How do apps that change eye color work?

Question

iOS

How do apps that allow you to change eye color work?
I'm still new to MP development, and I want to understand how such an application can be implemented.
Let's take an app that allows you to change the color of a refrigerator as an example!
Where to start the implementation, and what parts does the implementation of such an application consist of?
PS: I want to start working with camera and photography...

Answer 1

it will be possible to change the color of the refrigerator!

It's far from the same.
Eyes are very easy to look for using libraries (the same opencv).
-Next, select the circle with the iris.
-Apply a color and saturation
filter to the circle -Apply a mask to the circle, which will make the transition to full transparency along the contour (say, 10 percent of the linear dimensions of the circle). This technique will hide the out-of-print tonality of the circle relative to the substrate.
- Overlay the circle on the original image.
However, you are unlikely to find ready-made libraries for detecting refrigerators in the photo.
