Count shapes

POST /api/image-count

Count distinct objects (blobs) in an image. Configurable size and brightness thresholds. Useful for cell counting, particle counting, and inventory checks.

Detects and counts distinct objects (connected blobs) in an image. Configurable thresholds tune what counts as a "blob" (minimum size in pixels, brightness range, etc.). Useful for cell-culture counting, particle counts in scientific imagery, and quick inventory checks where the objects are clearly separated from the background.
