Published: — with international search report (Art. 21(3)) (54) Title: IMAGE PROCESSING METHOD, APPARATUS AND COMPUTER PROGRAM (57) : The present invention provides a novel algorithm for salience Input Colour detection based on a dual rail antagonistic structure to predict where people look Image (9 in images in a free-viewing condition. Furthermore, the proposed algorithm can be effectively applied to both still and moving images in visual media without any parameter tuning in real-time. 52.31 Obtain negative luminance image Y u from Fig. 1 S2 - 1 52.1 Blur Ito obtain 522, Obtain luminance image Y o from Generate colour opponencies F, , 53.1 Calculate Dominant Edge Orientation LS41 3,1 S25 v W O 20 18/ 142110 Al Calculate Calculate Minimum Ratio Minumum Ratio Matrix M s Matrix M s Derive M s Derive Ms ID- S28 Calculate Luminance Conspicuity Map C 0 Derive RG BY features 53.2 S3.3-. • Derive Colour Conspicuity Map C s S5 Se 7 S4 2 Compute a, features S43 S4.4 ).
