问题 Edit: im now using http://code.google.com/p/jpeg-compressor/ so i dont care about making this work anymore. I downloaded the http://ijg.org/ source code, i tried to build it as a DLL file. This is farthest i could build until i went into dead-end. I noticed there was some .c files which i had to delete, but i dont know if i deleted the correct ones, there was at least these files jmemmac.c and jmemdos.c which i figured i dont need. I had to delete jmemmac.c because i compile on windows, but

问题 I'm trying to setup a simple OpenCV project using Microsoft Visual Studio 2008 in a 64-bit Windows 7 system. I don't have admin rights to the system and as such, I can't go for a fresh installation of OpenCV here. However, I do have the bin, include and lib directories of OpenCV, compiled on a simillar platform. I have launched a 'Visual C++ -> General -> Empty Project' and created a .cpp file which reads: #include <opencv/cv.h> #include <opencv/highgui.h> void main() { cv::Mat frame = cv:

问题 everyone.! I am using opencv2.4.2. actually I am doing project on object detection. I tried using BackgroundSubtractorMOG model. But I am not able to load video file from my computer. While running on real time this below code for segmentation works fine. I have implemented using frame differencing method for object detection. Now I want to segment whole object from the background. I have static background. so can anybody help me in below code how to segment object from captured video. also

问题 Can we define the variable in c++/ c using special characters such as; double ε,µ,β,ϰ; If yes, how can this be achieved? 回答1: As per the working draft of CPP standard (N4713), 5.10 Identifiers [lex.name] ... An identifier is an arbitrarily long sequence of letters and digits. Each universal-character-name in an identifier shall designate a character whose encoding in ISO 10646 falls into one of the ranges specified in Table 2. The initial element shall not be a universal-character-name

问题 I am just trying to compile a bit bigger project using the Visual Studio 2012 Release Candidate, C++. The project was/is compiled using the VS2010 now. (I am just greedy to get the C++11 things, so I tried. :) Apart of things that I can explain by myself, the project uses the code like this: ostringstream ostr; ostr << "The " __FUNCTION__ "() failed to malloc(" << i << ")."; throw bad_alloc(ostr.str().c_str()); The compiler now complains error C2248: 'std::bad_alloc::bad_alloc' : cannot

问题 I am using MSVS 2006 and trying to find time in microseconds in my program. I try to call sys/time.h in the header but this error is compiled. fatal error C1083: Cannot open include file: 'sys/time.h': No such file or directory Error executing cl.exe. and this is my code, #include<sys/time.h> #include<stdio.h> int main() { struc timeval stop,start; gettimeofday(&start,NULL); /*my function here*/ gettimeofday(&stop,NULL); printf("took %lu usec\n",stop.tv_usec-start.tv_usec); } 回答1:

问题 I'm trying to make a great GUI for my csgo cheat. I decided to use C++/CLR. Firstly I create empty project then, I change in a properties entrypoint and the subsystem and I add this code to the cpp file: #include "MyForm.h" using namespace System;` using namespace System::Windows::Forms;` [STAThreadAttribute] void Main(array<System::String ^> ^args) { Application::EnableVisualStyles(); Application::SetCompatibleTextRenderingDefault(false); SmallPackofCheats::MyForm mainForm; Application::Run(

问题 What exactly is going on inside this Win32 messaging loop? I understand that TranslateMessage is converting keycodes to UTF char codes and sending the WM_CHAR event, but what is the call to PeekMessage doing exactly? Is it filtering out a certain type of message and only translating those? // Application / Player message loop. MSG msg; ZeroMemory(&msg, sizeof(msg)); while(msg.message != WM_QUIT) { if (PeekMessage(&msg, NULL, 0U, 0U, PM_REMOVE)) { TranslateMessage(&msg); DispatchMessage(&msg);

问题 I created a cross platform OpenGLES application solution on Visual Studio. I paired Visual Studio with vcremote on my Mac. I can successfully compile the solution. When I switch to XCode and open the project which VS 2015 generated and build it I get the following error: Ld /Users/elodie/Library/Developer/Xcode/DerivedData/iOSAndroGame.iOS.Application-cgfyoibpjigxohbhicqhmkivhjhs/Build/Products/Debug-iphonesimulator/iOSAndroGame.app/iOSAndroGame normal x86_64 cd "/Users/elodie/vcremote/C
