Kojiro Tanaka, Yuichi Kato, Akito Mizuno, Masahiko Mikawa, Makoto, Fujisawa

TL;DR
This paper presents a new method for dynamically displaying grass colors on urban green space displays by objectively mapping grass length to color scales, enhancing landscape harmony.
Contribution
The paper introduces an objective grass color scale setting procedure based on image processing and outdoor experiments, improving upon previous subjective methods.
Findings
Color scale corresponds to grass length based on viewpoint
Grass animation display effectively uses the new color scale
Outdoor experiments validate the mapping accuracy
Abstract
Recently, public displays such as liquid crystal displays (LCDs) are often used in urban green spaces, however, the display devices can spoil green landscape of urban green spaces because they look like artificial materials. We previously proposed a green landscape-friendly grass animation display method by controlling a pixel-by-pixel grass color dynamically. The grass color can be changed by moving a green grass length in yellow grass, and the grass animation display can play simple animations using grayscale images. In the previous research, the color scale was mapped to the green grass length subjectively, however, this method has not achieved displaying the grass colors corresponding to the color scale based on objective evaluations. Here, we introduce a dynamic grass color scale display technique based on a grass length. In this paper, we developed a grass color scale setting…
