Click on images/buttons by compare to stored image file

Hello.

I have now been a rookie AutoIt programmer for about a month - and still learning.  

One aspect is to see what other can do; I was reading a little about the Sikuli project. It has some similarities with AutoIt, but in no way as mature and robust, but it has one feature I would like to replicate in my AutoIt scripts. It can find areas of the screen by compare stored image toward the desktop and find the similar area.   

Can I use a imagefile in AutoIt to do the same? 

In Sikuli it goes like this:

Find (screenarea1.png)
Click (screenarea1.png)

What happend is: Find an area in the screen that is exactly similar to "screenarea1.png". Mouse click the area.

Is there any way AutoIt can do this?
