Function attribute_scene_complexity

Computes the scene complexity attribute in the given seqeunce

Scene complexity represents the level of randomness (entropy) in the frames and it was calculated as $e = \sum_{i = 0}^{255}b_i\log b_i$, where $b_i$ is the number of pixels with value equal to $i$.

Input:

• sequence (struct): An array of sequence structures.

Output:

• mean_val : mean value of scene complexity for the sequence

• val_val : variance of scene complexity for the sequence

• frames : scene complexity for each frame
