Thanks to suzuki for compiling tesseract in this post http://tinsuke.wordpress.com/2011/11/01/how-to-compile-and-use-tesseract-3-01-on-ios-sdk-5

I have included an index.html with an example.

It uses the camera function with destinationType.FILE_URI (IMPORTANT!!!)

        // A button will call this function
        //
        function capturePhoto() {
            // Take picture using device camera and retrieve image as base64-encoded string
            navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 100,
                                        destinationType: destinationType.FILE_URI });
        }
        
        // Call the plugin when a photo is successfully retrieved
        //
        function onPhotoURISuccess(imageURI) {
            callNativePlugin({url_imagen: imageURI});
        }
        

        function callNativePlugin( returnSuccess ) { 
            OCRPlugin.callNativeFunction( nativePluginResultHandler, nativePluginErrorHandler, returnSuccess ); 
        } 
        
        function nativePluginResultHandler (result) { 
            alert("ok: "+result);
        } 
        
        function nativePluginErrorHandler (error) { 
            alert("error: "+error);
        }
