Computer vision has stopped being a laboratory technology. Today, any web application can integrate visual recognition capabilities using APIs and models that run in the browser.
Available technologies
Cloud APIs: Google Cloud Vision, AWS Rekognition, and Azure Computer Vision offer complete APIs for image analysis. They detect objects, faces, text, emotions, and inappropriate content.
Browser models: TensorFlow.js and ONNX Runtime allow running vision models directly in the browser, without sending images to external servers.
Multimodal model APIs: GPT-5, Claude 4, and Gemini 3 can analyze images as part of their input, enabling descriptions, questions, and visual reasoning.
Practical use cases
Visual search: Allow users to search products by uploading a photo instead of typing text. Ideal for ecommerce and catalogs.
Content moderation: Automatically detect inappropriate images on user-generated content platforms.
Text extraction (OCR): Extract text from images, invoices, IDs, or license plates to automate processes.
Web augmented reality: Use the device camera to overlay digital information on the real world, without native apps.
Quality control: Analyze product images in real-time to detect defects on production lines.
Implementation with multimodal APIs
Multimodal APIs dramatically simplify implementation. A single call to GPT-5 or Gemini 3 can describe an image, answer questions about it, and extract text, all in one step.
response = client.chat.completions.create(
model="gpt-5",
messages=[{"role": "user", "content": [
{"type": "text", "text": "Describe this image"},
{"type": "image_url", "image_url": {"url": url}}
]}]
)
Performance considerations
Cloud APIs offer the best accuracy but add network latency. Browser models are faster but less accurate. The choice depends on your use case.
