使用YOLOv8预测模型可以在新的图像或视频上进行物体检测和分类。在Python中,可以使用ultralytics库中的YOLO类来加载和使用YOLOv8模型。可以通过以下步骤进行预测:
1. 导入所需的库:
```
from ultralytics import YOLO
from PIL import Image
import cv2
```
2. 加载YOLOv8模型:
```
model = YOLO("model.pt")
```
3. 使用预训练模型进行预测:
```
# 预测单个图像或视频帧
results = model.predict(source="image.jpg")
# 预测包含多个图像或视频帧的文件夹
results = model.predict(source="folder", show=True)
# 预测并保存绘制的图像
im1 = Image.open("image.jpg")
results = model.predict(source=im1, save=True)
# 预测并保存绘制的图像和标签
im2 = cv2.imread("image.jpg")
results = model.predict(source=im2, save=True, save_txt=True)
# 预测多个图像或视频帧
results = model.predict(source=[im1, im2])
```
通过这些步骤,您可以使用YOLOv8预测模型对图像或视频进行物体检测和分类。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
