I have extracted features for the feature points in the entire frame. How to select the features in ROI using annotations? (Annotations of ROI are available in the dataset.)

ReDID dataset .. Ya Since i need to use only the decriptors inside ROI for the next step.. I need to select those inside the envelope defined in annotation.

This cannot be that difficult right? Each keypoint will have a seed point from the keypoint detector and a range in which the descriptor is calculated. Use that info to make sure you are still inside the window of the ROI, which is the annotation in this case. It is simply comparing x and y coordinates...
