# COCO 2017 for Image Colorizaion |
|
|
## Dataset Summary |
|
|
[COCO (Common Objects in Context)](https://cocodataset.org/) is a large-scale object detection, segmentation, and captioning dataset. It includes complex, everyday scenes with common objects in their natural context. This dataset is a version of the COCO 2017 dataset, specifically processed and cleaned for image colorization tasks. It contains the images from the original dataset but they have been resized and center cropped to 224x224. It is further filtered to remove grayscale images, heavily filtered images, and other artifacts not suitable for training a natural colorization model. |

|
## Dataset structure |
|
|
The dataset contains the following field **`image`**, containing a color image. There are two splits: |
|
|
- Train split |
|
|
- Validation split |
|
|
|
|
|
**Note:** All original annotations (including bounding boxes, segmentations, and captions) have been **removed** from this version of the dataset, as they are not required for image colorization tasks. During training, the grayscale version of the image can be generated on-the-fly from the color image. |
|
|
|
|
|
The final number of images in the dataset after filtering are **103,273** in the train split, compared to the original **118,287** images and **4016** in the validation split, compared to the original **5000** images. |
|
|
|
|
|
## Curation Rationale |
|
|
This dataset was curated with the goal of training deep learning models to convert grayscale images into realistic color images, and advancing the state of the art in image colorization tasks. Since there are no dedicated datasets for image colorization, this dataset can be very helpful in such task. Existing datasets like [nickpai/coco2017-colorization](https://huggingface.co/datasets/nickpai/coco2017-colorization) have many black & white, heavily filtered, and other images not suitable for image colorization tasks. |
