Labeling Experience

Cyvl

CVATImageBounding BoxPolygon

The CYVL project involved the annotation of up to 50,000 images aimed at identifying both the materials used in road construction (e.g., asphalt, concrete, gravel) and various road surface defects such as potholes, cracks, repairs, and worn-out road markings. The scope required detailed classification and segmentation to support AI models used in automated road condition assessments and maintenance planning. Accuracy and consistency were critical, as the data contributed to infrastructure monitoring systems and smart city applications.

Avid Exchange

CloudfactoryVideoData Collection

The AvidXchange project focused on extracting structured data from scanned invoices, including key fields such as "Ship To," "Bill To," Invoice Number, PO Number, Work Order, Date, Account Number, and other relevant billing details. The scope involved reviewing a high volume of diverse invoice formats and accurately capturing text using OCR and manual validation. This ensured clean, reliable data for accounts payable automation and financial processing, with a strong emphasis on data accuracy, consistency, and meeting turnaround time requirements.
