Kudan seams to be not supporting this feature in unity
i think it's supported in the native SDKs.
Unlike the native SDKs, the Unity Plugin can't just get a raw image file from the assets and load it into the tracker. This is a feature we will be adding to the plugin in the future.
source :- https://kudan.readme.io/docs/markers-1
EasyAR on the other hand support creating imageTarget out of .png or .jpg one image at a time or by .json to add multiple images in one batch
and it's provided in the example projects in EasyAR_SDK_2.2.0_Basic_Samples_Unity here
Note:- to run the example project you need to
1 - sign up on their site https://www.easyar.com/
2 - creat SDK license key from here.
3 - follow this Guide to place the key and run on unity.
4 - Your goal is achieved in the "HelloARTarget" project
and here is the example project script loading an AR experience from .pjg images
using UnityEngine;
using System.Linq;
using EasyAR;
namespace Sample
{
public class HelloARTarget : MonoBehaviour
{
private const string title = "Please enter KEY first!";
private const string boxtitle = "===PLEASE ENTER YOUR KEY HERE===";
private const string keyMessage = ""
+ "Steps to create the key for this sample:\n"
+ " 1. login www.easyar.com\n"
+ " 2. create app with\n"
+ " Name: HelloARTarget (Unity)\n"
+ " Bundle ID: cn.easyar.samples.unity.helloartarget\n"
+ " 3. find the created item in the list and show key\n"
+ " 4. replace all text in TextArea with your key";
private void Awake()
{
if (FindObjectOfType<EasyARBehaviour>().Key.Contains(boxtitle))
{
#if UNITY_EDITOR
UnityEditor.EditorUtility.DisplayDialog(title, keyMessage, "OK");
#endif
Debug.LogError(title + " " + keyMessage);
}
}
void CreateTarget(string targetName, out SampleImageTargetBehaviour targetBehaviour)
{
GameObject Target = new GameObject(targetName);
Target.transform.localPosition = Vector3.zero;
targetBehaviour = Target.AddComponent<SampleImageTargetBehaviour>();
}
void Start()
{
SampleImageTargetBehaviour targetBehaviour;
ImageTrackerBehaviour tracker = FindObjectOfType<ImageTrackerBehaviour>();
// dynamically load from image (*.jpg, *.png)
CreateTarget("argame01", out targetBehaviour);
targetBehaviour.Bind(tracker);
targetBehaviour.SetupWithImage("sightplus/argame01.jpg", StorageType.Assets, "argame01", new Vector2());
GameObject duck02_1 = Instantiate(Resources.Load("duck02")) as GameObject;
duck02_1.transform.parent = targetBehaviour.gameObject.transform;
// dynamically load from json file
CreateTarget("argame00", out targetBehaviour);
targetBehaviour.Bind(tracker);
targetBehaviour.SetupWithJsonFile("targets.json", StorageType.Assets, "argame");
GameObject duck02_2 = Instantiate(Resources.Load("duck02")) as GameObject;
duck02_2.transform.parent = targetBehaviour.gameObject.transform;
// dynamically load from json string
string jsonString = @"
{
""images"" :
[
{
""image"" : ""sightplus/argame02.jpg"",
""name"" : ""argame02""
}
]
}
";
CreateTarget("argame02", out targetBehaviour);
targetBehaviour.Bind(tracker);
targetBehaviour.SetupWithJsonString(jsonString, StorageType.Assets, "argame02");
GameObject duck02_3 = Instantiate(Resources.Load("duck02")) as GameObject;
duck02_3.transform.parent = targetBehaviour.gameObject.transform;
// dynamically load all targets from json file
var targetList = ImageTargetBaseBehaviour.LoadListFromJsonFile("targets2.json", StorageType.Assets);
foreach (var target in targetList.Where(t => t.IsValid).OfType<ImageTarget>())
{
CreateTarget("argame03", out targetBehaviour);
targetBehaviour.Bind(tracker);
targetBehaviour.SetupWithTarget(target);
GameObject duck03 = Instantiate(Resources.Load("duck03")) as GameObject;
duck03.transform.parent = targetBehaviour.gameObject.transform;
}
targetBehaviour = null;
}
}
}
edit
although it's easy to make an ImageTarget from .png but i wonder how to check that the image contains the sufficient features for being detected in EasyAR ?
Google AR Core supports this feature but they have limited number of supported devices

Looks like Vuforia is supporting the creation of the image target at runtime. also drag and drop the image as texture in the editor without having to generate a dataset from the portal. although you still need the api key from the portal.
