Digital image processing refers to processing digital image by means of a digital computer. Digital image processing refers to processing digital image by means of a digital computer.

3. An image is digitized to convert it to a form which can be stored in a computer's memory or on some form of storage media such as a hard disk or CD-ROM. Once the image has been digitized, it can be operated upon by various image processing operations.

4. Image Processing :Operations  Image Compression  Image Enhancement and Restoration  Measurement Extraction

5. Basic Enhancement & Restoration Techniques   Unsharp masking   Noise suppression   Distortion suppression

6. Basic equation:F(x,y)=f(x,y)-f’(x,y) Figure Figure 1. Original 2. Mask 3. result

7. Noise Supression In the left picture there is some distortion due to noise during digitization process but the right picture is clear with the elimination of noise.
