| vshmidt | Hi! First thanks you guys for a greate work with opencvsharp!!! | 14:23:28 |
| vshmidt | Maybe you have some time for a help with VideoCapture performance. I stuck into same problem with low FPS on Read method https://github.com/opencv/opencv/issues/9084. I have tried to solve it with setting Exposure/Fps/FourCC and etc but with no luck. My Read performance with Logitech 920 camera is only 15 frames per second. Much of time (about 60ms) takes Retrieve (RetrieveMat) method. Can not understand what can be a problem but Python code is reading cemera frames with ~30 fps on a same environment. I have splitted out Read to Grab and Retrieve to separate thread and introduce two threads for a Retrieve. This gives about 30 fps but it looks like a hack. Maybe you have some information about? How to increase Read FPS to number more than 15 frames? | 14:31:10 |

 iorec | vshmidt: sorry for late. have to say we cannot take any credit for opencvsharp and i'm afraid i believe its creator shimat hasn't joined here yet. | 11:08:19 |
| iorec | also regarding your question i'm afraid i cannot help. | 11:08:42 |

| swainjk | Does anyone know where I can obtain a version of OpenCvSharp that will run under x86 CPU? I have some other controls that are only available in x86. I found that the vreions I have been able to find runs under Any CPU, but does not when configuring for x86. | 02:59:43 |

| blue_jay52413 | Hello 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 | Hi
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 you | 19:56:04 |

| skumarvenkat | hello , 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 |
| iorec | 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 | thanks for quick rely, how I get image = cv2.imread(args["image"])
ratio = image.shape[0] / 500.0 | 10:32:43 |
| skumarvenkat | Mat src = New Mat("Image path"); scr.Shapes[0]// not able to find | 10:33:37 |
