Collect at least six gray-scale images that contain the following features:

• a collection of small objects
• a collection of large objects
• directional (oriented) features
• fine texture
• coarse texture
• geometrical shapes
• human faces
• smooth features
• sharp edges
• periodic patterns

You may select a few photos from your own photo album. Limit synthesized images to one or two in the collection. Limit images borrowed from web sites to one or two in the collection. A given image may contain more than one of the features listed above.

If you collect color images, convert them to gray-scale images.

For the purposes of further lab exercises, note that MATLAB can read images in tiff, gif, jpeg, bmp, ras, ppm, pgm, and a few other file formats. For more details, enter MATLAB (including the Image Processing Toolbox) and type in "help imread".
