  1. Color-based texture mapping Isaac Perez Brennan Schmidt

  2. Motivation • Tediousness and labor cost for manga artists • Interesting way to convert a color image to texturized grayscale image • Looks cool

  3. Goal • Produce a textured image based on color differences • Preserve quality of image (luminance, borders)

  4. Our method • Converted from RGB to Lab • Split image into different segments based on a,b values • Used K-means to cluster colors into a feasible amount of textures(we use 10) • Map pixel from texture image to input imagewhile taking into account luminosity

  5. Obstacles • Image segmentation (EDISON) • Displaying edges • Too few textures • Texture size : Image size • Finding a good luminosity threshold (black/white)

  6. Preliminary results

  7. More preliminary results

  8. Good results

  9. More better results

  10. More better results

  11. Poor results

  12. More poor results

  13. Ongoing work • Luminance detection • Inserting edges • More/finer textures
