| Object matching IMAGE 1: 2 objects IMAGE 2: 1 object Now I have worked out the position of the objects. How could i check in image2 whether any of the objects have been seen in image1? |

| Classify the objects in Image 1, and keep a time/pattern history of the objects seen.

| What do you mean by that? What pattern? and by time do you mean position? |

Keep track of the objects you have seen in Image 1 and the time they were seen. After a set time limit discard the records. For each object seen in Image 2, check the list of objects seen in Image 1 for matches.

| How would you use a histogram to compare objects? |

| Maybe you need associative memory, it is very cool, similar to "handwriten letter recognizing system" that I built...?

That depends on what data the histogram is mapping and how you want to compare the two. I wouldn't suggest a histogram for the problem you posted though, suggest a FIFO queue that keeps track of the objects seen in each picture over time. Keep separate lists for each picture, and compare the two lists to see if an object in picture 1 is latter seen in picture two, or if it was in picture 2 first.

| Yes, but with associative memory you could even compare two objects if they were rotated ^^, ANYTHING you want.

| You should really post some kind of warning when you include terrible images in your threads. Quzah.
