How to Use Computer Vision for Environment Monitoring

SUMMARY Satellite and drone imagery analyzed by computer vision models can measure environmental change at a scale and frequency that manual scientific monitoring cannot match, turning pixel data into quantifiable ESG metrics like built-up area, deforestation extent, water coverage, and crop health. This guide walks through building a remote

Detect and Segment Oil Spills Using Computer Vision

SUMMARY Drone footage of an oil spill carries enough information to determine spill volume, thickness, and spatial extent, but only if the imagery is analyzed with a model trained to distinguish those properties. This post walks through building an instance segmentation model that labels oil spill regions by thickness class,

Build a Chess Game Recorder with Computer Vision

SUMMARY Clio, built by the team at A1H1, is a portable chess recording device that uses computer vision instead of embedded sensors to digitize over-the-board games, bringing the cost well below the roughly $500 USD of sensor-equipped commercial sets. The system handles two distinct problems: detecting the

Prompting Google Bard with Images & How it Compares to Bing

SUMMARY Google Bard's image input capabilities, tested against counting, object detection, and classification tasks using datasets from Roboflow Universe, fall short of Bing/GPT-4 for structured computer vision work. Bard refuses images containing human faces entirely rather than blurring them, and it undercounts objects even in straightforward

Improve Accuracy: Polygon Annotations for Object Detection

SUMMARY Polygon annotations consistently outperform bounding boxes for object detection when objects have irregular shapes, because polygons eliminate background noise that bounding boxes include. An experiment comparing both annotation types, combined with augmentations (rotation, saturation, cutout, bounding box shear) and pretrained weight initialization, showed meaningful mAP gains at each step.
