METHOD AND APPARATUS FOR PROCESSING A VIDEO CONTENT BASED ON CONFIDENCE-AWARE GUIDED VIDEO FILTERING AND CORRESPONDING COMPUTER READABLE PROGRAM PRODUCT AND COMPUTER READABLE STORAGE MEDIUM
METHOD AND APPARATUS FOR PROCESSING A VIDEO CONTENT BASED ON CONFIDENCE-AWARE GUIDED VIDEO FILTERING AND CORRESPONDING COMPUTER READABLE PROGRAM PRODUCT AND COMPUTER READABLE STORAGE MEDIUM
A method includes:- computing a linear regression model based on a confidence-aware guided image filtering algorithm over a spatio-temporal set of windows (ωt,k) comprising a first spatial window of a first frame (t) and at least one second spatial window of at least one second frame (t-2, t-1, t+1, t+2), the first and at least one second frames being neighboring frames of a video content comprising temporally successive frames, all windows of the spatio-temporal set of windows containing a same pixel with index k;- computing a filtered value (pt,k) for the pixel with index k in the first frame (t) by applying the computed linear regression model to the spatio-temporal set of windows (ωt,k).The present disclosure also relates to the corresponding apparatus, computer readable program product and computer readable storage medium.
