Abstract
There are a lot of people who have many disabilities in our world out of which,people who are deaf and dumb cannot convey there messages to the normal people. Conversation becomes very difficult for this people. Deaf people cannot understand and hear what normal people is going to convey ,similarly dumb people need to convey their message using sign languages where normal people cannot understand unless he/she knows or understands the sign language. This brings to a need of an application which can be useful for having conversation between deaf,dumb and normal people. Here we are using hand gestures of Indian sign language (ISL) which contain all the alphabets and 0-9 digit gestures. The dataset of alphabets and digits is created by us.After dataset building we extracted the features using bagof- words and image preprocessing.With the feature extraction, histograms are been generated which maps alphabets to images. Finally, these features are fed to the supervised machine learning model to predict the gesture/sign. We did also use CNN model for training the model.
