Your images should be the same resolution as you will be using for the "production" system. Depending on your needs you may wish to experiment with a variety of resolutions and observe your accuracy as you vary the resolution.

ok, is it feasible though to use say my sony xperia go to capture all my training images and afterwardly test your model using a webcam (in real time)/ any other device?

[Walter Roberson]

Yes. Just make sure that you have at least two different resolution of images when you are doing the programming, as otherwise you are likely finding yourself programming to match one particular resolution.

Make sure to make your algorithm robust enough to handle different image sizes. for example, often window sizes that work nicely to filter a small image will have not much effect on a much larger image so the window filter widths may need to adapt to the size of the image.
