Figure 7From: Subspace weighted ℓ2,1 minimization for sparse signal recoveryRobustness of SW ℓ 2,1 -SVD to the confidence interval. (a) 90% confidence interval; (b) 99.9% confidence interval; (c) 99.99% confidence interval. The data window size is 32. Asterisk-solid curve: ℓ1-SVD; square-dash curve: SW ℓ2,1-SVD; triangle-up: true spacing.Back to article page
