Hello,how much does the traincascade application scales the negative images in the grabbing process at the start of each stage?I understand it uses a sliding window sized accordingly to your model parameters (-w,-h) on the images when searching for negative samples but i am curious about the scaling parameter,is it the default value 1.1?

Forget my previous comment, which I deleted because it was plain wrong

Taking a look at the negative image grabber you can see that the scaling step of the negative samples is defined by the model dimensions and the image dimensions provided. The exact line of defining this scale step is found here.

The scaleFactor itself is hardcoded right here and is used to define the new scale for each step.
