I getting problem in understanding the sentence
Alpha indicates the IoU (Intersection over Union) for neighbouring candidate boxes; step sizes of the sliding windows are determined such that one step results in an IoU of Alpha.
What I understand is: The value of Alpha (which is step size) is actually the IoU (Intersection over Union) for neighbouring candidate boxes ;(further explanation of this previous sentence.) step sizes of the sliding windows can be calculated as one step produce in an IoU of Alpha.
I couldn't understand the meaning of "in an IoU of Alpha." Anyone please help me to explain this in simple words or with example
