Takaaki Harada and Rei Kawakami who had many precious opinions enjoyed in creating this paper. Moreover, I say gratitude also to you of the Ikeuchi laboratory who had you cooperate in order to advance research deeply, at this place. Abstract A number of methods have been proposed to separate a color signal into its components: illumination spectral power(More)
The hot-phonon bottleneck effect in lead-halide perovskites (APbX3) prolongs the cooling period of hot charge carriers, an effect that could be used in the next-generation photovoltaics devices. Using ultrafast optical characterization and first-principle calculations, four kinds of lead-halide perovskites (A=FA+/MA+/Cs+, X=I-/Br-) are compared in this(More)
To model indoor scene realistically is a crucial and challenging problem. Indoor scene has a large number of three-dimensional range data and spatial restrictions in two-dimensional photographing, as well as inevitable specularities in certain parts. In this paper we intend to deal with such a problem. Principally, our method use three-dimensional (3D)(More)
