About Mahjong_detect Dataset

This dataset contains image cloned from ICanReadMahjong and Mahjong Tiles, in which the missing annotations in the original Mahjong Tiles are added.

Use Free F1, F2 and F3 Detection API

Powered by general detection model

Code
pip install inference-sdk
# 1. Import the library
from inference_sdk import InferenceHTTPClient

# 2. Connect to your workspace
client = InferenceHTTPClient(
  api_url="https://serverless.roboflow.com",
  api_key="API_KEY"
)

# 3. Run your workflow on an image
result = client.run_workflow(
  workspace_name="<YOUR_WORKSPACE>",
  workflow_id="<YOUR_WORKFLOW_ID>",
  images={
    "image": "YOUR_IMAGE.jpg"  # Path to your image file
  },
  parameters={
    "classes": "f1, f2, f3, f4, f5"
  },
  use_cache=True  # cache workflow definition for 15 minutes
)

# 4. Get your results
print(result)
