The main Tesseract.js functions (ex. recognize, detect) take an image parameter, which should be something that is like an image. What's considered "image-like" differs depending on whether it is being run from the browser or through NodeJS.
On a browser, an image can be:
- an
img,video, orcanvaselement - a
Fileobject (from a file<input>) - a
Blobobject - a path or URL to an accessible image
- a base64 encoded image fits
data:image\/([a-zA-Z]*);base64,([^"]*)regexp
In Node.js, an image can be
- a path to a local image
- a Buffer storing binary image
- a base64 encoded image fits
data:image\/([a-zA-Z]*);base64,([^"]*)regexp
