Abstract: The idea of gesture recognition plays a vital role in human machine interaction in which the perception of human gestures by a computer is utilized. The main usage of gesture recognition research is in detecting a particular human gesture and convey the information related to each gesture to the user. After the identification of specific gesture of interest from the collection of gestures, clear-cut command for execution of action can be given to remote system. It is intended to make the computer understand human body language, thereby removing the gap between machine and human. Without depending on conventional input methods we can make use of gesture recognition to enhance human–computer communication. Using this approach, it is aimed to improve the effectiveness and efficiency of gesture recognition by providing an alternative method with some advancement in gesture identification and rectification using the calculations related to slop.
