image processing program in C or C++

Hi, I am converting my matlab program into C/C++. I need to change some
image processing toolbox functions into C/C++, such as edge detection,
mathematical morphology.

Is there any place that I can download some open source program to
release my load?

Many Thanks

See http://www.parashift.com/c++-faq-lit....html#faq-37.9
for some links to libraries.

Probably not, but I would Google for [chaincode OCR open source]. That's
where such things are typically used. I think I got one of them working,
once.

When requesting a web search, always report your experiences with Google, so
we will know what you couldn't use.

Lti-Lib is a free library that has classes for both morphology and edge
detection (not sure how good). It can be found here:

openCV, as far as I know, can do many well known image processing
tasks. e.g. CANNY for edge detection. However, I dont think you want to
rewrite nearly all the codes...... Can I ask why you want to abandond
MATLAB?

I think Intel IPL is also free download. Not sure if it is opensource.
You can try OpenGL too. It may be a overkill but I am sure it has most
of image processing algorithms.
Anyway in my opinion, new MATLAB alogorithms are way more efficient
than their previous versions. (Signal processing toolbox for example).

Input? OpenGL strikes me as a driver for rendered output...

OpenGL does provide some capabilities that can be used to implement
image processing. For example, some forms of edge detection are pretty
easy to implement.

One good point is that such an implementation tends to be quite fast
since it runs on dedicated graphics hardware (on a system that has it,
of course). The bad point is that unless you really need that speed or
are using OpenGL for other purposes, chances are this is going to be a
relatively difficult way to do the job. Along with coding the algorithm
itself, you have to learn all the OpenGL "stuff" that applies -- and
image processing is rarely (if ever) one of the first topics an OpenGL
book will cover either.

There are plenty of other places where such things are used besides
OCR.

Agreed.

Hye Friends!!, Happy New Year!! I am Jigar Mehta from India. Currently I am working on a project in which I need to compress some images on the harddisk... I want to make an engine that reads whole BMP image and then compress it.. The target location can be of any type.. BMP, TIFF, JPG or any.. Some data loss will be negligible because all the images are having very high resolution with 32-bit colors (taken from digi-cam).

Hi, I have an Access 2002 - 2003 database. I am using Access 2003. Whenever I link an image all it shows is the filename. Not the image. Other versions of Access can link the image just fine.

Hello all, I am currently implementing a fairly simple algorithm. It scans a grayscale image, and computes a pixel's new value as a function of its original value. Two passes are made, first horizontally and second vertically. The problem I have is that the vertical pass is 3 to 4 times slower than the horizontal, although the code is _exactly_ the same in both cases?! The code itself is very simple. There are 2 loops to scan through...
