or set EasyAR SDK License Key & specify images to recognise

window.ImageRecognition.init("EasyAR_SDK_License_Key",{
    "images":[{
        "image": "test.jpg", //image path in www folder
        "name" : "test" //name that return when this image detected

    }]
});

2. Start

Later in your application, simply call the start to open camera and start looking for images.

function successCallback (res) { alert(res); }
function failureCallback (err) { alert(err); }
window.ImageRecognition.start(successCallback, failureCallback);

when camera recognise one of the specified images, successCallback will called and it will pass the recognised image name as argument.
