What is a good project combining computer vision and NLP?
There are several projects which involve integrating computer vision and NLP, but some are determined as efficient. We offer an extensive plan for a project that combines both of these domains:
Project: Visual Storytelling from Image Sequences
Goal: By employing the advantages of computer vision as well as natural language processing, construct a model that produces consistent narratives or stories from a series of images.
Application Areas:
- For event photography, used in constructing automated lectures or storytelling.
- It is utilized in developing story narratives from photo albums.
- In generating stories and captions for academic materials.
Major Components and Methodology:
- Dataset Preparation
- Dataset Instances:
- VIST (Visual Storytelling Dataset): This dataset involves image series along with ground-truth stories.
- MS COCO Captions Dataset: It offers captions for individual images.
- Flickr8k/Flickr30k: This dataset encompasses the image-caption pairs.
- Preprocessing Steps:
- By utilizing OpenCV, assure coherent image sizes.
- Aim to tokenize and cleanse text stories through employing NLP preprocessing tools.
- Image Feature Extraction
- By means of employing a pre-trained convolutional neural network (CNN), focus on obtaining visual characteristics from every image in the series.
Instance Code (Image Feature Extraction using ResNet):
import torch
import torchvision.models as models
import torchvision.transforms as transforms
from PIL import Image
# Load pre-trained ResNet model
resnet = models.resnet50(pretrained=True)
resnet.eval()
modules = list(resnet.children())[:-1]
resnet = torch.nn.Sequential(*modules)
# Image preprocessing
transform = transforms.Compose([
transforms.Resize((224, 224)),
transforms.ToTensor(), transforms.Normalize(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225])
])
