Spectral characteristics and motion-compensated restoration of composite frames
1Dept. of Electr. Eng. and Comput. Sci., California Univ., Berkeley, CA.
Abstract:
The practice of superimposing the fields of a frame is applied in various fields, for example, thermographic and biomedical imaging. The pictures obtained in this way, which are termed composite frames, are severely degraded if the scene's objects are not perfectly still. The restoration of composite frames affected by motion-induced blurring requires the ability to estimate the field displacement from composite frames. The frequency domain analysis of composite frames proposed in the paper suggests a displacement estimation technique of a phase-correlation type that can be applied to composite frames.
