How do I compare two images & recognize the pattern in an image irrespective of its size and pattern size, and using .Net C#? Also, which algorithms are used for doing so from Image Processing?

I'm interested in learning about, and writing a system that will extract features from audio files (mp3, wav, etc) which can later be used for whatever purpose. In the future I hope to use it to write some software for music similarity.
Are there any libraries that exist to help? I know of libxtract, but haven't used it.
Also, are ...
Given the 2D contour of a shape in the form of lines and vertices, how can I Extract Information from that?
like: Pointy, round, straight line.
Shape similarities with a given shape.
Code is not necessary, I am more interested in
concepts and the names of techniques involved to
guide my search....
Thanks in advance.

Does anyone know of a (purely) matlab implementation of Haar feature extraction (the kind used in Viola&Jones object detection algorithm)?
(I ran across a matlab binding to Opencv's implementation but this is not what I am looking for)

Dear all,
I am on a project where I am interested in the spacing & distribution of
point objects in an microscope image.
So the image consists of darker, circular small dots from a rather complex background. It would be nice to do this with an feature extraction script automatically some day, but for now I am just hand-picking the poi...
Hi,
I would like to know if there is a good way for indexing multidimensional objects (i.e. images). More precisely, I have a large collection of images on which I calculate n-dimensional feature vectors. There is a distance metric (i.e. L2-norm) defined over those feature vectors d(u,v). Given a key (an n-dimensional) k, the index shou...
