Image Quality Assessment (IQA)
IQA helps you analyze and clean up images for better quality and performance.
The IQA tool helps you analyze and clean up images. When selecting "IQA Generation" during Data Import, the system generates data for each image, including brightness, contrast, and more.
Hint
You can choose whether to perform IQA when importing a dataset.
Quick Start
Import data with IQA (image quality assessment). Click on the video below for a quick overview:
IQA Items：
Lightness： Overall lightness of an image
Contrast： Overall contrast of an image
Colorfulness： The perceived vividness of colors of an image
Max Color Kurtosis： The fourth color moment
BRISQUE： Blind/Referenceless Image Spatial Quality Evaluator
Laplacian-Blur： Applying Laplacian operator and taking maximum over the filtered pixel values
FFT-Blur： Use Fast Fourier Transform (FFT) to covert an image to the frequency domain
Use Data Visualization to filter data and apply default image parameters to remove problematic images.
Clicking on Metrics allows you to check the distribution of various image parameters, helping you quickly filter out problem images and understand the distribution of color, contrast and blurriness in the batch of images.
Use Cases
Use IQA to exclude overexposure/underexposure images
Use IQA to exclude blur images
