2014-09-13 03:23:06 -0500 asked a question How to add pedestrian recognition feature to the library

I wanted to add a new feature to the openCV library . namely , the pedestrian re-identification method discussed here .

Where do i start?

i have gone through the coding style guide. i have forked the repo . and created a new branch.

which module should i add the feature to?

how much progress should i make before sending a PR ?

im a noob to contributions. sorry for any stupidity.

@ berak - i did do that.

and this is just for future reference... as i intend to go out on an adventure soon..

cant i do "git checkout master" and then make the opencv library again to change into the latest library.

or do i have to run sudo make uninstall from the build directory.

how do i find whats diff between the branches and what does master mean?

what is the response when you do the git clone?

i think


might solve it.

it did. thanks @berak ! :)

2014-07-22 11:04:17 -0500 commented answer cannot run compile opencv program

but it dint make a difference the newly installed file system still dint contain any file with imread declaration.

encountered the same error. if i do a git checkout what would happen? would opencv 2.4.9 based codes run on it?

2014-07-22 07:30:02 -0500 asked a question latest highgui.hpp missing imread declaration.

for installing opencv i pulled from git.

on running the simple display image program , i ran across the imread() cant be resolved error.

in older versions, i have seen imread declared in highgui.hpp

the present highgui.hpp i downloaded contains this:



include "opencv2/core.hpp"
