Wooowww !!! again more impressive i imagine !!!
Perhaps it's again my fault
But i have found an error "incorrect number of parameter" in line 50 in cv_pbimage_1.pb and cv_pbimage_2.pb
Code: Select all
cvSave(xmlPath + xmlName + "_keypoints.xml", *keypoints, #NULL$, #NULL$, #Null)
Again thanks to your useful job

Hi, JHPJHP
JHPJHP wrote:...Some new functions have been REM'd out - there in the documentation, but not included in the DLL?...
I have found these functions in "core_c.h": they are "inline" functions.
I'll think over your new examples and will try comparison of contours.
Thank you!
Good luck!

You have to comment (remove) these lines:
Code: Select all
xmlPath.s = GetPathPart(FileName)
xmlName.s = GetFilePart(FileName, #PB_FileSystem_NoExtension)
cvSave(xmlPath + xmlName + "_keypoints.xml", *keypoints, #NULL$, #NULL$, #Null)
cvSave(xmlPath + xmlName + "_descriptors.xml", *descriptors, #NULL$, #NULL$, #Null)

Thanks AAT
Know you a simple way with OpenCV, for have the same result of this site using pHash lib, or it's too difficult ?
http://phash.org/demo/

Sorry, i'm not specialist in image processing.
I think there is no sense to try to achieve the results of phash.org with openCV, rather you have to write PB interface to this lib (if you want).

No no it's not my question
I just ask if it's possible, to do the same thing with OpenCV and the splendid work of JHPJHP, than what do the site of pHash..
So comparison of two picture, and say a percent of similarity, or a number of differences, etc..
In fact the same behaviour of the site, but with OpenCV
Perhaps begin with the "cv_contours_1.pb" ???
or perhaps "le_contours_6a"...
What is the better way ??

Look at \openCV\sources\samples the examples with keyword "features", or le_SURF.pb in JHPJHP examples.

Hi Kwaï chang caïne,
Thank you for pointing out the error in the two examples... they are now fixed.
---------------------------------
Hi AAT,
Thank you for the information concerning the inline functions - I will look into it.
Cheers!

Thanks AAT i regards this way

No no, it's me i thanks for this great job

Updated:
- added Constants, Structures, Macros, Inline Functions (converted to Procedures)
- added 1 example
-- cv_mov_text.pb: draws text to a movie file and saves it as an AVI (Audio Video Interleaved)
The new example was derived from the following post by normeus:

There is no progress with SVM and OCR. You can test code without recognition. Test pictures (from internet) on

Hi, i made a very plain OCR engine way back in 2008, and i picked it up again and it seems to be the perfect solution for this job.
Any interest?

Hi Philippe-felixer76-3. Yes, it is interesting. Is your OCR made with openCV and PureBasic?

It's purebasic only, i thought i lost it but then i scanned my external HD and found it again.
Im working on it to integrate it into your code.

Hi Philippe-felixer76-3,
Very interesting, your efforts are appreciated.
--------------------------------------
Updated
- added Constants, Functions, 1 Inline Function (converted to a Procedure)
- added 1 example (jointly contributed by AAT)
-- cv_approxpoly.pb: approximates a polygonal curve(s) with the specified precision
- added 1 default image
The example attempts to count the number of sides for each shape, illustrating the difference by outlining them in various colors. It's worth noting that cvApproxPoly is very precise, my fist attempt was to use an image download from the net, but the slightest imperfection in a line would count as another point, sometimes returning hundreds. I decided to create the image using MSPaint, even so - the arrows having 7 sides return 9 because of a slight variance to the contour.
--------------------------------------
Hi AAT,
The new example may be of some help with your current project. I don't think any one solution would suffice, but a combination of cvMatchShapes, cvApproxPoly, etc. with the OCR script Philippe-felixer76-3 is working on, may be enough to exact results.
Like I previously mentioned - cvApproxPoly is very precise, and may be able to narrow similar results to something useful.
Cheers!

I have been using OpenCV in BlitzMax and C++ for ages. Great to see your work here getting it working with purebasic.
I am getting POLINK errors using PB x64. I can see no x64 directory in the binaries directory.
Is this now only 32bit?
