C# or Java ??

I took three courses in computer graphics as an undergraduate that used PL/I-80 (on a CP/M box, no less). Each graphics system had a whopping 256x192 resolution, with 256 colors per pixel (4 levels each of red, green, and blue). My final project in the third course demonstrated 3D hidden surface removal using binary space partitioning trees. BSP trees were used in the original DOOM for rendering the 3D environment :cool:.

This also proved that John Carmack is not God as was believed at the time. In the first level of the Shareware version the was a small piece of floor missing due the Binary Tree. As far as I know this was the first time recorded history that Mr Carmack was proven wrong in his design. ;P

So people are using VB for image processing nowdays? Fascinating.

And have done so for years, even in VB6. So what's your point? Was there even a point? In most applications speed simply doesn't matter that much. And although (reasonably fast) image processing in VB6 used to be more work than, say, in C++, this was often offset by the efford to interoperate with a C++-coded image processing DLL. So image processing in VB was (and is, even more so) a completely sane choice. Of course, if you have other requirements, e.g. process a large batch of images really, really fast, then scratch the above and turn to ASM. On the other hand, there are some excellent assembly-enhanced VB6 codes out there to do just that.

Ah - I managed to avoid COBOL. I have more of a mathematical background, so I was more on the FORTRAN, APL and C track.

Hi, I have got a new project which is based on image processing. Which language will be better for this project.. C# or Java and why ? cheers rNr

Funny you should ask as I have been developing image processor routines in C# for the past 2 weeks for OCR apps. Image manipulation is fairly easy once you are able to pull images into the correct binary classes, then I have been able to apply image transitions quite easily on a bit by bit level. Its not as fast as I would like but I have not optimised the code at all, it takes about 3 seconds to apply a brighten & sharpen filter on a 247k grayscale tiff. I am limited by the choice of language here though and have no idea on how fast java would perform.

You sure got a lot of stupid answers to that question. Anyway, I depends on what language you know best and especially how complex you app is going to be. If it's pretty advanced Java has a big advantage in that there's the JAI (Java Advanced Imaging) API, and AFAIK there's not really any equivalent API for C# (.NET) though I can be mistaken. Ergo: If you know C# really well, and you app is going to be mostly home-implemented algorithms use C#, otherwise if you are going to make a big image processing app, and want to take advantage of a very nicely build API use Java and JAI.

pure image processing, or GUI? what platform? cross platform? the best way (in my experience) is to separate the GUI application from the image processing logic. best image processing library support is in C++, then Java. C# comes last. easiest to GUI (at least in .NET) is probably C#. if you have serious image processing - C++ (and C) give you the best programmatic control, which C# and Java don't. (they are more elegant, but much "weaker"). hope i helped. good luck.

I'd definetely say C#. Not because of tha language itself but because of the tools that are provided for it. Visual Studio will make your life so much easier than working with Eclipse or NetBeans. And I love C#, so this probably isn`t an impartial opinion. Regards,

and what kind of image processing? some people have answered as if that explains everything. I see no explanation at all. Basic image processing (histogram, color shift, edge detect, etc.) or user defined image processing (advanced filtering, fractal edge detect, wavelet differencing), or even real-time image processing (image processing on live video, multi-frame blind convolution, image based object tracking). These are all image processing, but they conjure different levels of need as far as existing infrastructure in the language, and especially speed. Basic image processing is usually easy enough language is irrelevant, java has an image library you can use to help, C# can use existing dll based image libraries through the infamous pinvoke. The only question relevant is based on personnel, which do you know, which can be better supported by your staff?

why did you choose those languages? you could have chosen COBOL, or LOGO, or PL1. Are those the languages you know, the only ones you know, and you have to build this? Then perhaps, maybe this is the right question. Though if your requirements do include anything that will refer to speed, you may not be the right person for this project if that is all you know. I love the answer that skipped C++ and went straight to assembly if speed matters, by making absurd associations like that people try very hard to kill a language that refuses to die because it is still being used. All in all, you haven't given enough information to answer, anyone who says otherwise is basing their decision on their language preference only. what are your requirements? what does the user expect?

C++, then Java, then C#. That is just my two cents. Having developed in all three I think I have a solid foundation of the opinion as well.

It depends to you and your client,but my suggestion is C# and also c++ is good.

between the two C# but for image processing u should consider C++

would you mind providing empirical evidence to that extent? Having developed two 3D platforms in Java, I'm not convinced of all this slowness that people purport Java to have. Specifically, can you demonstrate what areas C# is faster in?

As noted, the best language is likely the one you are most familiar with. Some notes, Java comes with the JAI which is a library specifically designed for Image processing. There is also a very good Java Image Processing book. Unfortunately the book was released before the JAI library so does not take advantage of it. The book is, regardless, quite good. C# has image processing libraries available from third parties. As noted in this thread, if you want a GUI interface on top, Visual Studio provides a handy WYSIWYG GUI editor. I prefer hand coding these things, so Java works better for me there. C++ has many good third party image processing libraries available. As far as speed, I think you'll find Java comparable to C++ in most respects, and good benchmarking tests and tools will make this clearly evident. The one thing I would point out, though, is that Java has a very poor implementation for their trig library and it is VERY slow. This is the only thing that would give me pause to use Java for image processing.

Never tried Fortran. But did use PLAN on an ICL 1900 series, as well as COBOL and Assembler on an IBM 360. Those were the days when timeshare was common and input via a punched card/tape after agency punching them from 80 column hand written coding sheets.

He is probably just bloating the forum. I'd say that C# and Java perform very closely with some specific parts one is fast than the other, but nothing really significant. What is the fact is that both of them are outperformed by C++ and other unmanaged languages. Managed languages have many advantages, but some of them comes at the cost of performance like automatic garbage collection. I might be wrong but if I were to choose a language only for performance reasons I would have a hard time trying to decide on C# or JAVA. Maybe I would just flip coins.
