Color Coherence Vector in C#

Question

A friend and I are about to embark on creating a machine that performs some image comparison for sorting. I know about histogram comparison and am generally confident that a small grid of histograms per image precalculated and stored in columns in a database table will generally give us pretty good matches on the first pass because we are matching like things.

The second comparison we want to perform is to use a color coherence vector (CCV) of images which passed the histogram match test from our subject image to the candidate images. I know that this sort of comparison is more precise.

My friend is confident that he can develop CCV in C# using the C# wrapper to OpenCV. I am pretty sure he can too. However I would like to know:

1. Has anyone already done this in C# and released the source code? Or a C# wrapper?
2. Are we barking up the wrong tree? (Should we just use CCV and forgo histogram comparisons at the database level? Or is CCV too much?)

Answer 1

The OpenCV site mentions compatibility with VB, so I wouldn't be surprised if it exposes a COM interface. If so, just add a reference to it and let Visual Studio build the PIA (the wrapper) for you.

Unfortunately, I don't know the details of the image processing algorithms you mention, so I can't offer advice on your second question.

Answer 2

Hi all! Could you post the source code of the CCV implementation using OpenCV?
