Abstrakt
Understanding the saliency of keyframes in short casual/home-made videos containing redundant information is an important step towards the design of successful keyframe selection and summarization techniques for such videos. Therefore, we present an extensive user study focusing on saliency of keyframes in such short redundant videos.
In our study, more than 200 users annotated 32 videos, altogether selecting more than 20.000 keyframes. We present the description of the user study, the utilized annotation tool and we discuss the results.
We provide also a preliminary comparison of several popular keyframe selection techniques using the ground truth derived from the annotations.
