The checkerboard and phantom synthetic images consist of simple geometric shapes with sharp edges and uniform regions. Use these images to test your image processing algorithms. You can add synthetic noise to pristine images to test how an algorithm responds to various types of noise.
checkerboard | Create checkerboard image |
phantom | Create head phantom image |
imnoise | Add noise to image |
Noise refers to random error in pixel values acquired during image acquisition or transmission. Removing noise can improve image quality.
