An intelligent approach to recognize sign language for deaf and dumb people of the world
Dedication First of all we would like to remember the deaf and dumb people of the world for whom we tried to develop a Sign language Recognizer (SLR).
Outline• Sign language• SLR & its necessity• Helping process of SLR• Working procedure of SLR• Block Diagram of SLR• BP training time & graph• Recognition accuracy• Limitations• Future plan• Papers
What is Sign Language ?? Communicating language used primarily by deaf people. Uses different medium such as hands, face, or eyes rather than vocal tract or ears for communication purpose. Communication using sign language
What is SLR ?? Sign language recognizer (SLR) is a tool for recognizing sign language of deaf and dumb people of the world.
Why we need SLR ??Problems:• About 2 million people are deaf in our world• They are deprived from various social activities• They are under-estimated to our society• Communication problem
Continued..Proposed Solution: SLRSLR can be a desirable interpreter which can helpboth the community general and deaf.
How SLR help ?? An Example.....Suppose a deaf customerwent to a shop. She is ??trying to express herdemands to theshopkeeper using signlanguage but theshopkeeper can notunderstand her demands. shopkeeper Deaf customer
Continued.. SLR brings the solution for this problem>> • SLR capture signs shown by deaf man • Convert the signs to text • This text is shown to shopkeeper Now the shopkeeper can understand the deaf man’s demands
Continued..Sign to text conversion using SLR Sign Converted text
Continued..Text to sign conversion When shopkeeper replied to the deaf customer SLR • Convert text to sign • This sign is shown to the deaf customer Now the deaf man can understand the shopkeeper’s speeches
Continued..Text to sign conversion using SLR Shopkeeper speech/text Sign
Limitations• Due to brightness and contrast sometimes webcam can hardly detect the expected skin color.• Because of the similarity of tracking environment background color and skin color the SLR gets unexpected pixels.
Continued..• Due to almost similar pattern its becomehard to take decision.
