Add Annotation Task Instruction Text and Informed Consent Form

[huangziwei]

As the Annotation Task is quite straight forward, I'd suggest putting the instruction text and informed consent form at one place, so that one-click will lead users to the task.

• Call the task: "Lesion annotation for diabetic retinopathy (DR)" @huangziwei
• Remove the "Welcome", just use the task title
• Spell out the lesion types in addition to using their abbreviations

Instructions: Your task is to annotate lesions related to Diabetic Retinopathy on fundus images. By moving the mouse over the image, you get a magnified cutout of the image in the small window below. All images are from patients with DR of grade 0 ("no DR"), grade 1 ("mild DR") and grade 2 ("moderate DR"). For best contrast, you may need to adjust the brightness of your monitor to maximal.

To mark a lesion, select the type of lesion on the right. You can annotate microaneurysms (MA), hemorraghes (HE), exudates (EX), soft exudates (SE), artefacts or other lesions. You add a lesion marker to the image by clicking on the image. You can also highlight or remove a lesion again by clikcing the respective button in the panel in the top right.

Make sure you work carefully and annotate all lesions that are present. When you are done with an image, click "submit". The annotations will be saved.

If you need to interrupt a session, we will load the images and corresponding annotations that you have already submitted.

Information about the study: Your annotations will be saved on a secure server in the EU and will be used to assess the quality of the disease prediction of an AI algorithm. If you have additional questions, do not hestiate to ask. No personal information will be disclosed at any time. Please check "consent" below if you agree to these terms.

For this task, are the images sorted in any way?

[kdjoumessi]

I think we can just merge the images and send them randomly to be annotated without any specification regarding the actual label

The show button is actually a bit redundant. You can just click on the dot to highlight it. It's more intuitive this way, but sometime it's a little bit difficult to do as the dots are quite small. That's why I still kept the show button for now.
