An Investigation Into A Least Squares Method For Image Registration, Ernest William Cordon
An Investigation Into A Least Squares Method For Image Registration, Ernest William Cordon
Retrospective Theses and Dissertations
One of the problems associated with the automatic image processing of satellite photographs such as weather maps is the need for image registration; that is, the fitting of a map that has some translational and rotational bias to a known data base. This paper investigates a least square method of image registration using an image that has been converted into a boundary map with a pixel representation 1 for land, -1 for water and zero for cloud pixels. A sampled correlation array is constructed by shifting the weather map to locations on a given grid, centered around a sampled correlation …

Realization Of A Fast Automatic Correlation Algorithm For Registration Of Satellite Images, John E. Kassak
Retrospective Theses and Dissertations
The requirement for a fast automated correlation algorithm for registration of satellite images is discussed. An overview of current registration techniques is presented indicating a correlator, matching binary maps compressed from the original imagery, may provide the required throughput when implemented with a dedicated hardware/processor. An actual registration problem utilizing GOES digitally processed imagery is chosen and defined. The realization of a fast correlator, matching image input data with sampled data base reference image data in real time is considered.
