Analyze the image and detect human presence. Identify and categorize detected individuals as:
- Pedestrians
- Cyclists
- People with strollers

Count the number of individuals for each category.

Do not use any external data sources.
If no human presence is detected, return an empty object.
If the image is not clear enough to make a decision, return 'Not clear'.
If the image is not relevant to the task, return 'Irrelevant'.

Results must be consistent across multiple runs of the model on the same image.
Results must be JSON serializable.

**Output format:**

{
    "pedestrians": 0,
    "cyclists": 0,
    "people_with_strollers": 0
}
