cleanvision 0.1.1

Find issues in image datasets

CleanVision automatically detects potential issues in image datasets like images that are: blurry, under/over-exposed, (near) duplicates, etc. This data-centric AI package is a quick first step for any computer vision project to find problems in the dataset, which you want to address before applying machine learning. CleanVision is super simple -- run the same couple lines of Python code to audit any image dataset!

Installation

pip install cleanvision

Quickstart

Download an example dataset (optional). Or just use any collection of image files you have.

wget -nc 'https://cleanlab-public.s3.amazonaws.com/CleanVision/image_files.zip'

Run CleanVision to audit the images.

from cleanvision.imagelab import Imagelab

# Specify path to folder containing the image files in your dataset
imagelab = Imagelab(data_path="FOLDER_WITH_IMAGES/")

# Automatically check for a predefined list of issues within your dataset
imagelab.find_issues()

# Produce a neat report of the issues found in your dataset
imagelab.report()

CleanVision diagnoses many types of issues, but you can also check for only specific issues.

issue_types = {"dark": {}, "blurry": {}}

imagelab.find_issues(issue_types=issue_types)

# Produce a report with only the specified issue_types
imagelab.report(issue_types=issue_types)

Clean your data for better Computer Vision

The quality of machine learning models hinges on the quality of the data used to train them, but it is hard to manually identify all of the low-quality data in a big dataset. CleanVision helps you automatically identify common types of data issues lurking in image datasets.

This package currently detects issues in the raw images themselves, making it a useful tool for any computer vision task such as: classification, segmentation, object detection, pose estimation, keypoint detection, generative modeling, etc. To detect issues in the labels of your image data, you can instead use the cleanlab package.

In any collection of image files (most formats supported), CleanVision can detect the following types of issues:

	Issue Type	Description	Issue Key	Example
1	Exact Duplicates	Images that are identical to each other	exact_duplicates
2	Near Duplicates	Images that are visually almost identical	near_duplicates
3	Blurry	Images where details are fuzzy (out of focus)	blurry
4	Low Information	Images lacking content (little entropy in pixel values)	low_information
5	Dark	Irregularly dark images (underexposed)	dark
6	Light	Irregularly bright images (overexposed)	light
7	Grayscale	Images lacking color	grayscale
8	Odd Aspect Ratio	Images with an unusual aspect ratio (overly skinny/wide)	odd_aspect_ratio

This package is still a work in progress, so expect sharp edges. Feel free to submit any found bugs or desired functionality as an issue!

CleanVision supports Linux, macOS, and Windows and runs on Python 3.7+.
