Getting Started whit IPPI, please I need some help

jimawary_lauril1 — Thu, 28 Apr 2005 16:07:46 GMT

Hi to all!

It is the first time that I use the library IPP.
Especially I am interested in the IPPI, for the processing of medical images.
I need some help, I understand that you will be very busy, but it is because I am lost.

I wanted to make a software of test, similar to the demo, to visualize and to try to implement the different filters and methods, and then choose the most adapted for the application of the images processing.
The principal problem that I have, is to visualizate the images in a MFC GUI, since on having changed after every function of format, they are in the habit of giving me problems of execution. :smileysad:

I would be grateful for you very much if you could send me something of code to guide.

I am interested in the application of filters, detection of edges and calculation histogram as well as itsvisualization.

Im using C++ and .NET

Thank you in advance.:smileyhappy:

Hi,

I recommend you to take a look on IPP samples, for example - ippiSample example demonstrates how to use IPP functions and shows results before and after applying IPP func on image. You can find all IPP samples here

http://www.intel.com/software/products/ipp/samples.htm

By the way, you may be interested to know, that IPP JPEGView sample support JPEG Lossless mode which is frequently used in medical applications.

Regards,

Vladimir

Thank you very much,
I have been working, trying to do an application of test similar to the "demo" that comes in the package of evaluation of the IPP.
Till now I have realized Gauss's filter, a Filter Max and RGB's conversion to scale of gray.
The conversion of color always works well, nevertheless when the image tries with other two functions often there gives me mistake of execution, especially, if it is the first processing that I realize in this execution.
Other times,it executes well a number of times until it gives me amistake again , what could be the problem?
It is that in occasionsit executes well and in others not.
It gives me mistake in the reading memory 0xC0000005,
That can cause this violation of segment?

Would it be possible to obtain part of the source code of the demo?
its because iI think that it isnt a problem of incompatibility either with the processor or with the images, because the demo, works well.

I expect to obtain sufficient level to be able to help othe users in the future.

Thank you for everything in advance.

Hi,

it is better to provide some simple example of using IPP functions. It seems for that you might be not care about borders when you are use IPP filters
