Args: masks (`tf.Tensor`): Input masks. iou_scores (`tf.Tensor`): List of IoU scores. original_size (`Tuple[int,int]`): Size of the orginal image. cropped_box_image (`np.array`): The cropped image. pred_iou_thresh (`float`, *optional*, defaults to 0.88): The threshold for the iou scores. stability_score_thresh (`float`, *optional*, defaults to 0.95): The threshold for the stability score. mask_threshold (`float`, *optional*, defaults to 0): The threshold for the predicted masks. stability_score_offset (`float`, *optional*, defaults to 1): The offset for the stability score used in the `_compute_stability_score` method. rrr|r{Nrrr) r%rreshaperrirr_compute_stability_score_tf_batched_mask_to_box_tf_is_box_near_crop_edge_tf _pad_masks_tf_mask_to_rle_tfrs rLrz"SamImageProcessor._filter_masks_tfsH $'*7'ZZ Z-=-=a-@:CSCSTUCV-VXbXhXhijikXl,mn  55;;q>EKKN#BEKKPQPRO"TU ;;q>Z--a0 0RS S[[^ GGJbgg6 S !Z/%ABI "C ':5.Rhi !%58N%NOII&i &1%8. .A~0W   "i ))4e%6X&fo--rM)NN)NNNNNNNN) NNNNNNNNNNNNN)NNNNN)rTNr)rTN)r)rg? r|NNr))\(?ffffff?rr|r)rrrr|))__name__ __module__ __qualname____doc__model_input_namesrBILINEARrrstrrar floatrrrFrrrr[r rgBICUBICrrrrrxrr rrrrrrrrrrr __classcell__)rKs@rLr+r+Cs.`((#$('9'B'B,3!:>9=!#.-.-38n.-S> .- % .-  .-c5j).-.-U5$u+#567.-E%e"456.-.-.-.-.- !.-h?CDH #zz#sCx.#eC)9$9:; # $E#/?*?$@A # #J uS#X c (:'A'A>BDH / zz/ 38n/ % / eC)9$9:; / $E#/?*?$@A /  / n*.'+*.:>9=!%-1DH*** *  * tCH~& *%*!*U5$u+#567*E%e"456**4S>**$E#/?*?$@A*B%)#'+*.'+:>9=!%-1)->BDH7979D>7938n 79 % 79  79!79tn79U5$u+#56779E%e"45679794S>*79!79eC)9$9:;79$E#/?*?$@A79 rzz5c?E#s(O; (/S> (/  (/  S#X/ (/$E#/?*?$@A(/ (/T%&37$()-.237%)6:'+:>9=!%-126)-;?(8(>(>DH'uCuC$J/uCD> uC tCH~& uC DcN+ uC/0uCTNuC!sEz!23uCtnuCU5$u+#567uCE%e"456uCuC4S>*uC S#X/uC !!uC"!sJ!78#uC$&%uC&$E#/?*?$@A'uC'uCx5Kphl-`hl(VRV^6))+>?+/DH"?I ?I  ?I "# ?I)1c(;?I(?I$E#/?*?$@A?I?IN# ;F# N.l# K.rMr+r torch.Tensorrrc(|||zkDjdtjjdtj}|||z kDjdtjjdtj}||z }|S)Nr)sumrint16int32rrr intersectionsunionsrs rLrrs .#99 :??%++?VZZ[]ejepepZq~(>>?
