NOBV.If classification score does not satisfy specific threshold then another classifier based on WGV is used.The system is trained using 5,200 images and tested using another(5,200×6)images of 52 hand-signs from 10 signers in 6 different challenging environments achieving mean accuracy of 95.83%for classification with the computational cost of 39.972 milliseconds per frame.In the Second Phase,we have proposed Bangla language modeling algorithm(BLMA)which discovers all'hidden characters'based on'recognized characters'from 52 hand-signs of BdSL to make any Bangla words,composite numerals and sentences in BdSL with no training,only based on the result of first phase.To the best of our knowledge,the proposed system is the first system in BdSL designed on automatic recognition of hand-sign-spelled BdSL for large lexicon.The system is tested for BLMA using hand-sign-spelled 500 words,100 composite numerals and 80 sentences in BdSL achieving mean accuracy of 93.50%,95.50%and 90.50%respectively. | Muhammad Aminur RAHAMAN Mahmood JASIM Md.Haider ALI Md.HASANUZZAMAN | 2020 | Frontiers of Computer Science2020，14，3： | 0 |
