Your Task
You will first see a video in original quality:
After that, you see the same video in reduced quality:
Your Task:
- Rate the quality of the videos.
- Good quality is given if the surfaces of objects are smooth and easily recognisable.
- A video of bad quality has less recognisable surfaces.
- Rate the difference in quality between the original video and the reduced video.
- Even in the original video you might see areas that are not fully scanned (Areas are missing e.g. a roof). This should not influence your rating!
- In addition at the end of each video there will be a red letter in the top right corner. Memorize it and tick/check the corresponding box below your rating.
Further informations on the topic are at the end of the survey.
