Integrasi dengan Clarifai API
Untuk menggunakan Clarifai API, Anda harus menginstal paket clarifai terlebih dahulu dan menginisialisasi client-nya.

bash
Copy code
pip install clarifai
python
Copy code
from clarifai.rest import ClarifaiApp
import cv2
import base64

# Menginisialisasi Clarifai API
app = ClarifaiApp(api_key='YOUR_CLARIFAI_API_KEY')
model = app.public_models.general_model

# Fungsi untuk mengirim gambar ke Clarifai API dan mendapatkan hasil analisis
def analyze_frame(image):
    _, img_encoded = cv2.imencode('.jpg', image)
    img_base64 = base64.b64encode(img_encoded).decode('utf-8')
    response = model.predict_by_base64(img_base64)
    return response
