In VB.net 2005 what is the quickest way to read through an image? I currently have a class taking images from my webcam then it processes them and does stuff with them.(sort of like filters) I'd like for them to move a little smoother...

Is there a quicker way to go through an image than to just go pixel by pixel? While still keeping quality? Because I know I can make it go average of every 10 pixel but the webcam images are bad enough quality I don't need that making it worse...

Is there any other way?

Thanks,
Alex
