UR PRODUKTIONLundberg, Katarina January 2017 (has links)
När det är mörkt tycker jag om att gå hem. Det är oftast utifrån mina nattliga vandringar jag producerar, samlar och ser samband då jag i ensam tystnad möter nya rum och konstellationer som uppstår och försvinner i staden. Jag fotograferar till blivande målningar, filmar eller tar objekt från platser för att använda i mitt arbete. Denna text koncentrerar sig främst kring de platser jag ser på, tankar kring dem och hur de överförs till att bli måleri.

Objective measurement of video qualityGranström, Hugo January 2023 (has links)
Automatic video quality assessment has many potential use cases in today’s video-filledsociety, for example, when trying to find highlights in a video. This thesis studies the possibilityof extracting the best segments from a video automatically based on five selected metrics:sharpness, colorfulness, contrast, stability, and aesthetics. Multiple different methods from eachmetric category were compared against each other using datasets with subjective ratings ofimages from KADID-10k and videos from LIVE-Qualcomm. The best method from eachcategory was combined into a single video quality score. The combination was done through aweighted sum, obtained from a least-square fit on the subjective scores of a training dataset(KonViD-1k). The segment of a video with the highest average quality score was chosen as thehighlight. The video quality score achieved Spearman correlations of 0.67 and 0.7 whenevaluated on two validation datasets (KonViD-150k-B and LIVE-VQC). In conclusion, themetrics work well, but are currently too slow for the intended target platform (mobile devices)and thus future work should focus on improving their performance.
