Computer Vision Pipeline: Object Detection, Classification, and Search

Build optimized computer vision workflows with Pixeltable. Run YOLOX, CLIP, and custom models as computed columns with automatic batching, caching, and incremental processing.

The Challenge

Computer vision pipelines require managing image preprocessing, running multiple models (detection, classification, embedding), storing results, and keeping everything in sync. Adding a new model or changing thresholds means reprocessing millions of images manually.

The Solution

Pixeltable makes CV pipelines declarative. Define models as computed columns, and Pixeltable handles execution, batching, caching, and incremental updates. Change a threshold and only affected results are recomputed.

Implementation Guide

Step-by-step walkthrough with code examples

Step 1 of 4

Image Table

Create a table for images with metadata tracking.

python

1import pixeltable as pxt
2
3# Create image processing pipeline
4images = pxt.create_table('app.images', {
5    'image': pxt.Image,
6    'source': pxt.String,
7    'timestamp': pxt.Timestamp,
8    'camera_id': pxt.String,
9})
10
11# Insert images — local, S3, or URL
12images.insert([
13    {'image': 's3://bucket/cam01/frame_001.jpg',
14     'source': 'warehouse', 'camera_id': 'cam-01'},
15    {'image': '/data/inspection/part_42.png',
16     'source': 'qc-station', 'camera_id': 'cam-02'},
17])

Images are stored as native types with full metadata. No separate image registry or file management.
