thank you !

I want to load the trained model using opencv C++. My goal is to migrate from python to solely cpp platform

How to load a Keras model build with tensorflow backend in OpenCV Disclaimer, I posted the same question here and on St

Is there a limitation for cv::dnn::ConvolutionLayer dimension? I want to know is there a limitation for convolution laye

Yes, you can redefine cv::Mat allocator !!! Simple inherent from MatAllocator Implement the virtual functions needed

No, you can do it, Simple inherent from MatAllocator Implement the virtual functions needed Create a singleton in

The return type should be

double       mean_pxl = mean.val[0];
double       stddev_pxl = stddev.val[0];

otherwise you can use "auto"

auto mean_pxl = mean.val[0];
auto stddev_pxl = stddev.val[0];

Hey

I'm trying to build Opencv 3.1.0 on a stand alone computer (there is no internet access)

I have an Intel composer 2015 installed, which include IPP v8.

During CMake build configuration, I get the following message:

Cmake error at 3rdparty/downloader.cmake.73

for file: [..... /ippicv_windows_20151201.zip]

expected hash [...] actual hash [...]

I figure out that I need to manually download ippicv_windows_20151201.zip and place it in the sources sub - folder.

Do you know where I can download it from?

I can exclude the build flag: "WITH_IPP" , In that case, I'd not build with IPP at all, which is something I don't want.

I'd rather like to build OpenCV with my pre-installed IPP (Intel Composer), not the downloaded free version from OpenCV, Do you know how I can do that ?

BWT, What is the difference between build WITH_IPP and WITH_IPP_A flags ?

Best

I'd like to write an xml file using opencv FileStorage object.

Most of the examples I get to see works like the following

    FileStorage fs("d:\\1.xml" , FileStorage::WRITE); 
    fs << "one" << 1;

I'd like to write a section with modified name variable , which means that the text would not have to be inserted in compile time. I look for something like this:

    string st = "1"; 
    fs << st.c_str() << 1;

However I keep on getting run time error. it's refused to work, I have tried using opencv string type, stl string type , char* , but still can't make it work.

Any help would be very appreciated
