Street Squatting Detection

Street Squatting Detection

Algorithm Introduction
Algorithm Introduction
Leveraging AI vision algorithms, this solution focuses on nighttime road and curb scenarios, accurately identifying squatting pedestrians (particularly intoxicated individuals). It outputs bounding boxes and counts of squatting individuals, helping to control the volume of police incidents and reduce personal and property losses for citizens.
  • ● Brightness Requirements: The overall brightness ratio of the image (proportion of bright pixels/regions to total pixels) must not be lower than 50%. Bright pixels are defined as having a grayscale value greater than 40.
  • ● Image Requirements: Optimal detection performance is achieved at a resolution of 1344×768.
  • ● Target Size: For standard 1080p (1920×1080) video streams, the minimum detectable target size is 60×120 pixels, and the maximum detectable target size is 512×512 pixels.

FAQ

  • Algorithm Accuracy
    All 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.
  • Deployment & Inference
    We offer multiple deployment formats—Models, Applets and SDKs.
    Compatibility has been verified with more than ten domestic chip vendors, including Huawei Ascend, Iluvatar, and Denglin, ensuring full support for China-made CPUs, GPUs, and NPUs to meet high-grade IT innovation requirements.
    For each hardware configuration, we select and deploy a high-accuracy model whose parameter count is optimally matched to the available compute power.
  • How to Customize an Algorithm
    All 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.
