We describe a painting machine and associated algorithms. Our modified industrial robot works with visual feedback and applies acrylic paint from a repository to a canvas until the created painting resembles a given input image or scene. The color differences between canvas and input are used to direct the application of new strokes. We present two optimization-based algorithms that place such ...

Introduction: Lesions in multiple sclerosis (MS) brain images are known to affect automated image registration and segmentation. Improved registration of MS brains has been demonstrated, by prior in-painting of lesions with white matter (WM) signal intensity (SI) derived from neighboring voxels [1]. Here we present an alternative fully-automated approach using the whole-brain histogram and imag...

This paper introduces a novel approach to in-painting where the identity of the object to remove or change is preserved and accounted for at inference time: Exemplar GANs (ExGANs). ExGANs are a type of conditional GAN that utilize exemplar information to produce high-quality, personalized in-painting results. We propose using exemplar information in the form of a reference image of the region t...

Expressionist Painting: City Landscape City Landscape depicts a nonrepresentational scene.8 A sense of entrapment (or a means of escape) is felt as the applied and colorful paint appears to leak out from the central part of the support. Loosely constructed geometric shapes recall a rock-like surface, which enclose and frame the color within and assist the eye inward toward the colorful scene. E...

Graphic artists have a wide variety of applications to use for digital painting. Although each application has its own solution to enhance the user experience, most of them rely on the same standard feature; a single brush, which is completely dependent on user input for location. Although this is required for a fully controlled painting process, making small changes on this feature yields unpr...

background and objectives: painting workshops are part of the woodwork (carpentry) industry in which despite advances in technology, the work force fulfills most of the roles in the production process. since such manual activities are often performed with awkward postures due to lack of workers’ awareness and inappropriate design of tools and working conditions, ergonomic assessment of work env...

Hyperspectral imaging is a promising non-invasive method for applications in conservation of painting. With its ability to capture both spatial and spectral information which relates to physical characteristics of materials, the identification of pigments and its spatial distribution across the painting is now possible. In this work, The Scream (1893) by Edvard Munch is acquired using a hypersp...

Implicit painting is a non-photorealistic rendering method for painting implicitly represented CSG solids. The method is based on the fact that when a difference equation is applied to a set of particles these particles will move in 3D space. We view the motion of the particles as the motion of the hands of several painters and the trajectories of the particles as long unbroken brush strokes, o...

In the case of illumination and view direction changes, the ability to accurately detect the Regions of Interest (ROI) is important for robust recognition. In this paper, we propose a stroke-based semi-automatic ROI detection algorithm using adaptive thresholding and a Hough-transform method for in-situ painting recognition. The proposed algorithm handles both simple and complicated texture pai...

The present paper is primarily concerned with modeling complex turbulent wall-bounded flow in spray-painting processes by using a commercial CFD code. Computational results of turbulent channel flow with low Reynolds numbers are compared with DNS data in order to obtain the performance of turbulence models and near wall treatments. The realizable k-ε model with the nonequilibrium wall function ...
