A method of stabilizing and registering a video image in multiple video fields of a video sequence provides accurate determination of the image change in magnification, rotation and translation between video fields, so that the video fields may be accurately corrected for these changes in the image in the video sequence. In a described embodiment, a key area of a key video field is selected which contains an image which it is desired to stabilize in a video sequence. The key area is subdivided into nested pixel blocks and the translation of each of the pixel blocks from the key video field to a new video field is determined as a precursor to determining change in magnification, rotation and translation of the image from the key video field to the new video field.

A computer based method of detecting and displaying rotational wind shear. Radial wind velocities within first and second adjacent gate sweeps produced by a radar system are detected in a predetermined geographic area, and are compared at points of equal radial distance from the radar system. The radial location of gate to gate wind shear at positions between the radar system and the boundary of the radar systems range are identified and compared to a predetermined threshold wind velocity value to determine the location of high priority gate to gate wind shear. The high priority gate to gate wind shear is then graphically displayed relative to its geographic location on a graphical representation of the predetermined geographic area. A computer based system for detecting and displaying rotational wind shear is also disclosed.
