When image values are only slightly different, floating-point errors can cause a subtraction inside of a square root to go negative (without an explicit check that was added to `match_template`). rrg& .>)r6r6r)rOrNr7)rrrnormalonesranyisnanr&rGr+s r2 test_no_nansrUNsINN1 $))x)888 8EwvHHRaRUO E8 , ,Fvbhv&&'''''''r4ctjd}tjd}tjt5t ||ddddS#1swxYwYdS)Nrrr7r7rrQr raises ValueErrorrr&rGs r2test_switched_argumentsr]]s GFOOEwvH  # #((x'''((((((((((((((((((sA  A$'A$cdtdz}dtjdz}tdd}||ddfxx|ddddfzcc<||dd fxx|z cc<||d d fxx|zcc<||ddfxx|ddddfz cc<t ||d | }tj|j}tj|dd|j \}}t|dtj|dd|j \}}t|ddS)aeTest `match_template` when `pad_input=True`. This test places two full templates (one with values lower than the image mean, the other higher) and two half templates, which are on the edges of the image. The two full templates should score the top (positive and negative) matches and the centers of the half templates should score 2nd. rr) Nr7r_iT) pad_inputconstant_values)r8r)rO) rrrQslicermeanr$r;r<r=r)rGr&midr+rHijs r2test_pad_inputrndstWQZZH "''"" "E 1++C #rr'NNNhqqq"##v&&NNN #qs(OOOxOOO #r"u*! #rss(OOOx2A2&OOO  x4F Jv{++M M"1"-v| < rsLEEEEEEEE&&&&&&&&&&&&&&::::::::######Wrz2:677++87+>!2!2!2H ( ( ((((: M M M M M MJJJ((("$$$$$r4
