Computer-Generated Sand Mixtures and Sand-based Images
Ryan A. Subong, Alma Jean D. Subong

TL;DR
This paper demonstrates a software algorithm that creates realistic sand mixture images from photographs and effectively converts digital images into sand-based visuals, maintaining content while altering texture.
Contribution
The paper introduces a novel algorithm for generating sand mixture images and converting digital images into sand-based visuals, verified through visual comparison and content preservation.
Findings
Generated sand mixtures resemble real ones in shade and color
The algorithm maintains image content during conversion
Generated textures are rougher with higher contrast
Abstract
This paper aims to verify the effectiveness of the software implementation of the proposed algorithm in creating computer-generated images of sand mixtures using a photograph of sand as an input and its effectiveness in converting digital pictures into sand-based images out of the mixtures it generated. The method of this paper is to visually compare the photographed image of the actual mixtures to its computer-generated counterpart to verify if the mixture generation produces results as expected and compare the computer-generated sand-based images with its source to verify image reproduction maintains same image content. The results of the mixture comparison shows that the actual and the computer-generated ones have similar overall shade and color. Still, the generated one has a rougher texture and higher contrast due to the method of inheriting visual features by pixel, not by…
