In this paper, we describe a method to manipulate a paintbrush for a painting robot. The robot has multi-fingered hands and a stereo vision system. It grasps a paintbrush with its own hand and paints a picture on a canvas. Because a brush is deformable, adequate control of a paintbrush is a challenging task. It is necessary to develop several manipulation methods with feedback control using bot...

Context. In recent years, a new generation of large-scale imaging surveys have probed wide field regions for the first time around some nearby galaxies in an unprecedentedly low surface-brightness regime (∼28.0−29.0 mag arcsec −2 ). This provides chance to discover very faint dwarf satellites by means systematic visual inspection these public deep images. Aims. this paper, we report results sur...

In this paper we describe the problem of painter classification, and propose a novel approach based on deep convolutional autoencoder neural networks. While previous approaches relied on image processing and manual feature extraction from paintings, our approach operates on the raw pixel level, without any preprocessing or manual feature extraction. We first train a deep convolutional autoencod...

Hallucinatory inspiration Visual migrainous hallucinations have provided inspiration for others. Charles Dodgson, better known as Lewis Carroll, is known to have suffered from migraine and is thought to have used his migrainous disturbances of body image as inspiration for Alice's Adventures in Wonderland.'0 Atkinson and Appenzeller described a patient who had migraine who painted her complex v...

A new scheme for painterly rendering (NPR) has been developed. This scheme is based on visual perception, in particular the multi-scale line/edge representation in the visual cortex. The Amateur Painter (TAP) is the user interface on top of the rendering scheme. It allows to (semi)automatically create paintings from photographs, with different types of brush strokes and colour manipulations. In...

Consider the following game between two players, Builder and Painter. Builder draws edges one at a time and Painter colours them, in either red or blue, as each appears. Builder’s aim is to force Painter to draw a monochromatic copy of a fixed graph G. The minimum number of edges which Builder must draw, regardless of Painter’s strategy, in order to guarantee that this happens is known as the o...
