Ensemble Convolution Neural Network for Robust Video Emotion Recognition Using Deep Semantics

Algorithm 1

Histogram difference for keyframe selection.

(1)	Extract the video frames (… )
(2)	Find the histogram difference between two adjacent frames (fj, fj+1)
(3)	Calculate M and SD of absolute difference
(4)	Compute threshold, TH
(5)	Compare the difference (d) with TH
	if the d > TH
	select it as a keyframe
	Else
	go to step no. 2.
(6)	Continue the process till the end of the video
