Re: OpenCV (v2)
Hello JHPJHP,
that looks very interesting.
Unfortunately, I'm not able to run any of the examples (using PB 5.21 LTS on Windows XP x86).
I always get a German error message which translates to something like

PureBasic_Compilation0.exe - Entry point not found

The procedure entry point "GetTickCount64" was not found in the DLL "KERNEL32.dll".
Re: OpenCV (v2)
Hi Little John,
AAT and myself have tested the examples using earlier versions of the OpenCV binaries and C Runtime files, and because of some adverse results I elected too remove them; hindsight being 20/20 - I'll add them back later in the day.
Let me know if the new binaries work for you.

Re: OpenCV (v2)
Hi, @JHP!
I have tried your examples, and they are getting better & better each time!
Remember that thread I posted earlier about adding sound to the video recording?
If you integrate THAT, I'm sure people will be ALL over it! =D
Thanks again for your contribution, and let me know when you're ready for me to perma-host this project!

Mythros

Re: OpenCV (v2)
Yes! It happened! 
Thanks, JHPJHP!
P.S. I found a solution to the problem about which you wrote (#CV_CAP_PROP_FRAME_HEIGHT - returns 0 (XP only)).
Edited.
Background:
1 . you can't use OpenCV libraries compiled with VC11 in WindowsXP because they use function calls missing in WindowsXP (for example, GetTickCount64);
2 . you have to use the OpenCV libraries compiled with VC10 (VC9) for WindowsXP, they can also be used Windows7 (Vista);
3 . when using OpenCV libraries compiled with VC10 (VC9), some OpenCV functions work incorrectly, for example
cvGetCaptureProperty(*capture, #CV_CAP_PROP_FRAME_HEIGHT)
always returns 1 regardless of an Windows version (XP...7).
The problem has a very simple solution requires a complete and accurate prototyping functions OpenCV.
I specified type of returned value in a prototype of the cvGetCaptureProperty function and it returned correct value instead of 1.
I edited the file opencv.pbi:
- constants are added
- types of returned values are added in prototypes of functions (where I could)
- comments in prototypes of functions are added
Please check my additions.

Thanks AAT... I can respect the amount of time it probably took to figure out that it was the return value causing the problem. The last time we talked you were "Walking the DLL" trying to determine the differences between versions.
You probably didn't notice - I had updated the project prior to your post, modifying Structures & Data Types. The project has again been updated too only include your changes that now apply (including the extensive Constants list and cvGetCaptureProperty fix under XP), as well as a few additions I've made.
- because it was the same day I started this thread, I only mentioned the update in my original post, in future I will additionally create a new post, notifying that there has been a change
My updates stem from testing in PureBasic x64, and something I should have realized from other projects when converting from C to PureBasic... Int in C needs to be converted to a Long in PureBasic (unless otherwise specified); an Int is 4 bytes under x86 but 8 bytes under x64 - throwing off Structure alignment.
- as there is still a problem with OpenCV working under PureBasic x64, there will probably be additional changes to the IplImage Structure
Cheers - and nice work!

Re: OpenCV (v2)
Examples works fine in WindowsXP with libraries compiled with VC10.
Some troubles exist in functions
- cvWarpAffine(*resize, *rotate, *map_matrix, #CV_INTER_MAX + #CV_WARP_FILL_OUTLIERS, 0, 0, 0, 0)
with parameter #CV_INTER_MAX (cv_rotate examples) - i have a message "Microsoft Visual C++ Runtime Library Runtime Error! This application has requested the Runtime to terminate it in an unusual way."
- cvSobel(*resize, *resize, 0, 3, 3)
with third derivatives - i have the same Runtime Error.
I try to prototype function cvAdaptiveThreshold. It works!
Addition to cv_functions.pbi
Additions to cv_constants.pbi
Replacement in cv_threshold.pb

#CV_ADAPTIVE_THRESH_GAUSSIAN_C = 1
Code: Select all
; threshold.d = cvThreshold(*edges, *edges, 50, 255, #CV_THRESH_BINARY); + #CV_THRESH_OTSU)
cvAdaptiveThreshold(*edges, *edges, 255, #CV_ADAPTIVE_THRESH_GAUSSIAN_C, #CV_THRESH_BINARY_INV, 3, 8) Re: OpenCV (v2)
Tested cvWarpAffine & cvSobel examples with Windows XP, but I didn't receive an error.
- try substituting the C Runtime files you're using with the ones located in \binaries\cRt (v11)
-- msvcp110.dll, msvcr110.dll
cvAdaptiveThreshold has been added as its own example; the two Threshold functions offer very different effects
- constants added to cv_constants.pbi
I've also made some minor changes and additions - the most significant being the cvMat Structure.
Cheers!

Re: OpenCV (v2)
Hi JHPJHP,
I can confirm that it works now here on Windows XP 32 bit.
Many thanks for all your work!

Re: OpenCV (v2)
Great to hear Little John.
----------------------------
A new example has been added: cv_border.pb, including some additional Constants.
- also applied the border effect to: cv_canny.pb

Re: OpenCV (v2)
There's GOT to be a way to get the video onto a 3D texture and turn on / off sound.
Re: OpenCV (v2)
Hi Mythros,
Please try the Coding Questions forum, this thread is to demonstrate OpenCV compatibility with PureBasic, and I'd like to keep it on point. While audio can be added to OpenCV video, it's not inherent and would deviate from that purpose.
Thanks.

Re: OpenCV (v2)
Added a few new functions and another example: cv_filter2d.pb
- this filter appears to make images more clear / crisp
NB*: Most of the image examples are set with a high filter setting to emphasize the effect, not really the recommended use. For some of the examples, there are calculations (not included) that precede the function to optimize the effect. A trackbar could also be added to most of the examples to demonstrate the effect better: cv_flip.pb & cv_rotate2.pb shows how this can be done.
I've opted to create separate examples as opposed to combining them, to assist anyone else interested in this topic, by keeping things simple but functional.
Cheers!

Re: OpenCV (v2)
Renamed some examples.
- if an example uses the same (main) functions as another example, but produces different results, the name is appended with _1a, _1b, etc.
- if an example is designed to produce similar results as another example, but uses different functions, the name is appended with _2, _3, etc.
Added an extensive list of Constants, a few Functions, and 2 examples.
- cv_distance.pb
-- utilizes the new functions
- cv_threshold_1b.pb
-- a color version of cv_threshold_1a.pb (formally named cv_threshold1.pb)
Cheers!
