Image Processing Demos:

• Linear Spatial Filtering
  

  

  
  In this demo, we explain how to apply linear spatial filtering to an image and give several examples. The effects of three example filters on the elvis image can be seen to the right by mousing over the corresponding masks.

• Histogram Equalization
  This demo describes a technique for enhancing contrast by adjusting image intensities according to its histogram.

• SVD Compression
  In this example, the singular value decomposition (SVD) is used to compress images. Application to a test image is shown in the animation, SVD_animation.gif.
