Lightness and Brightness Match under Colored Illuminants with Special Illuminant Gradients

H. Kawamura, M. Date, T. Yamakawa, T. Kojima, M. Miyao, and A. Kojima

Proc. of AIC (International Colour Association) 2016 Interim Meeting, pp. 417–420, Santiago, Chile, October 2016.

This paper reports an investigation of perceived colors under colored illuminants with spatial illuminant gradients. In performed experiments, two types of illuminant distribution were used; in one the illuminant strength changes suddenly at the center of an image and in the other the strength changes linearly throughout the right and left side of the image. Subjects were asked to match the test patch area to identify the same luminance as the reference one (called the brightness match) or to match the area to be cut from the same piece of paper as the reference one (called the lightness match) under white illuminant or reddish illuminant. The results showed that the response of the subjects in the brightness match is affected by the luminance of the test patch area; however, with the lightness match the response is slightly more stable than the brightness match. This tendency occurred in both illuminant distribution patterns. When using a reddish illuminant, the response of the subjects was lower than that for the white illuminant.

Collapse of the Hierarchy of Constant-depth Exact Quantum Circuits

Y. Takahashi and S. Tani

Computational Complexity, Vol. 25, No. 4, pp. 849–881, December 2016.

We show that there exists a constant-depth polynomial-size quantum circuit for the OR function. We apply this circuit to constructing a constant-depth quantum circuit for the threshold function. Moreover, we show that there exists a classically hard problem that can be solved by a constant-depth quantum circuit with gates for the quantum Fourier transform.
