Figure 4: (a) Original Artificial synthetic image with Gaussian noise ( 𝑚 = 0 , 𝜎 = 0 . 0 2 ). (b) Segmentation using the Sine-Sinc model ( 𝜆 = 1 5 0 ). (c) Segmentation using the proposed model ( 𝜆 = 1 5 0 , 𝛿 = 0 . 2 ). (d) Original brain MR image with Gaussian noise ( 𝑚 = 0 , 𝜎 = 0 . 0 0 5 ). (e) Segmentation using the Sine-Sinc model ( 𝜆 = 1 5 0 ). (f) Segmentation using the proposed model ( 𝜆 = 1 5 0 , 𝛿 = 0 . 2 ).
