        </p>

        Here is the explanation of the result from the example on the image above:\

        - **box**, indicate the object that the model can detect;
        - **label of the box**, indicate the name of the object that the model detect;
        - **number beside the label**, indicate how much the confidence of the model detect the object;

         ## Tutorial How to Use Ship Detection Model
        Here is the step by step how to use the model on this dashboard:
        - first, **prepare the satellite imagery image** that you want to use. If you don't have the image, you can use this sample image, by clicking the **"Download Image"** on the end of this dashboard usage explanation;
        - then, **choose the model** that you want to use **(on the side bar)**, **YOLOv5x6 Model** to use the YOLOv5x6 model or **Fine-Tuning Model** to use the fine-tuning model (study case: Tanjung Priok Port);
        - to upload your image, **click the "Browse File"** button, then upload your image;
        - after the image is uploaded, **right click the image** and then **copy the image address** by clicking **"Copy image address"** button;
        - then **paste the image address** on the box below the image;
        - finally, **click the "Predict"** button to start the detection of the object inside your image. Wait untill the result appear.
