Image Captioning with BLIP

author: David Wang

Description

This operator generates the caption with BLIP which describes the content of the given image. This is an adaptation from salesforce/BLIP.

Code Example

Load an image from path './animals.jpg' to generate the caption.

Write the pipeline in simplified style:

      .image_decode() \
      .image_captioning.blip(model_name='blip_base') \
      .select() \
      .show()

Write a same pipeline with explicit inputs/outputs name specifications:

import towhee

towhee.glob['path']('./animals.jpg') \
      .image_decode['path', 'img']() \
      .image_captioning.blip['img', 'text'](model_name='blip_base') \
      .select['img', 'text']() \
      .show()
