Palette Corpus

Corpus created for the task of obatining the color palette from an image.

Characteristics

Corpus formed by 15579 images and their associated color palettes of size 8.

• The images are sized to 128 by 128 and they don't conserve its original aspect ratio. Therefore, they are distorted.
• The palettes are saved in image form, being images of 8 by 1. These palettes correspond to the means obtained when clustering the pixels of the images in eight groups by the conventional c-means algorithm.

Structure

The source images are stored in the folder corpus/images following the naming convention image-{n}.png where n is in the range [1, 15579].

The palettes are stored in the folder corpus/palettes following the naming convention palette-{n}.png where n is in the range [1, 15579] and means that this palette corresponds to the image image-{n}.png.

Sources

This corpus was created from the images provided by:

• 102 Category Flower Dataset
• The Oxford-IIIT Pet Dataset

The palettes were obtained using the Makefile located in the corpus folder. By performing $ make on this folder, the source images are downloaded, scaled to 128 by 128 and analyzed to obtain their palettes. The palettes are stored as images.

Requirements

For being able to regenerate this corpus, it's required:

• macOS 12.0 or higher (Intel)
