# Example: Bardcodes

<span style="color: rgb(0, 0, 0);">Any image/photo entering the Free Form language computational container is immediately processed for:</span>

- <span style="color: rgb(0, 0, 0);">Any faces? if yes, highlight and cutout the facial regions and compute them (their properties).</span>
- <span style="color: rgb(0, 0, 0);">Any barcodes or qr-codes? if yes, highlight the barcode regions and read them.</span>
- <span style="color: rgb(0, 0, 0);">Any texts? if yes, OCR the image.</span>
- <span style="color: rgb(0, 0, 0);">Add the necessary post-processing e.g. image annotations</span>
- <span style="color: rgb(0, 0, 0);">Finally collect at the resulting metadata tags 𖤘 and contents ⚲ (to be hashed) and URL export as String</span>

**Case 1**<span style="color: rgb(0, 0, 0);">: Single image multiple barcodes only</span>
