I have a picture that contains more obiecte.Obiectele I have separated into smaller pictures (cut from full size) must make a sequence of code that I find an object and make a circle around him. This subject had been opened 21 Dec 2011 as a 'identifying objects in a picture containing several objects'. I want to to know if we try to find same object in image more than one and different rotation how can we do? For example there is three same object in image with different places,also 2 of them vertical and last one horizontal. Can we identify with same method under 'identifying objects in a picture containing several objects' topic? Below 'img.jpg' original image and 'img2/3/4.jpg' objects which need to be founded. How can i find all objects same as img2/3/4?

As I understand this finds a one object. As you can see my image consists of many same object. I have one referance object and i want to find all objects which are same with referance object. For ex. as you can see third referance object are five peaces in original image(you can see right top region). While i am using one referance object, i want to find all 5 objects in a seperate 5 circles. Could I tell?

You can lower the threshold to find as many similar patterns as you want. The lower the threshold, the more additional regions it will detect, though the less similar the patterns will be.

Hi Ahmet, Have you tried 'ColorThresholder' app that can detect different regions of an image.
