Figure 4From: Automatic movie restoration based on wave atom transform and nonparametric modelThe examples of wave atoms. The first row shows two wave atoms with different directions and scales. The second row shows their frequency responses. The corresponding labels are μ a =(3,6,3,0,0), μ b =(4,10,5,0,0), μ c =(3,1,6,0,0), μ d =(4,1,10,0,0).Back to article page
