For To ensure the correct operation of neurocounter Neurocounter, the following object image requirements should must be met:
...
...
- clearly distinguishable by the human eye
|
...
...
- Width and height of objects in the
|
...
- image must not exceed 75% of the frame size
|
...
...
- isn't noisy and not distorted by the artifacts of compression algorithm
|
...
- The duration of the object
|
...
...
...
- Between two frames, an object must move in the
|
...
...
...
- not exceeding its size. This condition is necessary for the correct calculation of
|
...
...
...
- The minimum value of pixel density per meter is observed:
| Image resolution | Object type | Minimum pixel density per meter (ratio of the object width in pixels to the object width in meters) | Minimum object size in pixels, width x height | Ratio of the object width to the frame width as a percentage |
|---|
| 1920x1080 | Human | 55 | ~25x105 | ~3% | | 1280x720 | Human | 35 | ~17x70 | ~3% | | 640x360 | Human | 17 | ~10x42 | ~3% | | 1920x1080 | Light vehicle (2 axles) | 55 | ~354x300 | ~20% | | 1280x720 | Light vehicle (2 axles) | 35 | ~240x205 | ~20% | | 640x360 | Light vehicle (2 axles) | 17 | ~132x112 | ~20% |
