Experiments with style transfer [2015]

Style transfer is the technique of recomposing images in the style of other images. These were mostly created using Justin Johnson’s code based on the paper by Gatys, Ecker, and Bethgedemonstrating a method for restyling images using convolutional neural networks. Instructions here, and more details here. A gallery with all of these and more style transfers can be viewed here.

World’s Tiniest Violin

Created by Design I/O, World’s Tiniest Violin is a ‘speed project’ that uses Google’s Project Soli – Alpha Dev Kit combined with the Wekinator machine learning tool and openFrameworks to detect small movements that look like someone playing a tiny violin and translate that to control the playback and volume of a violin solo.

The team used the Project Soli openFrameworks example provided with the ofxSoli addon and searched for the signal that seemed to correlate closest with the tiny violin gesture. In this case it was the fine displacement signal, which then they fed the delta of to Wekinator via OSC. Theo (Design I/O) then had to train Wekinator on what types of finger movements corresponded to playing the violin and which ones it should reject. So he recorded a few different finger movements and assigned the value of 1.0 on the slider. The slider to 0.0 and recorded gestures were then set which didn’t correspond: like pulling your hand away from the sensor, or just holding it there without moving your fingers. After a few minutes of recording these gestures, the ‘training’ was initiated and they were then able to send back an animated value ranging from 0.0 to 1.0 representing how much Theo’s hand looked like it was trying to play a tiny violin. The last step was to map that number to the volume of the violin sample that was being played back by the openFrameworks app.

06. Appraisal of a an Art .app with ANT

Posted on by

Theory Background

 

The walkthrough method is grounded in the principles of Actor-Network Theory (ANT), as a specific aspect of STS (science and technology studies). ANT foregrounds a relational ontology according to which sociocultural and technical processes are mutually shaping.

The core of this method involves the step-by-step observation and documentation of an app’s screens, features and flows of activity – slowing down the mundane actions and interactions that form part of normal app use in order to make them salient and therefore available for critical analysis. The researcher registers and logs into the app, mimics everyday use where possible and dis- continues or logs out while attending to technical aspects, such as the placement or num- ber of icons, as well as symbolic elements, like pictures and text.

Chosen Review

The app being reviewed here is from the art website ArtRabbit.

ANT Review

The revenues for the site relies mostly on advertising for events and exhibitions from professional galleries and art organizations. The promotion of individual artist to the site helps sell the advertising so that the target audience are mostly  either art lovers or art professionals. The main target of advertising for art organizations.

The gender bias aims to be neutral. In my opinion the design seems 60-40 % feminine-masculine design. I would guess they have decided upon a gender neutral tone for the site.

The design and fonts are modern, clean and hip.  The typography has been purposely constructed to feel gender neutral. It has a strong yet simple and clean layout. The feeling of space and whiteness is a modern design aesthetic

The Branding. Is so graphic design led clean and simple and easily to identify and remember the brand. I would say brand awareness is high. You will remember the logo and design aesthetic.

Going through the usage is of the .app is very easy u only have access to : openings , exhibition and events. All of the events in your area are shown on a mobile map.
You can explore the pin-points by clicking on each of them and going into detail on whats on offer. You will receive a brief summary of whats on offer and a link to the website for more information. U have 2 icons for to save favorites (a star) and to book mark ( an eye).

The use of icons. If you add a star to to something the site will remember this and send u details of all related starred events. It will remind u of the event as the event nears. An Eye events mean u have seen this event and it invites u to add a review of the event for the site. Social media icon U can instantly share events on social media. Map icon shows u where the event is on a google style map and gives u a route to the vent from where u are.

Overall opinion.  I would say this is a artists site primarily. You have the opportunity to advertise you own exhibitions and promote them. People can follow you. U can link instagram and websites into the app so u get further promotion. Linked closely to this are the professional galleries that want close associations with artists and also curators.

04. Swarm art Computing Appraisal

Posted on by

 

From its commercial games/film humble beginnings with craig Reynolds paper Flocks, Herds, and Schools: A Distributed Behavioral Model (http://www.cs.toronto.edu/~dt/siggraph97-course/cwr87/) the ideas of using swarm algorithms in art are growing and varied in there output. From the artwork of 2001 Leonel Moura who produced Swarm Paintings with a ant algorithm to the beautiful installation Diffusion Choir,(https://vimeo.com/187037469) the movements of the sculpture are perpetually evolving, driven by the flocking simulation.

The idea of emergence deriving from flocking algorithms is inherent in the algorithms developed for Stochastic diffusion search (J.M Bishop) 1989 and 1992 Ant colony optimization (Marco Dorigo). In art it was first seen in the artwork of 2001 Leonel Moura who produced Swarm Paintings with an ant algorithm. http://www.leonelmoura.com/index.php/robot-art/swarm-paintings/

In his book, Emergence: The Connected Lives of Ants, Cities and Software, Steven Johnson presents Emergence as an alternative way of understanding complex systems. A hierarchical, top-down system attempts to use a centralized decision-making process based on abstract rules to guide behavior. The emergent position looks at complex systems differently: a small number of rules that are processed by individual units are the best method of explaining the aggregate behavior. While a statistical analysis of an emergent system will lead to abstract outcomes. This system has an inherent relationship with Swarm intelligence (SI) that the collective behavior of decentralized, self-organized systems, natural or artificial.  A population of simple agents or boids interacting locally with one another and with their environment (The expression was introduced by Gerardo Beni and Jing).

If we look at the swarm art sister of cellular automata with swarm art (http://ieeexplore.ieee.org/document/7361206/) its a topic that Andy Lomas uses in his artworks which he calls Morphogenetic Creations. (https://www.youtube.com/watch?v=k7u2CVXzs2c). There are simularities with this work and Neri Oxman https://www.youtube.com/watch?v=CVa_IZVzUoc. Both use a mixture of cellular automata with swarm art algorithms.

Swarm art in architecture. The paper of swarm modeling by Carranza, Pablo Miranda and Paul Coates (https://www.generativeart.com/on/cic/2000/CARRANZA_COATES.HTM.) , Paul chooses swarms as a study case is the fascination of the simplicity of its mechanics and its complexity as a phenomenon. It describes the swarms understanding them as examples of sensori-motor intelligence. Another architect Arne Quinze uses curves, lines, colours and movement in his pieces. his woodstick structures provide a feeling of movement and fluidity, that combine to create a large frame structure. (https://www.dezeen.com/2008/12/09/the-sequence-by-arne-quinze/)

When we look at swarm interactive art that utilizes a proximity sensor such as the kinect the observer becomes a conductor of the art form and becomes far more immersed in the work. More connected to the work and more responsive. Great examples of this work are Daniel Rozin, “Penguins Mirror,” 2015 (https://vimeo.com/129674054) and the swarm wall by Michael Theodore (https://vimeo.com/45073818).

The psychology of swarm interactive art is an inherent behaviour of human urbanization. We like living in close proximity. We enjoy the human swarms at football matches as well as the group human interactions of dance and team events. Swarming behavior is part of our psychology as Dr Ian Couzin has been researching.(http://www.nytimes.com/2007/11/13/science/13traff.html).

The future of swarm art lies in more immersive experiences. Either in the real word or the virtual world. The idea of mobile interactive swarms in the real world will be the closest we can experience the true wonders of swarm art. The development process of 3d swarm art computing is very much tied to technology and how and what we can physically do. At the moment we don’t have any technology that can integrate into a entire swarm. We do have air drones and they have been used in previous installations the Faena Studio Drift 300 Drone Swarm: https://www.youtube.com/watch?v=mGmtId_ePmc but as yet they haven’t been used to this extent inside a installation venue. When air drones can be made to be insect size and can fly for greater times proper inside swarms will emerge.
