@blue_jay52413:matrix.orgblue_jay52413Hello does anyone know the best way to deskew an image for pre-processing before going into the ocr? I was translating this c++ code but came to a hiccup, where I can't convert a list<Point> to IntPtr. https://github.com/shimat/opencvsharp/issues/491 Any help? Otherwise is there already some inbuilt de-skewing or known code, as I cannot find anything. I've been trying to make a de-skewer for 2 days now.02:00:11

@sinaasefi:matrix.orgsinaasefiHi I'm working with OpenCvSharp4.4.3.0 but when I want to use from MatOfFloat it shows this error 'MatOfFloat' is not defined Do I need to import something else also? Thank you19:56:04

I think there's a homography transform

@skumarvenkat:matrix.orgskumarvenkathello , I need help pls, how to implement following sample https://www.pyimagesearch.com/2014/09/01/build-kick-ass-mobile-document-scanner-just-5-minutes/ using opencvsharp?10:18:14
@joreg:matrix.orgiorec skumarvenkat: well, the article explains it quite detailed. you'll only have to find the equivalent APIs in opencvsharp that are usually quite similar in naming. i suggest you start a program yourself and then come back with more specific questions.. 10:23:35
@skumarvenkat:matrix.orgskumarvenkatthanks for quick rely, how I get image = cv2.imread(args["image"]) ratio = image.shape[0] / 500.010:32:43
@skumarvenkat:matrix.orgskumarvenkatMat src = New Mat("Image path"); scr.Shapes[0]// not able to find10:33:37
@joreg:matrix.orgiorechave you seen these samples?10:48:08
@joreg:matrix.orgiorechttps://github.com/shimat/opencvsharp_samples/tree/master/SamplesCS/Samples10:48:12
@joreg:matrix.orgiorecI'm sure you'll find your answer there.10:48:30

@craftino:matrix.orgcraftinohi guys, I need help with "The type initializer for 'OpenCvSharp.NativeMethods' threw an exception". I believe I;m missing something in installation. I guess I need some other dll that' I am missing, is that correct?23:30:25

@catachan:matrix.orgcatachan joined the room.18:40:41
@catachan:matrix.orgcatachanSo, in C#, Cv2.Norm() won't accept a List<double>, but the C++ version is supposed to accept a vector<double>, does anyone have any advice for how to get around this?18:42:13
@catachan:matrix.orgcatachanI'm essentially attempting to translate the "digits.cpp" example from OpenCV into C#, and I'm stuck on translating the preprocess_hog() method.18:48:09

@stevenshih:matrix.orgstevenshihHi, I'm trying to build a project for detecting face in image on xamarin forms. However, when I try to read the image into Mat "mat = Cv2.ImRead(path, ImreadModes.AnyColor);". I got an error when running on Android emulator. Says "System.DllNotFoundException: 'OpenCvSharpExtern assembly:<unknown assembly> type:<unknown type> member:(null)' ". Does anyone know how to fix it? Thanks.08:13:12

I think, I have a similar problem. I have opened an issue at https://github.com/shimat/opencvsharp/issues/1009 .
