Angler Detection

Algorithm Introduction
Generating alerts for suspected fishing activities within designated zones, outputting alert notifications from the initial detection to the cessation of suspected fishing behavior, along with bounding boxes marking the detected areas.
- ● Brightness requirements: Minimum bright pixel ratio (grayscale value >40) of 50% in the target area
- ● Image requirements: Optimal detection performance at 1344×768 resolution
Application Value
-
Urban Lakes
The algorithm conducts real-time monitoring of designated areas such as lakeside trails and waterfront zones. Upon detecting suspected fishing activity, it immediately generates detection boxes and continuous alerts. This prevent fishing from polluting water quality and damaging ecosystems. -
Coastal Zones
The algorithm scans designated areas such as beaches and reefs for suspected anglers and outputs alerts and location data. This assists coastal management authorities in safeguarding marine ecological security and maintaining public order in coastal zones.

Algorithm AccuracyAll algorithms published on the website claim accuracies above 90 %. However, real-world performance drops can occur for the following reasons:
(1) Poor imaging quality, such as
• Strong light, backlight, nighttime, rain, snow, or fog degrading image quality
• Low resolution, motion blur, lens contamination, compression artifacts, or sensor noise
• Targets being partially or fully occluded (common in object detection, tracking, and pose estimation)
(2) The website provides two broad classes of algorithms: general-purpose and long-tail (rare scenes, uncommon object categories, or insufficient training data). Long-tail algorithms typically exhibit weaker generalization.
(3) Accuracy is not guaranteed in boundary or extreme scenarios.

How to Customize an AlgorithmAll algorithms showcased on the website come with ready-to-use models and corresponding application examples. If you need further optimization or customization, choose one of the following paths:
(1) Standard Customization (highest accuracy, longer lead time)
Requirements discussion → collect valid data (≥1 000 images or ≥100 video clips from your scenario) → custom algorithm development & deployment → acceptance testing
(2) Rapid Implementation (Monolith:https://monolith.sensefoundry.cn/)
Monolith provides an intuitive, web-based interface that requires no deep AI expertise. In as little as 30 minutes you can upload data, leverage smart annotation, train, and deploy a high-performance vision model end-to-end—dramatically shortening the algorithm production cycle.
