Gestures are a powerful means of communication between two deaf humans. This document basically describes how to recognize alphabetic signs from A to Z, numbers from 0 to 9, and additional punctuation marks such as question mark, period, and space. Say no to plagiarism.

Nowadays, human-computer interaction (HCI) has developed. HCI came into the picture for deaf people to indicate sign language. HCI basically deals with some methods such as computer vision and speech recognition. Computer vision is used to extract the most important data of the image and acquire the image with the help of image processing. Speech recognition basically handles the input speech in the form of NATO phonetic alphabet also known as International Civil Aviation Organization (ICAO) phonetic alphabet provided by the person in any respective language. Brief description Sign language Sign language is described through the combination of hand gestures, hand movement, body and face. Education and training have become faster and easier for deaf people through the use of sign language. For deaf and dumb people it is important to convert sign language into plain text and the given text into sign language. Sign language recognition is done in three different categories; Glove-based analysis Device-based analysis Vision-based analysis. Sign language represents the dynamic gesture of the hand, body and face to produce speech; it also represents static hand gestures to produce numeric letters and numbers. Sign languages ​​are used to produce more intentional and accurate speech. Hand Gesture Hand gesture basically involves the use of skeleton as it can also describe the definition of sign languages. There are two methods to describe hand gesture recognition: Static hand gesture – A process in which there is no movement and the hand is always kept stable. Dynamic hand gesture – A process in which there is movement after a particular interval which depends on a period of time. Image Processing Image processing is a process used to convert the original image into an enhanced image by performing some operations. Morphological operations are image processing that handles and processes the binary image. Erosion and dilation are two fundamental morphological operations. Image processing is basically considered as a signal processor as it takes images as input and produces an enhanced image as output. Image Capture Image capture is a process used to capture an image of a person making a hand gesture through the camera. It is used so that indirect understanding of the person does not occur when the other person makes a gesture with their hands. The image capture can be a grayscale image or an RGB image depending on the.
