CLIC is a dataset for the Challenge on Learned Image Compression 2020 lossy image compression track. These images contain a mix of the professional and mobile datasets used to train and benchmark rate-distortion performance. The dataset contains both RGB and grayscale images. This may require special handling if a grayscale image is processed as a 1 channel Tensor and a 3 channel Tensor is expected.

This dataset does NOT contain the data from the P-Frame challenge (YUV image frames).
