Compressive Video Sampling With Approximate Message Passing Decoding

Abstract: In this paper, we apply compressed sensing to video compression. Compressed sensing (CS) techniques exploit the observation that one needs much fewer random measurements than given by the Shannon-Nyquist sampling theory to recover an object if this object is compressible (i.e., sparse in the spatial domain or in a transform domain). In the CS framework, we can achieve sensing, compression and denoising simultaneously. We propose a fast and simple online encoding by application of pseudo-random downsampling of … Show more

“…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. Liu et al presented a motion-aware decoding method [13] for compressively sampled videos and a maximum frame rate video acquisition framework was proposed in [14].…”

“…One kind of methods performs joint reconstruction of sub-video sequences. e.g., Ma et al [4] apply a modification of the approximate message passing algorithm and propose incorporating 3-D dualtree complex wavelet transform during reconstruction. Li et al [5] recover video cubes by minimizing TV norm of the pixelwise discrete cosine transform (DCT) coefficients along the temporal direction.…”
