Fig. 5From: Low storage space for compressive sensing: semi-tensor product approachComparison of the reconstructed images with different dimensions of measurement matrices. (OT-colon, M = 256, N = 512, ℓ 0-minimization with ρ = 0.8). Frame a is the original image; Frame b is the reconstructed image from the original in Frame a using the matrix Φ 256×512; Frame c is the reconstructed image using the matrix Φ 128×256; Frame d is the reconstructed image using the matrix Φ 64×128; Frame e is the reconstructed image using the matrix Φ 32×64; Frame f is the reconstructed image using the matrix Φ 16×32 Back to article page
