Learn opencv Videos

You are brilliant Chris, very clear and detailed presentation!!I use openCV on a decaptcha .net project, but I did not train it with a set of reference char as u did, nor do I use KNN. I am using instead the inbuilt OPENCV Tesseract class along with its set of reference Tessdata files where the letter vectors are predefined. The code in vb is much more condensed and quite effective - I have around 50% success rate on 8 letters captcha after character isolation, rotation and formatting for which I developed code myself.The vb code is a such.''Dim myOcr as Tesseract = New Tesseract("","eng",OcrEngineMode.TesseractOnly,"0123456789")myOcr.Recognize(New Image(Of Bgr, Byte)(bitmap))Dim ocredChar as string = myOct.GetText"Have you been able to compare the merits of the 2 different approaches?All the best.

Hey I wanna ask you something I'm using same code but I cant figure out how to make detect "i" character. It just selecting "ı" part of it

@18F4550videos Thank you for the code.. Its working perfectly . Can you do one for character classification using SVM as well

Awesome, but too bad it doesn't work on VS2012 cause of this line : std::vector intValidChars = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9'; } I see on some forum that you can use this syntaxe only in VS2013. But nice tutorial ! thank you !

Please make more videos on PIC18F, you made those videos enjoyable for micro controller newbies like me. 

Hey phantom awesome it's good love your videos I don't always have time but your good guy and awesome seeing you have fun with games. You deserve more but sadly eh well I hope this year more fans and go luck 

YESSSS

Hi friends I watched all your wideos but l didnt finalized my projects first step l created GenerateData.cs and l controled my classifications.xml and ıts lıke that - AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA== and l control my images.xml file its llike that - AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA............AAAAAAAAAA I thınk thıs reasons my second steps TrainAndTest.cs dont work when l worked programe ıts select all number from ımage but "number read from image = " is emty dıdnt wrıte any number to my textbox please help me why l have like thıs problem ?

This Tutorial was really great! please create similar tutorial on other machine learning algorithms such as SVM etc.

When I run mine, it does not show those "BG intensity.....". Also, it does not create the edges, processed, and rejected images.

Hi, I've been following your tutorials, and when testing this one, it says "python: can't open file extract.py'. Maybe python is not compiled? How to do it?

The error ValueError: too many values to unpack shows that you use OpenCV 3.0, and findeContours has different syntax. to fix it change it to: img_ret, contours, hierarchy = cv2.findContours(edges.copy(), cv2.RETR_TREE, cv2.CHAIN_APPROX_NONE)

Hi, very nice presentation. Will it be possible to find pdf document of this presentation ? Best.

im doing a project regarding opencv im new to this area can anyone help me i can give money if want

for that people you have to use the target of the rifleor gun :D

Help Me!!! Have a error in this line: Core.rectangle(mRgba,facesArray[i].tl(),facesArray[i].br(),FACE_RECT_COLOR,3); the method rectangle(mat point point scalar) is undefined for the type core
