Sam2.1 Hiera Large

許可協議：apache-2.0
任務類型：掩碼生成
庫名稱：sam2

SAM 2（Segment Anything in Images and Videos）項目庫，這是FAIR研發的面向圖像與視頻可提示視覺分割的基礎模型。更多信息請參閱SAM 2論文。

官方代碼已在此代碼庫公開。

使用說明

圖像預測示例：

import torch
from sam2.sam2_image_predictor import SAM2ImagePredictor

predictor = SAM2ImagePredictor.from_pretrained("facebook/sam2-hiera-large")

with torch.inference_mode(), torch.autocast("cuda", dtype=torch.bfloat16):
    predictor.set_image(<你的圖像>)
    masks, _, _ = predictor.predict(<輸入提示>)

視頻預測示例：

import torch
from sam2.sam2_video_predictor import SAM2VideoPredictor

predictor = SAM2VideoPredictor.from_pretrained("facebook/sam2-hiera-large")

with torch.inference_mode(), torch.autocast("cuda", dtype=torch.bfloat16):
    state = predictor.init_state(<你的視頻>)

    # 添加新提示並立即獲取當前幀輸出
    frame_idx, object_ids, masks = predictor.add_new_points_or_box(state, <你的提示>):

    # 傳播提示以獲取全視頻掩碼片段
    for frame_idx, object_ids, masks in predictor.propagate_in_video(state):
        ...
