实际评估segment-anything-video时，我先确认它解决的具体问题：MetaSeg：Segment Anything 存储库的打包版本。一旦进入视频制作环节，素材、节奏、编码和最终画面容易不一致会直接影响交付，这也是我最关心的风险。我的评估方法是拿一组已有素材完成一段短样片，然后检查素材路径、渲染结果、音画同步和导出格式是否与文档一致。如果团队属于有真实素材并需要稳定视频产出的创作者，它有继续测试的理由；否则先看替代方案会更省时间。

MetaSeg: Packaged version of the Segment Anything repository

此存储库是 分段任意 模型的打包版本。

安装

pip install metaseg

用途

from metaseg import SegAutoMaskPredictor, SegManualMaskPredictor

# If gpu memory is not enough, reduce the points_per_side and points_per_batch.

# For image
results = SegAutoMaskPredictor().image_predict(
    source="image.jpg",
    model_type="vit_l", # vit_l, vit_h, vit_b
    points_per_side=16,
    points_per_batch=64,
    min_area=0,
    output_path="output.jpg",
    show=True,
    save=False,
)

# For video
results = SegAutoMaskPredictor().video_predict(
    source="video.mp4",
    model_type="vit_l", # vit_l, vit_h, vit_b
    points_per_side=16,
    points_per_batch=64,
    min_area=1000,
    output_path="output.mp4",
)

# For manuel box and point selection

# For image
results = SegManualMaskPredictor().image_predict(
    source="image.jpg",
    model_type="vit_l", # vit_l, vit_h, vit_b
    input_point=[[100, 100], [200, 200]],
    input_label=[0, 1],
    input_box=[100, 100, 200, 200], # or [[100, 100, 200, 200], [100, 100, 200, 200]]
    multimask_output=False,
    random_color=False,
    show=True,
    save=False,
)

# For video

results = SegManualMaskPredictor().video_predict(
    source="video.mp4",
    model_type="vit_l", # vit_l, vit_h, vit_b
    input_point=[0, 0, 100, 100],
    input_label=[0, 1],
    input_box=None,
    multimask_output=False,
    random_color=False,
    output_path="output.mp4",
)

SAHI + 段任何内容

pip install sahi metaseg

from metaseg.sahi_predict import SahiAutoSegmentation, sahi_sliced_predict

image_path = "image.jpg"
boxes = sahi_sliced_predict(
    image_path=image_path,
    detection_model_type="yolov5",  # yolov8, detectron2, mmdetection, torchvision
    detection_model_path="yolov5l6.pt",
    conf_th=0.25,
    image_size=1280,
    slice_height=256,
    slice_width=256,
    overlap_height_ratio=0.2,
    overlap_width_ratio=0.2,
)

SahiAutoSegmentation().image_predict(
    source=image_path,
    model_type="vit_b",
    input_box=boxes,
    multimask_output=False,
    random_color=False,
    show=True,
    save=False,
)

FalAI(云 GPU) + 分段任何内容

pip install metaseg fal_serverless
fal-serverless auth login

# For Auto Mask
from metaseg import falai_automask_image

image = falai_automask_image(
    image_path="image.jpg",
    model_type="vit_b",
    points_per_side=16,
    points_per_batch=32,
    min_area=0,
)
image.show() # Show image
image.save("output.jpg") # Save image

# For Manual Mask
from metaseg import falai_manuelmask_image

image = falai_manualmask_image(
    image_path="image.jpg",
    model_type="vit_b",
    input_point=[[100, 100], [200, 200]],
    input_label=[0, 1],
    input_box=[100, 100, 200, 200], # or [[100, 100, 200, 200], [100, 100, 200, 200]],
    multimask_output=False,
    random_color=False,
)
image.show() # Show image
image.save("output.jpg") # Save image
