Help with design structure choice: Using classes or library of functions
- by roverred
So I have GUI Class that will call another class called ImageProcessor that contains a bunch functions that will perform image processing algorithms like edgeDetection, gaussianblur, contourfinding, contour map generations, etc. The GUI passes an image to ImageProcessor, which performs one of those algorithm on it and it returns the image back to the GUI to display. So essentially ImageProcessor is a library of independent image processing functions right now.
It is called in the GUI like so
Image image = ImageProcessor.EdgeDetection(oldImage);
Some of the algorithms procedures require many functions, and some can be done in a single function or even one line.
All these functions for the algorithms jam packed into ImageProcessor can be pretty messy, and ImageProcessor doesn't sound it should be a library. So I was thinking about making every algorithm be a class with a shared interface say IAlgorithm. Then I pass the IAlgorithm interface from the GUI to the ImageProcessor.
public interface IAlgorithm{
public Image Process();
}
public class ImageProcessor{
public Image Process(IAlgorithm TheAlgorithm){
return IAlgorithm.Process();
}
}
Calling in the GUI like so
Image image = ImageProcessor.Process(new EdgeDetection(oldImage));
I think it makes sense in an object point of view, but the problem is I'll end up with some classes that are just one function. What do you think is a better design, or are they both crap and you have a much better idea? Thanks!
