How to draw a boundary in a cell population?

Greetings, I want to know what techniques can be used to draw the yellow and red boundary in that image? Can I get the general ideas or steps to draw the boundary? I have several images and I want the system to draw it automatically

Use the Color Thresholder on the Apps tab of the tool ribbo to get the non-yellow region as a binary image. Then call bwboundaries(). Write back if you can't figure it out.
