I am working on a program which detects boxes from a picture. I am using a cascade classifier to do that. To improve its quality I need to provide more positive samples. I have made many photos of boxes from my webcam. I need in tool to create 'good.dat'-file. I trying to use google imageclipper, but there are no results.. Is there any programms to create file Good.dat with positive object coordinates? I found some in github, but cant run them... If yes, help please with links. Thanks. p.s. Sorry for my bad english)

Take a look at It's a tutorial which makes use of ObjectMaker.exe utility to crop positive and negative samples. Download link is inside PDF file.

would opencv's annotation tool be, what you want ? (given a folder of images, it would write a text file with image names an boxes, that can be used with the createsamples tool. you also probably already have that on your box !)

if you built the opencv libs locally, this one will have been built, too ! have another look at your opencv installation !

I cannot enable local tools, which comes with errors, just cannot run
