Android Meterial Design-Defining Shadows and Clipping Views (define shadow and cropping Views)-(4) Material Design introduces deep UI elements. It helps users understand the relative importance of each element and focus on what they are doing. A view (control), represented by the elevation of the Z attribute, determines the size of its shadow. A view with a higher Z value has a larger shadow. Views only cast shadows on the Z = 0 plane; they are not p

. Visually, the lower the destruction of a pixel, the higher its similarity to neighboring pixels. It is assumed that the degree of destruction of a seam is defined as the sum of the degree of destruction of the contained loudness. Design algorithms to find the seams with the lowest degree of disruption. Analyze the time complexity of the algorithm. It is simple to find the seams with the lowest degree of destruction, C[i,j] record the minimum degree of disruption of the seam to the current pi
