Query by Image Content

Please take about 1/2 hour and try out IBM's query by image content (QBIC) demonstration. It will show you about searching and matching approaches for multimedia (image collections with text).

Try both browsing and focused search. You might look for beach scenes, or images with babies, or cities.

Please send a paragraph summary of your experiences. Be sure to try each of the 4 types of search covered; under Graphical Methods try both Color Percentages and Color Layout (be patient with this - they will redo it using Java). For each type of image you are looking for, indicate which approach worked best.

HyperCard Stacks

• Launch the HyperCard Player from On Guard. From the Home stack, click on What is Hypercard? and go through each of the cards. Please explain by email to the instructor: how buttons relate to anchors, how cards relate to nodes, and some of the support provided for multimedia.
• Go to the File menu, Open Stack, follow the dialog boxes to Desktop,
  then to Assignments, then to CS4984, then to Stacks. Inside that,
  work through the cards in each of the following stacks:
  
  
  • Your Tour of HyperCard folder, stack HyperCard Tour. Tell the instructor your favorite animation, how a stack is like index cards, what you like about backgrounds, and what animal the horn sounds like.
  • Practice stack --- tell the instructor what these cards are good for.
  • HyperCard Help folder (skim). In the HyperCard Help stack, look at the topic Working with Graphics and read What are Paint graphics? --- tell the instructor if HyperCard supports bit-mapped images. Under the topic Browsing and finding information look over the first 8 topics and tell the instructor how you might open MacWrite from HyperCard. In the Apple Event Primer stack read and very briefly tell the instructor how you can communicate with an application on another Mac.
  • HyperCard Stacks folder, Graph Maker stack --- which chart do you prefer?
  • HyperCard Stacks folder, Audio Help stack --- what frequency is supported with Best sound quality?
  • More Stacks folder, Background Art stack --- which background do you prefer?
