“…This can result in long reconstruction times measured in minutes or hours. Recent developments make progress toward compressive video reconstruction [12][13][14][15][16][17][18], with emphasis on developing methods to reduce computational time [19,20]; however, in this paper we concentrate on compressive techniques that do not require computationally expensive reconstruction and are therefore able to provide near video frame rates.…”

“…However, signal reconstruction and sparse representation are designed as independent tasks in [7,8,28], and then, it has a negative impact in terms of consuming resources, since the sparse coefficient calculation has already been included in the process of dictionary learning. Zheng and Jacobs [11] presented a differencing method in order to take advantage of the spatial redundancy between neighboring frames, but it is only suitable for sequences that have small spatial changes. In [12], Ma et al proposed a modified approximate message passing algorithm to recover the undersampled videos, by using the 3D dual-tree complex wavelet transform with some correlation noise.…”

“…Stankovic [30] and Prades-Nebot et al [25] divided each frame into non-overlapping blocks and approximate each block by a linear combination of blocks in previously transmitted frames the CS decoding process. Zheng and Jacobs [36] proposed a video compressive sensing method using spatial domain sparsity, where key frames or reference frames are fully sampled and CS measurements are applied to the difference between the successive frames and the other frames. Xu et al [33] incorporated a user attention model with visual rhythm analysis in CS video processing which can automatically determine regions of interest.…”
