Green AI: An empirical study

In this work, we look at the intersection of Sustainable Software Engineering and AI engineering known as Green AI. AI computing is rapidly becoming more expensive, calling for a change in design philosophy. We consider both training and inference of neural networks used for image vision; to reveal energy-efficient practices in an exploratory...

Projector Systems to Control the Material Perception of an Object

The appearance of an object or scene is determined by factors like the material, the lights, the geometry, the position of the observer, and the surroundings.<br/>Changes in these factors can be simulated using a projector-camera setup.<br/>Other research focuses on changing the appearance from the perspective of the projector, or on projector...

Towards Real-Time Object Removal and Inpainting Through A Diminished Reality Application For Smartphones

Diminished reality (DR) is an extension of augmented reality (AR) in which real objects are concealed, removed, or replaced. State of the art DR implementations are written and evaluated on desktop platforms, and those which are aimed at smartphones use auxiliary data or hardware for image completion. This paper introduces a DR app for Android...

Using Multiple On-Site Markers to Create Large-Scale Augmented Reality Experiences on Smartphones

Augmented Reality (AR) tracking for mobile devices is not realiable in environments where large virtual content, such as an entire virtual building, is to be displayed to the user. This paper presents a study on how multiple on-site markers can be used to better align the virtual scene to the real-world environment to improve large-scale AR...

Coherent Stylization for Stereoscopic Augmented Reality

In this paper, a method is proposed for stylizing stereoscopic augmented reality, while attempting to retain temporal and visual coherence. By tracking an AR marker and estimating a disparity map from stereo images, world positions of anchor points are tracked across frames and images, in order to move them with the scene. Additionally, the...

Achieving Perceptual Consistency of Contrast in Physical Images Viewed at Different Distances

According to the Contrast Sensitivity Function, the contrast of different spatial frequency elements of an image will be seen differently depending on distance. We propose a method for compensating for these differences by acting on an image's frequency representation and manipulating the magnitudes of the individual wave functions composing the...
