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

Human-computer interaction (HCI) has developed nowadays. HCI came in 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 from the image and acquire the image using image processing. Speech recognition essentially handles speech input in the form of the NATO Phonetic Alphabet, also known as the International Civil Aviation Organization (ICAO) Phonetic Alphabet, given by the person in any respective language. Brief descriptionSign languageSign language is described by a combination of hand gestures, hand movements, body and face. Education and training have become faster and easier for deaf people through the use of sign language. For deaf and mute people, it is important to convert sign language into normal 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 a dynamic hand gesture that uses the hand, body, and face to produce a word; it also depicts static hand gestures to produce letters and numbers. Sign languages ​​are used to produce more intentional and precise words. Hand Gesture Hand gesture basically involves the use of skeleton as it can also describe defined sign languages. There are two main methods to describe hand gesture recognition: Static hand gesture – A process in which there is no movement and the hand always remains stable. Dynamic Hand Gesture – A process in which there is a movement after a particular interval which depends on a period of time. .Image ProcessingImage processing is a process used to convert the original image into enhanced image by performing certain operations. Morphological operations are image processing that exploits and processes the binary image. Erosion and dilation are two fundamental morphological operations. Image processing is basically considered a signal processor because it takes images as input and produces an enhanced image as output. Image Capture Image capture is a process used to capture the image of a person making a hand gesture through the camera. It is used to prevent indirect understanding of a person from occurring when another person gestures with their hands. The capture..
