Peruvian sign language recognition using low resolution cameras

Abstract

The recognition of sign language gesture through image processing and Machine Learning has been widely studied in recent years. This article presents a dataset consisting of 2400 images of the static gestures of the Peruvian sign language alphabet, in addition to applying it to a hand gesture recognition system using low resolution cameras. For the gesture recognition, the Histogram Oriented Gradient feature descriptor was used, along with 4 classification algorithms. The results showed that Histogram Oriented Gradient, along with Support Vector Machine, got the best result with a 89.46% accuracy and the system was able to recognize the gestures with variations of translation, rotation and scale.
