Where, (p1,p2),(p3,p4) are 2 vertical lines anf (p5,p6) is horzontal line. The total points for each eye is six since we are considering two vertical lines and two horizontal lines. EAR Formulation: EAR (Eye Aspect Ratio) can be calculated by below formula where each point represents landmark of eye’s X and Y co-ordinate.Translate word string and convert it into speech.Append the character to a string to form a word.
Map matching character for the sequence.Append dits and dahs to create a sequence.If yes that’s a blink, then find out whether it’s a long or short blink based on duration.Check if the EAR’s values are less than the threshold value.Calculate initial EAR’s (Eye Aspect ratios).Apply mediapipe’s face mesh model on input and initialize Morse code.Connect your cam to OpenCV and load the live input or give already recorded video.Bringing real-time augmented reality (AR) applications, a transform module bridges the gap between face landmark estimation and useful AR applications that are commonly used in everyday life. Face Mesh model allows users to map 468 3D landmarks upon a face. Face Mesh Model is a model which is used frequently by developers. There are various ML solutions available such as Face Mesh model, Object-detection, pose, hands, holistic, Box tracking and many more. Mediapipe is a google api offers cross-platform, customizable ML solutions for live and streaming media. Our approach is by using mediapipe and openCV. Using openCV and tree-based algorithms.Using CNN (Convolutional Neural Network) or MTCNN (Multi-Task Cascaded Convolutional Neural Network) which in turn uses three different layers.Morse code translation can be done can be done using may technologies some of the projects are there are a lot of projects which detect faces and eye blinks. Technology has a wide area which updates day by day, there are various technologies used to convert various forms of morse codes, sign languages Etcetera.
#BLINKING MORSE CODE TRANSLATOR SOFTWARE#
but one to receive it and understand message given in morse code must know morse code, but now one can simply use this software upload the video and convert the morse code to text, speech and also into any other language they know this software allows users to translate morse code in an efficient, user friendly and cost-effective manner. This example shows how one can use Morse code in many situations. (J– March 28, 2014) was an American politician and military officer, while answering questions Denton blinked his eyes in Morse code, spelling the word "T O R T U R E" and sent a secret message through his eyes to his US NAVAL peers. As mentioned, we are using Eye blinks to communicate through Morse code, A short blink is a dit and a long blink is a dah and sequence of the is an alphabet these alphabets together form a word. The current or wave is present during the dit or dah's duration and missing between dits and dah's duration. Morse code is frequently communicated through an information-carrying medium such as visible light, radio waves, or sound waves, which is keyed on and off in sequence. There is a space of duration equal to three dots between each letter of a word, and seven dots separate words Morse code can be memorised and sent in a form that is apparent to human senses, such as sound waves or visible light, eye blinks, so that it can be directly deciphered by people who have learned the technique. Normally, after each dit or dah in an encoded character, there is a signal absence, called a space, which is equal to the dit duration. dah is generally three times longer than a dit.
Morse code transmission is measured by dit durations. Morse code is accompanied with sequence of dits and dahs. In the Morse code there are 26 letters from a to z, one non-Latin letter, numbers, and a small set of punctuations and procedures (signs). Morse code is a communication process that uses two distinct signal durations to encode text characters. Disability can be caused due to many reasons, from birth or other medical conditions so every communication mode is not Feasible for every person or the person with whom he/she is trying to communicate.Īlso, some people want to communicate in secret so that they can pass messages to specified person in presence of third person who will have no knowledge about that mode, this can be done using Morse code. People communicate using any of the modes mentioned, but some persons are disable, disability can be of many forms like deaf, dumb, blind Etcetera. Communication is a process which is essential in day-to-day life for a person, every person has needs to communicate with people, the mode of communication can be any, it can be either speech, text, signs Etcetera.
