matlab - How to plot miss rate vs false positive rate? -

i have problem plot curve miss rate vs false positive rate analyze performance of proposed system (as sampled on picture below). have 2 samples dataset positive , negative sample. want plot performance of system whether can classify people or non people curve.

as far know, need true positive , false positive values after classification, not sure yet how plot curve. 1 can please??

there 2 type of bounding boxes in object detection, boxes data-set labeled theme object , second boxes algorithm detects.

if bbox have huge intersection data-set bbox, okey.

if bbox have not intersection data-set bbox false posative.

and call data-set bbox without intersection bbox in image miss rate. , after calculating these numbers, plotting these values straight forward.
