In the world of massive uploaded videos, to be able to cover the content
of a video at a glance becomes a necessity since there is no enough time to
watch the whole video for an individual. Looking at frames of different scenes
in a video gives a brief idea of the content, when each different scene images
are listed to be checked by the user. In this study, an approach using various
color palettes is proposed to be able to detect the different scenes of a
video. In the proposed method, color histogram values of sequential frames
firstly are calculated. If the difference in the histogram values of the pair
frames in sequence is over a threshold value (percentage of change), scene
change is detected. In the experimental studies, 3-Bit RGB (Red Green Blue),
6-Bit RGB, 8-Bit RGB, 9-Bit RGB, 1-Bit Binary, 4-Bit Gray, and 8-Bit Gray
palettes are implemented over a list of video files and compared. In the comparisons
of palettes, accuracy, precision, recall, and F1-Score performance metrics are
used. In the performance accuracy controls, 6-Bit RGB color pallet with a
threshold level value of 35% has been experimented as the best of all.
