摘要
A global motion estimation-based time-domain filtering method and apparatus, and a storage medium. Said method comprises: acquiring a current frame image photographed by a photographing device (S101); on the basis of global image mean histograms in row and column directions, performing global motion estimation on the current frame image by using a reference frame image by means of a local image optimal matching algorithm to obtain global motion vectors in the row and column directions (S102); using the global motion vectors in the row and column directions to offset the reference frame image to obtain the offset reference frame image, and determining a time-domain filtering coefficient (S103); and filtering the current frame image according to the offset reference frame image and the time-domain filtering coefficient to obtain the filtered current frame image (S104).
