Vision Systems That Catch Defects Before Customers Do

We build computer vision models that detect objects, read documents, inspect parts and watch video streams, tuned on your own images and edge cases. They run on cameras at the line, on Jetson devices or in your cloud.

What Cameras Can Do for Your Operations

Vision pays off where people spend hours looking at things: parts, papers, shelves, screens or sites.

  • Operator running machinery on a production line

    Visual inspection and defect detection

    Models that find scratches, dents, missing components, misprints and weld flaws on the production line, trained on your good and bad samples.

    Consistent inspection on every part, every shift

  • Two colleagues checking extracted document fields at a desk

    OCR and document AI

    Extraction from invoices, IDs, bills of lading, forms and handwritten notes, with layout understanding and field-level confidence for review.

    Data entry replaced by checking flagged fields

  • Two CCTV cameras mounted on a wall

    Video analytics

    Counting, tracking and zone rules on CCTV and IP camera feeds for footfall, queue length, dwell time and safety gear compliance.

    Live operational data from cameras you already own

  • Warehouse shelving filled with boxed inventory

    Logistics and inventory

    Package dimensioning, label and barcode reading, pallet counting and damage detection at docks and in warehouses.

    Fewer mis-shipments and faster receiving

  • Construction workers in hard hats and high-visibility vests

    Workplace safety

    Detection of missing helmets or vests, people in restricted zones and unsafe forklift proximity, with alerts sent to supervisors.

    Incidents spotted while they can still be prevented

  • Grocery store aisle stocked with products

    Retail shelf and product recognition

    Planogram compliance, out-of-stock detection and product recognition from shelf photos taken by staff or fixed cameras.

    Shelf gaps found in minutes, not on the next audit

Vision Capabilities We Build and Tune

Accuracy in a demo is easy. Accuracy under your lighting, angles and part variations is the actual work.

  • Inspector measuring a machined part with calipers
  • Object detection and tracking

    YOLO and DETR family detectors with multi-object tracking, measured in mAP and tuned for your object sizes and frame rates.

  • Segmentation

    Pixel-level masks with SAM and custom segmentation models for measuring defect area, sizing items or isolating regions.

  • OCR and layout parsing

    Text, tables and key-value extraction from scans and photos, combining OCR engines with layout models for structured output.

  • Anomaly detection

    Models trained mostly on good parts that flag anything unusual, useful when defect samples are rare.

  • Data labeling and curation

    Labeling guidelines, active learning to pick the most useful images, and synthetic data to cover rare defects.

  • Edge deployment

    Models quantized and compiled with TensorRT for NVIDIA Jetson and other edge hardware, so inference runs next to the camera.

  • Technician testing an electronic circuit at her bench
  • Camera and stream integration

    RTSP and GigE camera ingestion, PLC triggers and reject signals, so the model fits into the line instead of beside it.

  • Review and feedback loop

    Low-confidence results go to a reviewer, and their corrections flow back into the next training round.

Vision AI With Clear Limits

Cameras capture people, documents and sensitive sites, so privacy and error handling are designed in from day one.

Faces and plates blurred on the device, before any frame is stored.

  • Measured error trade-offs

    We tune thresholds with you on false reject rate and miss rate per defect type, so the balance between scrap cost and escapes is your decision.

  • Privacy by design

    Face and license plate blurring, on-device processing and short retention windows keep personal data out of storage where it is not needed.

  • Held-out test sets

    A frozen image set covering lighting changes, new part batches and rare defects scores every model before it reaches the line.

  • Human review on doubt

    Low-confidence predictions are never auto-actioned. They go to a reviewer with the image, the mask and the model's reasoning.

[ FAQ ]

Computer Vision Questions

Still deciding? A 30-minute call usually answers the rest.

Ask Us Directly
  • For a focused detection task, a few hundred well-labeled images per class is often enough to start, because we fine-tune pretrained models. Rare defects can be covered with anomaly detection or synthetic images. The feasibility study tells you what your data supports.

  • A prototype on your sample images starts from $2,500, a production system at one site from about $15,000, and multi-site platforms from $40,000. Cameras, lighting and edge devices are extra and depend on line speed and resolution.

  • We cannot promise a number before seeing your images, but we measure it early. The feasibility study gives an estimate, and every model is scored on held-out images using mAP, recall and false reject rate before it goes live.

  • Edge devices such as NVIDIA Jetson suit production lines that need decisions in tens of milliseconds or have limited bandwidth. Cloud inference suits document processing and batch video analysis. Many setups use both, with the edge doing detection and the cloud doing retraining.

  • Usually yes. We connect to RTSP, ONVIF and GigE Vision cameras. If image quality is the limiting factor, we recommend specific lighting or lens changes, which often matter more than the model.

  • Vision-language models like GPT and Gemini are useful for open-ended questions about images and for low-volume tasks. For high-volume inspection with strict latency and cost limits, a fine-tuned detector is faster, cheaper per image and more consistent.

  • We blur faces and plates on device, avoid storing raw video where it is not needed and set short retention periods. Processing can stay fully on premises if your policies require it.

  • Monitoring tracks confidence and reject rates per station. When they shift, reviewer-corrected images feed a retraining round, and the new model is tested on the frozen test set before it is rolled out.

  • You do. Labeled images, trained weights, deployment code and documentation all belong to you, with the source code and IP fully transferred.
