Colorization is a computer-assisted process of adding color to a

monochrome image or movie. The process typically involves

segmenting images into regions and tracking these regions across

image sequences. Neither of these tasks can be performed reliably in

practice; consequently, colorization requires considerable user

intervention and remains a tedious, time-consuming, and expensive

task.



In this paper we present a simple colorization method that requires

neither precise image segmentation, nor accurate region tracking.

Our method is based on a simple premise: neighboring pixels in

space-time that have similar intensities should have similar colors.

We formalize this premise using a quadratic cost function and obtain

an optimization problem that can be solved efficiently using standard

techniques. In our approach an artist only needs to annotate the

image with a few color scribbles, and the indicated colors are

automatically propagated in both space and time to produce a fully

colorized image or sequence. We demonstrate that high quality

colorizations of stills and movie clips may be obtained from a

relatively modest amount of user input.

There is diffrent software for adding colour into black & white films


In short i can tell you that each & evry frame has to be masked & then colour is applied .


every colur has its own mask..
