C4L Image Dataset
=================
This is a collection of 2D and 3D images used for grayscale image processing tests. It includes at least 8 images of each of the following sizes:

* 256x256 - 65.5k pixels
* 512x512 - 262k pixels
* 1024x1024 - 1.05m pixels
* 1920x1080 - 2.07m pixels - 1080p or 'HD'
* 2560x1440 - 3.69m pixels - 1440p or '2K'
* 2560x1920 - 4.92m pixels - 5 MP camera photo
* 256x256x128 - 8.39m voxels

Each set contains a randomly generated image.

Conversion Notes
================
All images that were originally in color were converted to grayscale using Rec. 601:

```
0.299 R + 0.587 G + 0.114 B
```

Original images may be cropped and/or resized to fit into one of the predefined image sizes. All images are stored as uint8-PNG images. For some images this required rescaling the data.
