Removing the background using the light pattern for segmentation

In this section, we are going to develop a basic algorithm that will enable us to remove the background using a light pattern. This preprocessing gives us better segmentation. The input image without noise is as follows:

If we apply a basic threshold, we will obtain an image result like this:

We can see that the top image artifact has a lot of white noise. If we apply a light pattern and background removal technique, we can obtain an awesome result in which we can see that there ...
