Prismer is a versatile model that can handle both visual question answering and image captioning tasks. The model takes in an input image and either a question (for visual question answering) or no additional input (for image captioning). The model's output varies depending on the chosen task, but can include the generated caption, the answer to the visual question, or the expert model labels.

Inputs

  • Input Image: The input image, which can be in .png, .jpg, or .jpeg format.
  • Question (optional): The question to be answered for the visual question answering task.
  • Use Experts: A boolean flag to indicate whether the expert models should be used.
  • Output Expert Labels: A boolean flag to return the output of the individual expert models.

Outputs

  • Caption: The generated caption describing the input image (for the image captioning task).
  • Answer: The answer to the visual question (for the visual question answering task).
  • Expert Labels: The output of the individual expert models (if Output Expert Labels is set to true).

Capabilities

Prismer is a powerful model that can tackle a wide range of vision-language tasks. Its ensemble-based approach allows it to leverage the strengths of multiple specialized models, resulting in robust and versatile performance. The model can accurately caption images, answer visual questions, and provide insights into the internal decision-making process through the expert labels.

What can I use it for?

Prismer can be used in a variety of applications that require integrating vision and language understanding, such as:

  • Intelligent image search and retrieval
  • Automated image captioning for social media or e-commerce
  • Visual question answering for assistive technologies
  • Multimodal content analysis and understanding

Things to try

BLIP (Bootstrapping Language-Image Pre-training) is a vision-language model developed by Salesforce that can be used for a variety of tasks, including image captioning, visual question answering, and image-text retrieval. The model is pre-trained on a large dataset of image-text pairs and can be fine-tuned for specific tasks. Compared to similar models like blip-vqa-base, blip-image-captioning-large, and blip-image-captioning-base, BLIP is a more general-purpose model that can be used for a wider range of vision-language tasks. Model inputs and outputs BLIP takes in an image and either a caption or a question as input, and generates an output response. The model can be used for both conditional and unconditional image captioning, as well as open-ended visual question answering. Inputs Image**: An image to be processed Caption**: A caption for the image (for image-text matching tasks) Question**: A question about the image (for visual question answering tasks) Outputs Caption**: A generated caption for the input image Answer**: An answer to the input question about the image Capabilities BLIP is capable of generating high-quality captions for images and answering questions about the visual content of images. The model has been shown to achieve state-of-the-art results on a range of vision-language tasks, including image-text retrieval, image captioning, and visual question answering. What can I use it for? You can use BLIP for a variety of applications that involve processing and understanding visual and textual information, such as: Image captioning**: Generate descriptive captions for images, which can be useful for accessibility, image search, and content moderation. Visual question answering**: Answer questions about the content of images, which can be useful for building interactive interfaces and automating customer support. Image-text retrieval**: Find relevant images based on textual queries, or find relevant text based on visual input, which can be useful for building image search engines and content recommendation systems. Things to try One interesting aspect of BLIP is its ability to perform zero-shot video-text retrieval, where the model can directly transfer its understanding of vision-language relationships to the video domain without any additional training. This suggests that the model has learned rich and generalizable representations of visual and textual information that can be applied to a variety of tasks and modalities. Another interesting capability of BLIP is its use of a "bootstrap" approach to pre-training, where the model first generates synthetic captions for web-scraped image-text pairs and then filters out the noisy captions. This allows the model to effectively utilize large-scale web data, which is a common source of supervision for vision-language models, while mitigating the impact of noisy or irrelevant image-text pairs.
