image comparison and retrieval of images

I am developing a project with c# in visual studio 2010 and i need some idea to related my project and my question is..........I want to match one image with folder of multiple images in that image matching technique i want to retrieve all the differed images from that folder of images which is to be not matched with that one image.......

The details depend on the comparison factors you want to use when comparing the images.
For example, do you want to compare the images based on specific objects in the image?

Do you want to compare them based on the colors count, intensity and colors distribution (how many times each intensity level occurs in an image)?

In all cases, you might be able doing this by using one of the following approaches:
1. Read the images data pixel-by-pixel and compare the pixel's color with your color. This is going to be slow, especially of the last pixel is the color you are looking for.
2. You can use LEADTOOLS Imaging SDK, which provides image processing classes like CorrelationCommand class, HistogramCommand class, etc. that can help you to compare your images based on the comparison conditions you want to use. For more information, see the following links:

3. If all images are paletized (contains palette), then you might be able create a custom solution to search the image's palettes without loading them.
