Analyzing image size and aspect ratio
It is very important to understand the distribution of image sizes and aspect ratios in image data models.
Aspect ratio, in the context of image dataset EDA, refers to the proportional relationship between the width and height of an image. It’s a numerical representation that helps describe the shape of an image. Aspect ratio is especially important when working with images, as it provides insights into how elongated or compressed an image appears visually. Mathematically, the aspect ratio is calculated by dividing the width of the image by its height. It’s typically expressed as a ratio or a decimal value. A square image has an aspect ratio of 1:1, while a rectangular image would have an aspect ratio different from 1:1.
Impact of aspect ratios on model performance
Let’s understand the impact of aspect ratios on the model performance using the following points:
