Abstract – This paper presents hand sign recognition using radial basis function algorithm implemented in VHDL. Radial Basis Function Neural Network has a simple structure and a fast training process. The hand sign recognition system has 3 steps: 1) Image pre-processing, 2) Feature extraction and 3) Classification. An image is pre-processed and converted to feature vector which will be compared with the training set image feature vectors. The system was designed to recognize 24 American sign languages hand signs. The proposed ANN leads to 100% recognition rate for the training set. This hand posture recognition system is coded using VHDL and Matlab, simulated using ModelSim 10.0b and Matlab R2012. 

Keywords— Hand posture recognition, Radial Basis Function Neural Network (RBFNN), Self organizing Map (SOM), American Sign Language (ASL)
