Recognition API

CoolR's computer vision API performs various steps:

1. Stitch: CoolR's WiFi Vista uses 2 cameras to capture more area. These images are stitched together to create a single image.
2. Obfuscate human body parts
3. Identify area of interest: Any area outside the area of interest (asset) is discarded
4. Segment the view into shelves/ baskets
5. Identify products and empty spaces
6. Identify stacking
7. Identify any labels
8. Identify SKUs for products

The API returns the results in JSON format:

Note: For brevity, data is truncated.

The response contains an array of shelves, each containing an array of products. Each product includes:

1. product
2. sku array (if multiple products/ stacked)
3. confidence level (%)
4. data - product coordinates
5. position - guessed position on the shelf (left to right)
6. capacity - if there is any open capacity at this position
7. stacked - an array of additional stacked products
