Ethereum Merge

Update: March 24,2022

Ethereum
The Merge

Eventually the current Ethereum Mainnet will "merge" with the beacon chain proof-of-stake system.
This will mark the end of proof-of-work for Ethereum, and the full transition to proof-of-stake.
This is planned to precede the roll out of shard chains.
We formerly referred to this as "the docking."
This upgrade represents the official switch to proof-of-stake consensus. This eliminates the need for energy-intensive mining, and instead secures the network using staked ether. A truly exciting step in realizing the Ethereum vision – more scalability, security, and sustainability.

Incorrect Labels in Global Wheat Head Dataset 2021

There are several incorrect labels in Global Wheat Head Dataset 2021. Some images are annotated in their original size. After that, the images are resized to final size (1024×1024 pixels). As the result, the bounding boxes are a little bit off.

Here is the list of affected images

To correct the annotation, the coordinates must be multiplied by a correction factor and shifted a little bit downward. Here is the comparison between original annotation (green) and corrected annotation (red).

Global Wheat Head Dataset 2021 Released

I believe that the entire dataset (including bounding box for test images) is released here: https://zenodo.org/record/5092309 1

This dataset is mentioned in the new paper “Global Wheat Head Dataset 2021 1” , in the “Code & Data Section”

I did a quick look, and I found that image filenames are changed.
