Search a specific folder for an image that is found within a picture

Been trying Google for a while and haven't even found a start point for this problem.

I am looking for a starting point for developing a check in system. I have a large database of images of inventory in house. Very clean digital HD images with no background or anything. I am looking to do a local image search.

I will have a small temp folder with only the images of products in the current order. Then to verify that the item in employees hand is that same, I want to scan the item in real time and compare it to the images in the folder. and work from there.

I can't seem to find any documentation on any classes that can help me with this functionality.

For example say I have an image on my PC, and I print out that image to paper in a VERY high quality. I want to then be able to match the print out to the original file.

Is there anything built into .Net for this?

I have done something similar in the past. But in my case it was a facial recognition system. It worked pretty well but you have to remember that it might not work in 100% of the cases. Visual recognition is a very complicated subject and we have yet to develop a way to have a flexible 100% accuracy system.

As to how I did it, I developped a NN(Neural Network) algorithm. This algorithm had to be trained against a specific set of pictures.

Another popular approach is to use a SVM(Support Vector Machine) algorithm instead of a neural network. Then again, you will most likely not get a result that is 100% accurate.

Keep in mind that there are many different algorithms that can be used to do visual recognition. Two other popular algorithms for facial recognition are Eigenfaces and Fisherfaces.

Sadly, I have not worked with those kind of project in .Net. But you might want to check for a third party NN or SVM library for .Net.

Here is a link to a SO thread about NN Open-source .NET neural network library?
