Interactive processing: Geometry manipulation
Robert G. Clapp
Header manipulation for regularization, registration and quality control is often a time-consuming
task with 3-D datasets.
These manipulation tasks are often performed multiple times before achieving the desired
each requiring a large amount of data to be read in with very few operations
performed on each byte read.
The problem can be made more tractable by reading in a random subset of the headers.
Operations such as rotating, windowing, and gridding can then be performed interactively.
With each processing step a record is created. These records can then
be used to process the entire dataset, requiring only a single read and write of
