As advised by Bogdan Galineceu you can try PyNcvLib it works perfectly if you download files on my site !
But I don't success to change PyMelib (but Nokia provide only one example for this library

I've downloaded files from here: http://research.nokia.com/research/p.../download.html

But I gets the same error running example. Any idea? Thanks

Hey,

Sorry for the re-post, dont know if anyone is still watching the other thread anymore.

I have been trying the python bindings out and I am trying to use the edge detection function within ImageOperation.py like this:

-----------------------------------------------

sourceImg = PyNcvLib.PyCNokiaCVImage()
targetImg = PyNcvLib.PyCNokiaCVImage()
imgOps = PyNcvLib.PyCImageOperations()

inputImg = None
outputImg = None

inputImg = sourceImg.NewLC()
sourceImg.CreateL('e:\\testImage.jpg')

outputImg = targetImg.NewLC()
size = sourceImg.Size()
mode = sourceImg.DisplayMode()
targetImg.CreateL(size[0], size[1], mode)
outBitmap = targetImg.Bitmap()
outImg = Image.from_cfbsbitmap(outBitmap)

imgOps.EdgeDetect(inputImg, outputImg, 1)

canvas.blit(outImg)

-----------------------------------------------

Running this code results in a good output image which has the edges extracted but when I exit the application i get the following error:

"E32USER-CBase 71"

So I think that something is not being pop'd off the CleanupStack, but I don't know what. Any Ideas?

Thanks.

Found a Solution for the problem, I had been running the code fragment above inside a function, but for it to run without errors you need to place the following outside the function as declarations:

------------------------------------------

sourceImg = PyNcvLib.PyCNokiaCVImage()
targetImg = PyNcvLib.PyCNokiaCVImage()
imgOps = PyNcvLib.PyCImageOperations()

inputImg = sourceImg.NewLC()
outputImg = targetImg.NewLC()

------------------------------------------

Basically put calls to NewLC() in the main body of your script and it seems to run fine :-)

Cheers guys.

So, where can I download fixed libs? Does demo works yet? Thanks

Hello Yingen_Xiong

I have downloaded and installed new version 1.2 but at the installation it is displayed 1.00 instead of 1.2

How to use flash control in this version
I find FlashOn and FlashOff function only but no SetFlash() function

Is it possible to release C++ source code now ?
