This repo contains all the codes of Digital Image Processing class.
Scripts in this repo needs to be executed with MATLAB. Adjustment is needed for GNU Octave.

| 17 | spatial_filter_scalingtransform.m | Experiment on different scaling transform parameters for edge detection and enhancement. |
| 18 | spatial_filter_scalingtransform1.m | Same function as file above but only scale transform positive numbers to expose more edge. |
| 19 | spatial_filter_clipping.m | Same function as file above but use clipping instead of scaling transform to expose more edge. |
