Dataset Card for Material Classification

Dataset Summary

The Material_classification_2U dataset consists of 150 256x256 color images, categorized into 5 classes with 30 images per class. The dataset is divided into two main subsets: 120 images for training and 30 images for testing. Each image is labeled into one of the following five categories: Brick, Metal, Paper, Plastic, and Wood.

Supported Tasks and Leaderboards

• image-classification: The goal of this task is to classify a given image into one of 5 classes.

Dataset Structure

Data Instances

A sample from the training set is provided below:

{
  'image': <PIL.PngImagePlugin.PngImageFile image mode=RGB size=256x256>,
  'label': 1
}

Data Fields

• image: A PIL.Image.Image object containing the 256x256 image. Note that when accessing the image column: dataset['train']["image"] the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time.
• label: 0-4 with the following correspondence '0': Brick '1': Metal '2': Paper '3': Plastic '4': Wood

Data Splits

The dataset is divided into two main subsets: Train and Test.

• Train Split:
  • Number of Images: 120
  • Distribution: 24 images per class
• Test Split:
  • Number of Images: 30
  • Distribution: 6 images per class

Both splits are stratified, ensuring that each class is proportionally represented in both the Train and Test subsets. This means that the percentage of images for each class remains consistent across both splits, providing a balanced and representative distribution for model training and evaluation.
