from ultralytics import YOLO
# Load a model

# Run batched inference on a list of images
results = model(['im1.jpg', 'im2.jpg']) # return a list of Results objects
# Process results list
for result in results:

masks = result.masks # Masks object for segmentation masks outputs
keypoints = result.keypoints # Keypoints object for pose outputs
probs = result.probs # Probs object for classification outputs
print(masks )
從API我們可以得知，若我們使用的是yolo-seg，則吐回的座標資訊可參考這個返回值

設定folder_path到images的資料夾，label會放到相對應的labels資料夾下
from ultralytics import YOLO
from PIL import Image
import cv2
import os
# 資料夾路徑
folder_path = './datasets/coco8-seg/images/train'
images = []
# 確保資料夾存在
if not os.path.exists(folder_path):
print("資料夾不存在")
else:
# 取得資料夾內所有檔案
file_list = os.listdir(folder_path)
# 遍歷每個檔案
for filename in file_list:
# 確保檔案是圖片檔案（可根據您的需求調整）
if filename.lower().endswith(('.png', '.jpg', '.jpeg')):
# 構建完整的檔案路徑
file_path = os.path.join(folder_path, filename)
images.append(file_path)
# Load a model
model = YOLO('yolov8n-seg.pt') # pretrained YOLOv8n model
# Run batched inference on a list of images
results = model(images) # return a list of Results objects
# Show the results
