Abstract (in Japanese) (See Japanese page) 
(in English) This report proposes a new image colorization algorithm using optimization. Introducing two assumptions
that the color value of the two neighbor pixels which have the very different gray value is the very different
and the color value of the two neighbor pixels which have the same gray value is the same, which is formulated as
the weighted least squares problem. Numerical examples show that the proposed algorithm colorizes a grayscale
image well using a small number of color pixels.
