question for Christian Grauss
-
Hi Christian, Need your help. I am going through your filter implementation articles. But i want to know how can i test if it gives correct result or not . And also i have implemented FFT of an image but i am not sure if it is giving me correct result. So please let me know how can i test it to make sure it is giving me correct result and also for inverse FFT. Thankyou :)

I suppose it didn't occur to you to try posting this question on the forum for one of his articles? No, I suppose not. That would be expecting to much. Marc

My point exactly. With all those words and junk in the way how are you expected to find what you're after? And don't tell me the answer is reading. I tried that once... not doing that again. Everything on teh interweb should only be 2 mouse clicks away from either the answer or boobs. If boobs are the answer it makes things that much easier.

If he'd actually read the articles, he probably would have known how to spell CG's name. It's nothing short of a miracle that he actually managed to post his question on the right site. :rolleyes:
But who is the king of all of these folks?

That's what I was thinking. I've seen how Christian gets when someone misspells his name....I pity the poor fool... :)

Why can no-one spell my name ? I've not done a fast fourier transform for hte library, I kept meaning to.... Really, the forum under my article is the place to ask me questions. Sorry if you did that and didn't get a reply, I am just now getting set up again for email notifications, I do go through my articles from time to time and look for questions that got lost. The short answer is, if you like the way it looks, the filters work. They do what they claim to do, but I'm not saying they are the best examples of the filters in question, they are meant to provide a framework for learning more than anything.

I once had a client who constantly complained that the software was too complex. I want one button, just one button, I know what I want to do, why can't the bloody computer Just give me a system with one freakin button. From that day onwards whenever he logs on he gets a big red button that fills 90% of the screen. It may even still be there as the app was written in 98 and is still in use and is supported by a friend.

Thanks for your reply. And sorry for extra 's'. Actually i agree with you that what you did gives the result but while you were developing those filters you must have tested them to be sure that you are getting what you want. So that is what i am looking for. If say i implement mean removal filter what proof i can give to the third party if they ask me prove it what i did is correct. What testing approach is used for it etc etc. I can't simply implement it and say what i did is correct. You know what i mean. Sorry for posting here. I will be careful from next time. Thank you

The approach I used for testing noise removal filters was that I added other filters that add noise, and made sure it was removed :-) The article covers that. I did use those filters in my own projects, they work just fine, but some of the more experimental ones are of dubious usefulness. There is another excellent image processing article on CP, it covers a lot in one article, with less explanation than my series. You may want to look for it and compare results between the two. His may well work better than mine, I have never looked.
