KHTP (Kobayashi Hue & Tone 130 palette) Dataset

Dynamic Closest Color Warping to Sort and Compare Palettes

Geometric Computing Lab., School of Computing, KAIST
Presented at ACM SIGGRAPH 2021

1. Description

  • KHTP is a dataset to evaluate the palette pair sorting.
  • For each test palette, the naturalness and concurrency of the pair are measured.

2. Structure

2-1. Tree

/KHTP-interpolation%d-jitter%d
├──/KHTP-interpolation%d-jitter%d-csv : This includes test palette pair in format of csv.
│   ├── KHTP-p0.csv
│   ├── KHTP-p1.csv
│   ├── ...
│   └── KHTP-p99.csv
└──/KHTP-interpolation%d-jitter%d-image : This includes test palette pair's images.
    ├── KHTP-p0-0.png 		: image of the 1st palette of the first pair in shuffled order
  ├── KHTP-p0-0-sorted.png : image of the 1st palette of the first pair in sorted order
    ├── KHTP-p0-1.png 		: image of the 2nd palette of the first pair in shuffled order
  ├── KHTP-p0-1-sorted.png : image of the 2nd palette of the first pair in sorted order
    ├── ...
    ├── KHTP-p99-0.png 
  ├── KHTP-p99-0-sorted.png 
    ├── KHTP-p99-1.png 
    └── KHTP-p99-1-sorted.png

  • The name of each KHTP type follows KHTP-interpolation%d-jitter%d.

    parameter description
    interpolation interpolated color count
    jitter jittering offset

2-2. Structure of the CSV file

  • The name of each file follows KHTP-p%d.csv.

    parameter description
    p palette's no.

  • Each CSV file presents a test palette pair, and the order is shuffled.

  • A palette pair consists of two palettes P1 and P2.

    row no. description
    1 original order of hex color in the sorted P1
    2 shuffled hex colors of the P1
    3 original order of hex color in the sorted P2
    4 shuffled hex colors of the P2

  • Example:

    > cat example.csv

#e76c56	#cbd7e8	#b8bebd	#a2b324	#cd9a95	#f1b066	#129a2f	#7ebcd1	#e3bd1c	#2b9759

    • Sorted hexes of first palette:

      • #e76c56 #f1b066 #e3bd1c #a2b324 #129a2f #2b9759 #7ebcd1 #cbd7e8 #b8bebd #cd9a95

    • Sorted hexes of second palette:

      • #cf2e31 #f1b066 #e1c808 #aac61b #58ab2d #068654 #00939f #a5b8c7 #b8bebd #a09383
