Computer vision enables powerful video analysis capabilities. Here's how I build production CV pipelines.
Pipeline Architecture
1. Video Processing
- Frame extraction
- Preprocessing
- Batch processing
2. Object Detection
- Model selection
- Inference optimization
- Post-processing
3. Annotation
- Automated labeling
- Quality assurance
- Export formats
Performance Optimization
- GPU acceleration
- Batch processing
- Caching strategies
- Parallel processing
Example Implementation
import cv2
def process_video(video_path):
cap = cv2.VideoCapture(video_path)
while cap.isOpened():
ret, frame = cap.read()
if not ret:
break
# Process frame
results = detect_objects(frame)
annotate_frame(frame, results)
cap.release()
— end —
