How to parse "tsv" file to use detected features?

Parse in what manner? You can read a TSV file in the same way you read a CSV, except that the delimiter will be the tab character ("\t" I believe) instead of a comma. Then the field names should be as follows: image_id, image_w, image_h, num_boxes, boxes, features.
