As crowdsourcing gains popularity, organisations seek ways to systematically and reliably involve their workforce with data processing pipelines. Mobile crowdsourcing allows for opportunistic task executions and thus, potentially, for higher throughput. However, how to engage and to retain employees in enterprise crowdsourcing campaigns is still an open research topic. This ...

Understanding the perceptual impact of compression artifacts in video is one of the keys for designing better coding schemes and appropriate visual quality control chains. Although compression and transmission artifacts, such as blockiness, blurriness, and packet-loss, appear simultaneously in digital videos, traditionally they have been studied in isolation. In this ...

Multimedia experiences allow us to access other worlds, to live other people's stories, to communicate with or experience alternate realities. Different spaces, times or situations can be entered thanks to multimedia contents and systems, which coexist with our current reality, and are sometimes so vivid and engaging that we feel ...

Most automatic Quality of Experience (QoE) assessment models have so far aimed at predicting the QoE of a video as experienced by an average user, and solely based on perceptual characteristics of the video being viewed. The importance of other characteristics, such as those related to the video content being ...

Recognizing what makes an image aesthetically pleasing is crucial to the effectiveness of many multimedia systems. Several works have attempted to build image aesthetic appeal predictors, and created their own set of ground truth data for the purpose, either by using rated images from photo sharing websites, or by asking ...

Unobtrusive recognition of the user's mood is an essential capability for affect-adaptive systems. Mood is a subtle, long-term affective state, often misrecognized even by humans. The challenge to train a machine to recognize it from, for example, a video of the user, is significant, and already begins with the lack ...

Crowdsourcing gives researchers the opportunity to collect subjective data quickly, in the real-world, and from a very diverse pool of users. In a long-term study on image aesthetic appeal, we challenged the crowdsourced assessments with typical lab methodologies in order to identify and analyze the impact of crowdsourcing environment on ...

Crowdsourcing has the potential to address key challenges in multimedia research. Multimedia evaluation, annotation, retrieval and creation can be obtained at a low time and monetary cost from the contribution of large crowds and by leveraging human computation. In fact, the applicative frontiers of this potential are yet to be ...

Crowdsourcing has the potential to become a preferred tool to study image aesthetic appeal preferences of users. Nevertheless, some reliability issues still exist, partially due to the sometimes doubtful commitment of paid workers to perform the rating task properly. In this paper we compare the reliability in scoring image aesthetic ...

Research on Quality of Experience (QoE) heavily relies on subjective evaluations of media. An important aspect of QoE concerns modeling and quantifying the subjective notions of 'beauty' (aesthetic appeal) and 'something well-known' (content recognizability), which are both subject to cultural and social effects. Crowdsourcing, which allows employing people worldwide to ...

Providing a satisfactory visual experience is one of the main goals for present-day electronic multimedia devices. All the enabling technologies for storage, transmission, compression, rendering should preserve, and possibly enhance, the quality of the video signal; to do so, quality control mechanisms are required. These mechanisms rely on systems that ...

Reduced-reference systems can predict in real-time the perceived quality of images for digital broadcasting, only requiring that a limited set of features, extracted from the original undistorted signals, is transmitted together with the image data. This paper uses descriptors based on the color correlogram, analyzing the alterations in the color ...

This paper investigates how saliency obtained from eye-tracking data can be integrated into objective metrics for JPEG compressed images. The objective metrics used in this paper are both based on features, locally extracted from the images and serving as input to a neural network for the overall quality prediction. We ...

Reduced-reference paradigms are suitable for supporting real-time modeling of perceived quality, since they make use of salient features both from the target image and its original, undistorted version, without requiring the full original information. In this paper a reduced-reference system is proposed, based on a feature-based description of images which ...
