Finding the location of a specific image inside a PictureBox with VB.NET

blinkor12 101

I have a PictureBox with a image inside it. Inside that image, there is a object placed inside it, which in this case is a 'Red X' in the following image (Just an example of what I mean):

I'm trying to find a way where I can search for the location of the Red 'X' (or any object) inside any given image and return the location of where the red x is located within the larger image with a (x, y) coordinate. I've seen several examples of searching whether the an image exists inside the PictureBox but not being able to output where it is.

Is there a way I can output where the location of the Red-X is of a PictureBox with not just searching for it?

I've attached the red-x image by itself here:

Hi @blinkor12 ,
How did you put the 'red-x' inside the image in picturebox? Could you provide some related code here? It will help us make a test.
We are waiting for your update.

But if the "Red X" is inside/over a red triangle, I don't see how you would find it (the standard methods are by comparing RGB for each pixel to detect a small image inside a bigger one)

@Castorix31 @Xingyu Zhao-MSFT Hi, I meant that the Red-X would NOT be in the triangles or overlaying anything but will always be by itself (Not hidden or covered or connected to a different object). I just put the colored triangles there to simulate my point that there WILL be other objects inside the picture with similar colors, not just the triangle itself since some people may comment that the solution for this problem would be to "look for the specific color in the image" or "look for something in the transparent image". Yes, the triangle will be all by itself so there shouldn't be a problem finding it :).
