What code?
The general answer is obviously no. You are not going to find any code which will universally discern intent and isolate any arbitrary and undefined foreground region from any arbitrary and undefined background region in any one of countless unspecified "types" of images, many of which MATLAB can't even open.
The more magical properties a solution requires, the more certain it is to not exist.

Try this:
% Display mask with 50% transparency over the "gray" image.
imshow(gray);
hold on;
h = image(255 * mask);
h.AlphaData = 0.5;

There are several ways to remove the background from an image and perform edge detection on the remaining object. Here are some methods:
Using a photo editing software like Adobe Photoshop or GIMP: You can use the selection tools like Magic Wand, Lasso, or Quick Selection to select the background and delete it. Then, use the Edge Detection filter or tool to highlight the edges of the remaining object.
Using online tools: There are many free online tools like remove.bg, Clipping Magic, or Canva that allow you to remove the background of an image automatically. After removing the background, you can use the image editor in these tools to apply edge detection on the remaining object.
