I am currently a graduate student in Computer Science and I have
just completed a course in image processing. I have also recently
purchased a digital camera which produces images in JPEG. I am looking
for a library that I can use to write C++ programs to manipulate the
image.
Does anybody know of such a library? I thank the group in advance
for their responses.

Perhaps something useful in: http://homepages.borland.com/efg2lab/Library/ImageProcessing/SoftwarePackages.htm You mention JPEG; surely that is irrelevant. You merely need to read the JPEG file into some 'raw' representation in memory -- where the image can be processed. It /could/ be that you would want to do processing in a 'JPEG domain', but it's hardly likely in the general. Incidentally, if I was intending on capturing images for 'processing', I'd try to store the images in 'raw' format. On the other hand, the raw image files I recently received from a (Minolta) digital camera were far from the simple (simply specified) byte collections that I expected; in the end, not having time to decode a rather complicated specification, I had to use a canned program to convert the files to TIF -- from which I could get to 'raw'; thus defeating the whole purpose of using 'raw'!

Hello Robert, The standard way to manipulate digital pictures is via Photoshop. Many authors have written plugins for doing their own kinds of adjustments. A neat set of code modules was written by Helmut Dersch. They are called Panorama Tools, but they do a lot more than that. You can warp, shift, skew, fourier filter, etc the images on each of the color channels separately. I use this to correct barrel/pincushin distortion and at the same time fix chromatic aberation. A neat thing about Helmut's software tools is he offers them for free and the source code is included. So you may be able to work from there.

Clay, Robert doesn't so much want to improve his pictures as to get experience writing code to process images in various ways. Photoshop or something similar probably came with his camera anyway.

Hi Robert,> a library that I can use to write C++ programsIf you mean "a library containing implementations of popular image processing algorithms", then googling on "c++ image processing library" gets a bazillion hits. If you mean "a GUI toolkit for writing c++ programs", I highly recommend WxWindows (www.wxwindows.org). Turn to Google. Google knows everything. Google is your friend.

It is about $700 US these days. If you can deal with a reduced capability, Photoshop LE works reasonably well. It is only a couple of hundred dollars. Most of what is left out is the stuff for advanced printing and color management. But if he wants to play with images, the bitmap format is probably the simplest to work with, and a simple paint program can be used as a viewer. I remember doing some computer generated holograms with bitmaps.
