PACS is an image dataset for domain generalization. It consists of four domains, namely Photo (1,670 images), Art Painting (2,048 images), Cartoon (2,344 images) and Sketch (3,929 images). Each domain contains seven categories.

Diabetic retinopathy is the leading cause of blindness in the working-age population of the developed world. It is estimated to affect over 93 million people. retina The US Center for Disease Control and Prevention estimates that 29.1 million people in the US have diabetes and the World Health Organization estimates that 347 million people have the disease worldwide. Diabetic Retinopathy (DR) is an eye disease associated with long-standing diabetes. Around 40% to 45% of Americans with diabetes have some stage of the disease. Progression to vision impairment can be slowed or averted if DR is detected in time, however this can be difficult as the disease often shows few symptoms until it is too late to provide effective treatment. Currently, detecting DR is a time-consuming and manual process that requires a trained clinician to examine and evaluate digital color fundus photographs of the retina. By the time human readers submit their reviews, often a day or two later, the delayed results lead to lost follow up, miscommunication, and delayed treatment. Clinicians can identify DR by the presence of lesions associated with the vascular abnormalities caused by the disease. While this approach is effective, its resource demands are high. The expertise and equipment required are often lacking in areas where the rate of diabetes in local populations is high and DR detection is most needed. As the number of individuals with diabetes continues to grow, the infrastructure needed to prevent blindness due to DR will become even more insufficient. The need for a comprehensive and automated method of DR screening has long been recognized, and previous efforts have made good progress using image classification, pattern recognition, and machine learning. With color fundus photography as input, the goal of this competition is to push an automated detection system to the limit of what is possible – ideally resulting in models with realistic clinical potential. The winning models will be open sourced to maximize the impact such a model can have on improving DR detection.

The Rotterdam EyePACS AIROGS dataset (in full, so including train and test) contains 113,893 color fundus images from 60,357 subjects and approximately 500 different sites with a heterogeneous ethnicity.

This is a machine-learning-ready glaucoma dataset using a balanced subset of standardized fundus images from the Rotterdam EyePACS AIROGS train set. This dataset is split into training, validation, and test folders which contain 2500, 270, and 500 fundus images in each class respectively. Each training set has a folder for each class: referable glaucoma (RG) and non-referable glaucoma (NRG). Three versions of the same dataset are available with different standardization strategies: RAW - Resizing the source image to 256x256 pixels PAD - Padding the source image to a square image and then resizing it to 256x256 pixels. This method preserves the aspect ratio but the resultant image contains less usable information. CROP - Cropping black background in the fundus image, pad the resultant image to create a square image, and then resize to 256x256 pixels. This method preserves the aspect ratio and the resultant image contains the most usable information.

This is an improved machine-learning-ready glaucoma dataset using a balanced subset of standardized fundus images from the Rotterdam EyePACS AIROGS [1] set. This dataset is split into training, validation, and test folders which contain 4000 (~84%), 385 (~8%), and 385 (~8%) fundus images in each class respectively. Each training set has a folder for each class: referable glaucoma (RG) and non-referable glaucoma (NRG). Improvements from v1: Increased the image dimensions from 256x256 pixels to 512x512 pixels Swapped the image file format from JPG to PNG Added 3000 images from the Rotterdam EyePACS AIROGS dev set Readjusted train/val/test split Improved sampling from source dataset Drawbacks of Rotterdam EyePACS AIROGS: One of the largest drawbacks of the original dataset is the accessibility of the dataset. The dataset requires a long download, a large storage space, it spans several folders, and it is not machine-learning-ready (it requires data processing and splitting). The dataset also contains raw fundus images in their original dimensions; these original images often contain a large amount of black background and the dimensions are too large for machine learning inputs. The proposed dataset addresses the aforementioned concerns by image sampling and image standardization to balance and reduce the dataset size respectively. Origin: The images in this dataset are sourced from the Rotterdam EyePACS AIROGS [1] dataset, which contains 113,893 color fundus images from 60,357 subjects and approximately 500 different sites with a heterogeneous ethnicity; this impressive dataset is over 60GB when compressed.
