Comparing the algorithms for Shot Boundary Detection in Video.
- Comparing methods that use Color Histogram, Edges, and Wavelet.
-
Color Histogram
- Out of the 24-bit color, the upper 4 bits of each color are used to create a 12-bit color.
- Total of 2^12=4096 colors#quantization
- A significant change in the histogram indicates a boundary.
- Out of the 24-bit color, the upper 4 bits of each color are used to create a 12-bit color.
-
Edge Direction Histogram
- Creating a histogram using Edge Direction.
- Significant changes indicate a boundary.
- Creating a histogram using Edge Direction.
-
Wavelet
- Similar to the sibling of Fourier Transform.
-
As a result, the color histogram-based method is effective for movies, while the wavelet-based method is effective for natural scenes and sports footage.
-
However, it was challenging for music videos due to their intense movement and transitions.
