Does anyone has code examples reading hdf5 files in F#? I cannot find any examples on SO or google. I tried hdf5.net library but could not get it to work using Python example code.
While I haven't tried it, there is some sample code available at https://rodhern.wordpress.com/2013/02/17/hdf5-f-to-octave-example/
It's the only example I know of offhand.

Is there any preferred way to deal with hdf5 files from polars? I cannot find any mention of them in the documentation. Polars seems like a wonderful library, but this is a major issue for me.
I have trouble to find the RANSAC (findHomography() in calib3d.hpp) sourcecode file (.cpp) in the opencv folder. Does anyone know where the source code is?
Is there in common and easy way to determine where the source code of a specific function in the OpenCV folder is? or do i need to look trough every file?
Here is the source code for the function findHomography() - https://github.com/opencv/opencv/blob/master/modules/calib3d/src/fundam.cpp#L319
Q:

a specific function in the OpenCV folder is? or do i need to look
trough every file?
A:
Google is an extremely powerful tool, I tend to just Google the function I am looking for followed by "opencv github", if I can't find it by doing that I crawl through the source code.
A bit of a general question, but what is the most popular/common/easiest way of creating a custom pcore?
I have seen some examples and they were mostly done on Matlab and since I do not have Matlab anywhere, I am a bit lost here. There has got to be a proper way of doing without it!
Thank you in advance!!!
You can create it with VHDL or Verilog languages, but after that you need to make few files like .mdp and .pao, create directory move all the files there and then put the directory to a library.
Detailed information you can find in Xilinx Manual
So, I want to obfuscate my lua code. I search for lua obfuscators on google and this site comes http://www.capprime.com/CapprimeLuaObfuscator/CapprimeLuaObfuscator.aspx. Also, I've seen many other site mention it too as a good obfuscator. But when I copy and paste my code to see that... the exact same code is generated. Why is that so? You can also test this by giving a sample input, that same output is generated. Are any good obfuscators around behind this? Thanks
As far as i know there are no obfuscators for Lua due to the fact that Lua allows you to implement your own obfuscator. Please read the C api of Lua and there you have ways of implementing your own file reader for lua files. By using that approach you can obfuscate/encrypt/decrypt on load of the file.
I am new to opencv and I am using opencv for windows. How can I see the source code for a specific function of an opencv library ? I just one want to get an idea of how that specific machine vision algorithm is implemented.
You can get the OpenCV source code from https://github.com/opencv. An easy way to find the header for a function is to open an explorer window in OPENCV_HOME\build\include (where is the location where you chose to install OpenCV) and use the search box to find the header file that contains your function - this will help you know what module it is in. Then you can search in OPENCV_HOME\modules\MODULE_NAME\src to find the source of the the function. This is even easier if you install a search tool like grepWin.
Looking at the source is almost essential for finding out why those pesky OpenCV exceptions are thrown. It also means that you can answer most things about OpenCV yourself without having to ask here.
Here is a direct link to an excellent source code search, courtesy of Github. This is a very straightforward way to find the implementation and internal usages of a function or type.
All the source is now on github:
https://github.com/opencv/opencv and you can use it's search functionalities as well.
I found the answer by Drew Noakes to be the most helpful, especially given the fact that repository structures keep changing over time.
To search in the code or in other places inside a repository using a keyword, the instructions here can be followed.
What would be even easier for first-timers however, would be to simply search for a key word in the github search bar. Then the appropriate advanced search option would generate the tags described in the the earlier linked tutorial.
