I have a C++ module that I use with pybind11 to expose functionality in python. It all works nice, for example I am exposing classes, functions and enumerations from the C++ code, for example: py::class_<MapErrorMsg>(m, "MapErrorMsg") .def(py::init()) .def("SetFilename", &MapErrorMsg::SetFilename) .def("GetFilename", &MapErrorMsg::GetFilename) .def("SetWarnLevel", &MapErrorMsg::SetWarnLevel) .def("Warn", (void (MapErrorMsg::*)(MapErrorState, std::string, std::string)) &MapErrorMsg::Warn, "Warn with a level and two ..

I am working on a program under Visual Studio. C++ based program that has embedded python functions. When I call the python fuction it gives me back 4pcs of floats (pointers). I dispaly that on a textBox and send it to serial port (if arduino connected). I am doing this in a loop ( until ..
I want to use pyside2 to develop a pathological image recognition tool, but I don’t know how to display the whole slide image (the suffix is .svs), just like the function of ASAP software can quickly open and display images. Can someone give me some advice? Thank you very much! Source: Windows..
I am trying to return the current_time or current_time +1 in a func, where I am using the win10toast. My code was working fine before, it just suddenly stopped working. I didn’t do anything or change any settings. When running the following code: from datetime import datetime, timedelta from win10toast import ToastNotifier toast = ToastNotifier() ..
I´ve been trying to numerically calculate the inverse Laplace transforms of functions f(s) involving things like 1/(((a+s^2)^0.5)sinh(b*(a+s^2)^0.5)+cosh(c*(a+s^2)^0.5)). I tried zakian´s method on python, but got an overflow error. So, does anybody know of a program or code(preferably in Python or C++) I can use to find these(having the computational power of an average Laptop)? Source: ..
Consider this little pybind11 wrapper + test: setup.py from pybind11.setup_helpers import Pybind11Extension from pybind11.setup_helpers import build_ext from setuptools import setup setup( name="wrapper", ext_modules=[Pybind11Extension("wrapper", ["wrapper.cpp"])], cmdclass={"build_ext": build_ext}, ) wrapper.cpp #include <pybind11/pybind11.h> #include <pybind11/stl.h> #include <vector> namespace py = pybind11; struct Mesh2d { public: Mesh2d(int numVerts, int numTris) : numVertices(numVerts), numTriangles(numTris) { vertices = new float[numVerts * ..
I’m trying to replicate voice changer/modulation programs such as VoiceMod in any programming languages; Python, Java, C, etc. Looking to make it with as low latency as possible, and directly takes audio from microphone in real time and output to any user preferred program that involves microphone input. There’s very little resources and hope someone ..
Firstly, I opened the python file with notepad, and another day I right clicked the python file and opened it with python idle and from that day python files is not showing the python icon. which is not looking good. Can someone help me?? These are all python files Source: Windows..
I am confused about what Projection Matrix means. If I have one monocular camera, and I want to triangulate 3D points from image (2D) points of two consecutive frames I_k and I_{k-1}, and I use cv.triangulatePoints which need 2 projection matrix and 2 arrays of 2d points. So what confuses me is this: As far ..
I have many pictures of a chessboard with a smartphone to calibrate my camera for detecting markers. And then I calibrate my camera with OpenCV: cv::calibrateCamera(objectPoints, imagePoints, cv::Size(viewGray.rows, viewGray.cols), cameraMatrix, distCoeffs, rvecs, tvecs); I calibrate my webcam in my case. But if I want to calibrate an other camera, to do some tests (pose estimation ..
