Fig. 1. (a) Experiment setup of the proposed method. P1, P2 are polarizers, and R1, R2 are retarders. (b) and (c) 4 × 4 Mueller matrix and Dep index images in the water with a 45 NTU turbidity.
Fig. 2. (a)–(d) Intensity images in the water with 30.0 NTU, 36.2 NTU, 41.0 NTU, and 50.0 NTU turbidity, respectively; (e) intensity and Dep variation of (a)–(d) along the colored lines.
Fig. 3. (a) Four measured m00(x, y) images at 30.0 NTU, 36.2 NTU, 41.0 NTU, and 50.0 NTU; (b)–(e) fitting results of backscattering intensity as a function of Dep values at 30.0 NTU, 36.2 NTU, 41.0 NTU, and 50.0 NTU, respectively.
Fig. 4. (a) Intensity image; (b) recovered image with the proposed descattering method; (c) and (d) the zoomed-in view of the region of interest in (a) and (b) marked out with red rectangle; (e) the intensity value variations of (a) and (b) along the colored lines.
