Abstract

The invention provides an electronic image stabilization method based on multi-resolution gray projection. The electronic image stabilization method comprises the following steps of: (1), determining whether a foreground local motion object exists or not by utilizing a current down-sampling image and a reference image, thereby obtaining a global motion vector; (2), reserving active scanning movement of a vidicon itself while removing random jitter by filtration through a real-time particle filtering method; and (3), eliminating an adjacent-frame accumulative error by adopting a self-adaptive adjacent-frame compensation method through a variable reference frame.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an electronic image stabilization method based on multi-resolution grayscale projection. Background technique [0002] With the development of technology, all walks of life have higher and higher requirements for image processing to improve people's perception. There are several widely used algorithms in the current image processing field: grayscale projection algorithm, motion filtering algorithm based on particle filter, adjacent frame compensation method. [0003] The grayscale projection algorithm needs to perform grayscale mapping on each pixel in the image and perform related calculations, resulting in a large amount of computation; at the same time, when there are moving objects in the image, the grayscale projection method cannot detect moving objects, resulting in motion estimation accuracy. reduce. [0004] Among them, the motion filtering method based on par...
