%X Nonlinear magnify can zoom in objects with global context. A nonlinear mapping function based on spherical geometry model is used and nonlinear image magnify can be achieved by this mapping function in image transform. For better viewing and to avoid distortion in the center of the viewing area, linear transform and nonlinear transform are combined. The results verify that it is an effective way to magnify image with keeping both local detail and global context.
