“…Sugimoto et al's metric in [11] uses only receiver-side information but extracts quantizer scale information from the bit stream along with two spatiotemporal image features from the baseband signal, which are integrated to express the overall quality using the weighted Minkowski metric. Sugimoto and Naito's metric in [12] is based on parametric analysis of the post-transmission coded bit stream, so it does not have access to the baseband signal (pixel level information) of the decoded video.…”

“…Sugimoto and Naito's metric in [12] is based on parametric analysis of the post-transmission coded bit stream, so it does not have access to the baseband signal (pixel level information) of the decoded video. These parameters are then used to calculate spatiotemporal image features to reflect coding artifacts which have been found to correlate with subjective quality in human perceptual experiments related to entertainment purposes such as IPTV and next generation DVD [11].…”

“…Sugimoto et al [314] proposes a hybrid no-reference metric combining bitstream-based feature with pixel-based features from the decoded bitstream. For the pixel-based features, the metric uses the average blockiness and flickering determined over all frames in the sequence, and as a bitstream-based feature it uses the average quantiser scale determined over all frames in the sequence.…”

Video quality metrics determine the visual quality of distorted video sequences by using prediction models based on objectively measurable features and are therefore an alternative to the time-consuming and costly subjective video quality assessment. In the conventional design approach to video quality metrics, however, the temporal nature of video is often considered only inadequately due to the use of temporal pooling in the prediction process. Moreover, this approach also often requires knowledge about the human visual system that is not readily or only partly available. In this thesis, I therefore propose a data driven design methodology using multi-way data analysis for the design of video quality metrics. This data driven design approach not only requires no detailed knowledge of the human visual system, but also allows for a proper consideration of the temporal nature of video by using a three-way prediction model, corresponding to the three-way structure of video. Using two simple example metrics, I demonstrate that this purely data driven approach not only outperforms video quality metrics in the state-of-the-art that are often highly optimised towards specific properties of the human visual system, but also that multi-way data analysis methods outperform the combination of two-way data analysis methods and temporal pooling.iii

Recopilar para avanzar. Hacer balance como medio de subsistencia. Fabricar listas como quien dibuja su alma. Soñar a Perec como quien baila con fantasmas. Evocar a Deleuze, la imagen rizomática, el recuerdo inaprensible, el pasado que se fuga por la chimenea. Esculpir el tiempo y dibujar su evanescencia. Ser postmodernos y referenciales. Pensar, como Idea Vilariño, en lo que ya no será, porque esa es a veces la mejor forma de reconocer lo que fue.Ya no será tiempo de tesis, siempre ligado al Gatv, que no es más que quienes formamos y han formado parte de él. De ellos son inseparables estos casi cinco años de doctorado, casi seis desde que el grupo me abrió las puertas y fui conociendo a los que estaban, a los que llegaron conmigo y a las sucesivas generaciones que he ido viendo pasar durante estos años. Este tiempo de tesis no habría sido posible sin ellos, desde José Manuel hasta todos los doctorandos y proyectandos del grupo:
