I would also be interested in this... Currently I'm using an awful hack where I write images (received as bas64) to disk and then read them using ObjectDetectionData.from_files https://github.com/Greenroom-Robotics/nuclio_lighting_flash/blob/main/nuclio_lighting_flash/flash_model_handler.py#L27

In addition to the model.serve it would be nice to have something like ObjectDetectionData.from_image which accepted pil images.
