-   Initialize your output stream, and your path, and import in the Image library

    .. code-block:: python

        from IPython.display import Image

        %env DISPLAY=:0
        %env PROGRAM_PATH=/home/zeta/jetson-inference/build/aarch64/bin
        %env INPUT_PATH=/home/zeta/jetson-inference/build/aarch64/bin/images
        %env OUTPUT_PATH=/home/zeta/jetson-inference/build/aarch64/bin/images/test

        input_path='/home/zeta/jetson-inference/build/aarch64/bin/images'
        output_path='/home/zeta/jetson-inference/build/aarch64/bin/images/test'



-   Check all the available any pictures within the system

    .. code-block:: python

        !ls $INPUT_PATH/*


    .. thumbnail:: /_images/background/background_1_list.png

-   Pick one of the image and initialize the image/ output name. 

    .. code-block:: python

        image_name = 'ChangeMe'
        output_name1 = 'background_remove.jpg'
        output_name2 = 'background_replace.jpg'
        %env IMAGE_NAME = $image_name
        %env OUTPUT_NAME = $output_name

        Image(filename=input_path+'/'+image_name) 

|

-   Remove the background!

    .. code-block:: python

        %%capture
        !python3 $PROGRAM_PATH/backgroundnet.py --network=u2net $INPUT_PATH/$IMAGE_NAME $OUTPUT_PATH/$OUTPUT_NAME1


-   Show the resulting image


    .. code-block:: python

        Image(filename=output_path+'/background_remove.jpg') 


    .. thumbnail:: /_images/background/background_2_remove_result.jpg

-   Change the background!

    .. code-block:: python

        %%capture
        !python3 $PROGRAM_PATH/backgroundnet.py --network=u2net --replace=$INPUT_PATH/Ulleung_0.jpg $INPUT_PATH/$IMAGE_NAME $OUTPUT_PATH/$OUTPUT_NAME2



-   Show the resulting image


    .. code-block:: python

        Image(filename=output_path+'/background_replace.jpg')
