Capture-OTP CLI

This CLI application is designed to capture an image from the webcam, perform OCR (Optical Character Recognition) on the captured image, and extract any numeric values with a length of four or more digits from the recognized text. The application utilizes the Go programming language and two external libraries: "gocv" for webcam access and image processing, and "gosseract" for OCR functionality.

2. Install the required external libraries using go get:

go get github.com/otiai10/gosseract/v2
go get -u -d gocv.io/x/gocv
cd $GOPATH/src/gocv.io/x/gocv
make install

1. Build the application using go build:

1. Run the application from the command line:

./capture-otp [-show-window|-sw]

Optional flags:
