CNN-MNN Model for Image Captioning This repository contains the CNN-MNN model for generating image captions. This model leverages a Convolutional Neural Network (CNN) for image encoding and a Multi-Head Attention Network (MNN) for decoding to produce descriptive captions.

Model Description The CNN-MNN model is designed to generate captions for images by encoding visual information and decoding it into coherent text descriptions.

Model Card Model Type: CNN-MNN for Image Captioning Pretrained Weights: Available on Hugging Face Model Hub (update with actual path if applicable) Licenses: Apache License 2.0 Installation You can install the required libraries using pip:

bash Copy code pip install transformers torch torchvision pillow Usage Here’s a simple example of how to use the model for image captioning:

python Copy code from transformers import VisionEncoderDecoderModel, ViTImageProcessor, AutoTokenizer import torch from PIL import Image

Load the model and processors

model = VisionEncoderDecoderModel.from_pretrained('your_username/cnn-mnn-model') # Update with your model path feature_extractor = ViTImageProcessor.from_pretrained('your_username/cnn-mnn-model') tokenizer = AutoTokenizer.from_pretrained('your_username/cnn-mnn-model')

Set device

device = torch.device('cuda' if torch.cuda.is_available() else 'cpu') model.to(device)

Generation parameters

max_length = 16 num_beams = 4 gen_kwargs = {'max_length': max_length, 'num_beams': num_beams}

def predict_step(image_paths): images = [] for image_path in image_paths: i_image = Image.open(image_path) if i_image.mode != 'RGB': i_image = i_image.convert(mode='RGB') images.append(i_image)

pixel_values = feature_extractor(images=images, return_tensors='pt').pixel_values
pixel_values = pixel_values.to(device)

output_ids = model.generate(pixel_values, **gen_kwargs)

preds = tokenizer.batch_decode(output_ids, skip_special_tokens=True)
preds = [pred.strip() for pred in preds]
return preds

Example usage

captions = predict_step(['your_image_path.jpg']) # Update with your image path print(captions) Sample Running Code Using Transformers Pipeline You can also use the Transformers pipeline for a simpler interface:

python Copy code from transformers import pipeline

Create the image-to-text pipeline

image_to_text = pipeline('image-to-text', model='your_username/cnn-mnn-model') # Update with your model path

Generate caption for an image from a URL

caption = image_to_text('https://example.com/path/to/your/image.jpg') # Update with an actual image URL print(caption) Model Performance The model has been evaluated on standard image captioning benchmarks. Refer to the associated documentation for details on performance metrics and datasets.
