Overview

Evaluates whether a still image is sufficiently sharp.

​
Configuration

This detector does not accept configuration keys.

​
Example Configuration

{
  "detector_name": "image_sharpness",
  "config": {}
}

​
Result Schema

{
  "detector_name": "image_sharpness",
  "pass_check": true,
  "score": 0.78,
  "rationale": "Image appears sharp enough for large-format printing",
  "metrics": {
    "base_score": 31.2,
    "downscaled_score": 28.7,
    "crop_score": 27.4,

Interpreting Results

  • base_score/downscaled_score/crop_score: Core sharpness measurements used for pass/fail.
  • min_ thresholds*: The minimum scores required to pass.
  • upscaled_score: Included only when upscaling checks are enabled.
