cvtools.evaluation.recall module

cvtools.evaluation.recall.eval_recalls(gts, proposals, proposal_nums=None, iou_thrs=None, print_summary=True)

Calculate recalls.

参数:

• gts (list or ndarray) -- a list of arrays of shape (n, 4)
• proposals (list or ndarray) -- a list of arrays of shape (k, 4) or (k, 5)
• proposal_nums (int or list of int or ndarray) -- top N proposals
• thrs (float or list or ndarray) -- iou thresholds

返回:

recalls of different ious and proposal nums

返回类型:

ndarray

cvtools.evaluation.recall.plot_iou_recall(recalls, iou_thrs)

Plot IoU-Recalls curve.

参数:

• recalls (ndarray or list) -- shape (k,)
• iou_thrs (ndarray or list) -- same shape as recalls

cvtools.evaluation.recall.plot_num_recall(recalls, proposal_nums)

Plot Proposal_num-Recalls curve.

参数:

• recalls (ndarray or list) -- shape (k,)
• proposal_nums (ndarray or list) -- same shape as recalls

cvtools.evaluation.recall.print_recall_summary(recalls, proposal_nums, iou_thrs, row_idxs=None, col_idxs=None)

Print recalls in a table.

参数:

• recalls (ndarray) -- calculated from bbox_recalls
• proposal_nums (ndarray or list) -- top N proposals
• iou_thrs (ndarray or list) -- iou thresholds
• row_idxs (ndarray) -- which rows(proposal nums) to print
• col_idxs (ndarray) -- which cols(iou thresholds) to print

cvtools.evaluation.recall.set_recall_param(proposal_nums, iou_thrs)

Check proposal_nums and iou_thrs and set correct format.
