Visibility computation is crucial for computer graphics from its very beginning. The first visibility algorithms aimed to determine visible lines or surfaces in a synthesized image of a 3D scene. Nowadays there is a plethora of visibility algorithms for various applications. The thesis proposes a taxonomy of visibility problems based on the dimension of the(More)
We present a novel <i>color-by-example</i> technique which combines image segmentation, patch-based sampling and probabilistic reasoning. This method is able to automate colorization when new color information is applied on the already designed black-and-white cartoon. Our technique is especially suitable for cartoons digitized from classical celluloid(More)
We introduce a novel colorization framework for old black-and-white cartoons which has been originally produced by a cel or paper based technology. In this case the dynamic part of the scene is represented by a set of outlined homogeneous regions that superimpose static background. To reduce a large amount of manual intervention we combine unsupervised(More)
We introduce a novel approach to video compression which is suitable for traditional outline-based cartoon animations. In this case the dynamic foreground consists of several homogeneous regions and the background is static textural image. For this drawing style we show how to recover hybrid representation where the background is stored as a single bitmap(More)
In this paper we discuss a challenging problem of applying novel color information into the old black-and-white cartoons. Thanks to possibility, which allows us to convert the original analogue material to the sequence of digital images, we are able to solve this task using methods of digital image-processing. Classical works from the history of cartoon(More)

This poster introduces a novel semi-automatic colorization framework which is suitable for cartoons originally shot in black-and-white on classical celluloid films. More specifically we focus especially on the cel or paper based cartoon making technology. In this case usually the background layer is a static image and only the dynamic foreground needs to be(More)
