An approach to computer-supported cartooning

Joaquim S. Madeira, André Stork, Markus H. Groß
1996 The Visual Computer  
Two different system modules allow either manual coloring of images or computer-assisted automatic painting of an image sequence.  ...  This is achieved by using a shape-matching algorithm to evaluate the similarity of image regions and by performing an optimum region assignment to identify the corresponding ones and propagate the color  ...  The first author's stay at the Computer Graphics Center in Darmstadt is being supported by JNICT/CIENCIA scholarship BD/2205/92-IA.  ...

The Animation Transformer: Visual Correspondence via Segment Matching [article]

Evan Casey, Víctor Pérez, Zhuoru Li, Harry Teitelman, Nick Boyajian, Tim Pulver, Mike Manh, William Grisaitis
2021 arXiv   pre-print
AnT enables practical ML-assisted colorization for professional animation workflows and is publicly accessible as a creative tool in Cadmium.  ...  Visual correspondence is a fundamental building block on the way to building assistive tools for hand-drawn animation.  ...  Once it is converted to a uniform line drawing (also known as a clean line), artists colorize by clicking on each individual line enclosure (segment) with a uniform color and flood filling it with a color  ...

2013 Proceedings of the 26th annual ACM symposium on User interface software and technology - UIST '13  
We then display these lines over the model to guide its manual reproduction by the user on the drawing canvas. Finally, we use shape-matching to register the user's sketch with the model guides.  ...  Our drawing assistant provides guidance and feedback over a model photograph that the user reproduces on a virtual canvas (a).  ...  This work was funded in part by Autodesk (research and software donations) and by ANR-12-JS02-003-01 DRAO.  ...

Built into the computer are various commands to assist the designer in de- veloping a design: e@Line — This will draw a line hori- zontally or vertically. eConnect — By defining two points on the screen  ...  Pro- viding that there is no break in the out- line by using the paint or fill function of the computer, that area will be filled with the desired color using “fill” or “paint” function.  ... 

3D Shape Analysis for Archaeology [chapter]

Ayellet Tal
2014 Lecture Notes in Computer Science  
Finally, within restoration, we describe our results for digital completion of broken 3D shapes, for reconstruction of 3D shapes based on their line drawing illustrations, and for restoration of colors  ...  Archaeology is rapidly approaching an impasse in its ability to handle the overwhelming amount and complexity of the data generated by archaeological research.  ...  Colorization: Colorization traditionally refers to the computer-assisted process for adding color to black-and-white images and movies. For 3D models, colorization has hardly been explored.  ...

Region matching with proxy ellipses for coloring hand-drawn animations

Yoshihiro Kanamori
2012 SIGGRAPH Asia 2012 Technical Briefs on - SA '12  
In the production pipeline, manual coloring of line drawings is tedious and labor-intensive.  ...  We propose a method for accelerating the coloring step by matching corresponding regions in successive frames and propagating the same color to the regions.  ...  Our Region Matching Method Given frames of line drawings (bitmap images), we first extract regions by applying a seed fill algortihm.  ...

Visual conditioning for augmented-reality-assisted video conferencing

Onur G. Guleryuz, Antonius Kalker
2012 2012 IEEE 14th International Workshop on Multimedia Signal Processing (MMSP)  
Our method works by determining virtual backgrounds that match and highlight participant visuals and uses directional textures to hide segmentation artifacts due to noisy segmentation boundaries, missing  ...  Taking advantage of simple computations and look-up-tables, our work leads to fast, real-time implementations that can run on mobile and other computationally-limited platforms.  ...  The designed directional textures are motivated by the "contour-hatching" drawing technique and the designed backgrounds by the "cross-hatching" shading technique as well as harmonic colors [10], [9]  ...

Manual Rendering Techniques in Architecture

Ali Dashti Shafii, Babak Monir Abbasi, Shiva Jabari
2016 International Journal of Engineering and Technology  
Many clients are still wowed by hand drawn drawings. Hand rendering can soften drawings and even make computer generated images look more personal.  ...  Recently, though, due to rendering software for drawing a perspective and finalizing it, a growing number of young architects and designers just hop straight onto their computers and work their ideas out  ...  THE IMPORTANCE OF LINE DRAWING Line drawing is the first and superior requirement in architectural designing process.  ...
