identify objects on given image

Hi,everyone.

I am new to image processing with matlab and recently I am working on identifying an object on a given picture.

What I am going to do is firstly using butterworth filter to sharpen the image. Then use average filter to remove noise. This works well actually. Finally use edge detection like sober or robert to get the image.

But I know these filters and operators are basic tool to deal with image. Are there any better choice for filters and operators? Are my steps to deal with image correct?

Thanks for your help!

Yes there are, needless to say, many, many more methods to do image processing and image segmentation than those. Which you use really depends on your image and what you want to measure in it. In fact, edge detection is rarely one of the steps. If you have some specific image in mind, then insert it with the green and brown frame icon.
