What is a .vec file?
I'm just yesterday start using OpenCV to train Cascade Classifier. I use createsamples, and it gave me .vec file. What is that this file? I cant find any explanation about this file. How load it into program(VS10), how to display the data in it, etc...
You should read into the documents, which explains that the vec file contains actually the model training data formatted correctly for efficient training. Look here and here.
