Real-Time Facial Expression Recognition System for Video Big Sensor Data Security Application

Algorithm 1

Rule for image sieving.

	Input: image similarities after ranking in sequence , similarity reference value , the number of images in sequence , images , images , the number , similarity between and , and flag parameter .
	Output: the starting point where the peak image appears , The ending point where the peak image appears .
