How to separate the foreground from the background of the image?

Hi,

How to separate the foreground from the background OR how to remove the background of an image?

Below are a few example images and background removed by commercial products available on the market.

How to achieve the same/similar effects in Matlab?

Can anyone share some thoughts please? Very much appreciated.

Hi @Salad Box,

In order to achieve the desired task of separating foreground from the background of the provided images, consider using 'Image Segmenter' app. Refer to this MathWorks documentation to know about the 'Image Segmenter' app:

Also, consider using this File Exchange tutorial provided by @Image Analyst: https://www.mathworks.com/matlabcentral/fileexchange/25157-image-segmentation-tutorial?s_tid=srchtitle

Another approach which can be used in this case could be to use 'grabcut' function which extracts the region of interest from the image as defined by the user. Follow the example given in this MathWorks documentation to know more about this:

Hope this helps! Thanks.
