Key-Frame Detection and Super-Resolution of Hyperspectral Video via Sparse-Based Cumulative Tensor Factorization

Algorithm 1

CTCF of third-order tensor.

	Input: original 3D cumulative tensor new tensor
	Step 1: new tensor is added in the time dimension and is obtained
	Step 2: decompose by CP factorization
	Step 3: update by (19), with and are fixed
	Step 4: update by (27), with and are fixed
	Step 5: update by (28), with and are fixed
	Step 6: estimate by updated , and
	Output: approximation of updated cumulative tensor
