The Car’s backup camera image manipulation

The project is to manipulate the guiding lines in the backup camera of a car.

We need to make a user interface that allow us to manipulate the guiding lines.

The user interface adjusts the length and width of the guiding lines on the image to display inaccurate measurements.

•  Make the length shorter or longer

•  Make the width skinnier or wider

this is an image from a backup camera or a car

 first step:

remove the guiding lines from the image. (cover the colored pixels with background color)

 second step:

draw similar guiding lines next to the existing lines. (green, yellow, red) 

 Third step:

Draw new guiding lines with different inaccurate measurements.

For example, make them closer to the center or closer to the edges.

 We need images and code for each step. Each step should be separate.
