Study Material for Photoshop Filters

Final Year Project Jing Luo

• A summary of four years’ graphic

experience

• Upgrade from a practice-based level to

a solid theoritical one

• A proposal from Mr Erkki Rämö to be a learning material

What’s inside

• Basic theories of image processing

• Four main filters groups: Blur, Noise, Sharpen, Special Effects

• Special filters theories and performs them in Matlab

• Java eLearning Application

What’s special

• Visual highlight instead of step-by-step guide

• Filter-cross as well as filter-self

comparison

• Theoretical upgrade based on practical represent

• Java eLearning application as a good

supplement and enhancement

Example

Typical Filters 1

• Blur Filters:

- Gaussian Blur

-Radial Blur

-Smart Blur

-Motion Blur

-Lens Blur

• Noise Filters:

- Add Noise -Dust & Scratches -Median

Typical Filters 2

• Sharpen Filters:

-Sharpen, Sharpen

Edges, Sharpen More

-Unsharp Mask

• Special Effects: -Distort Filters

-Liquify

Blur Filters with Matlab
