Sports Video Classification Framework Using Enhanced Threshold Based Keyframe Selection Algorithm and Customized CNN on UCF101 and Sports1-M Dataset

Algorithm 3

Enhanced threshold-based frame difference for keyframe selection.

	input: cf
	output: kf
	CF: Candidate Frame
	KF: Keyframe
	FD: Frame Difference
	T: Threshold Value
	procedure keyframe
	Initialize KFi = CF1, CFn, j = 1
	for i = 2 to n − 1 do
	if(i ≤ n && i ≥ 2) then
	FDi = 1/mod(F)| Cfi−1(x, y) − Cfi(x, y) |//FrameDifference
	Else
	Stop
	end if
	if(FDi ≥ T) then
	KFj = FDi
	end if
