1. Image reduction:
? Alternative line reduction
? Fractal linear reduction to reduce images to any smaller size
2. Use two images to perform image enlargement:
? Pixel replication
? Nearest enlargement
? Bilinear interpolation
? Bicubic interpolation
? Fractal linear expansion to expand images to any larger size
3. Perform negative image operation
? On gray images
? On color images(1. Image reduction.
