Variable blend width compositing
-33 Abstract VARIABLE BLEND WIDTH COMPOSITING A method of producing an image with a blurred background (151) from an initial image (111) 5 and a depth map (112) identifying a foreground region (236) and a background region (237) of the image, said method comprising determining (670) an edge visibili...

| description | -33 Abstract VARIABLE BLEND WIDTH COMPOSITING A method of producing an image with a blurred background (151) from an initial image (111) 5 and a depth map (112) identifying a foreground region (236) and a background region (237) of the image, said method comprising determining (670) an edge visibility measure (671) for one edge (231) in the depth map (112) by comparing (820) a pixel value (233) in the foreground with a pixel value (234) in the background, said edge visibility measure (671) distinguishing between the foreground (236) and the background (237); applying (680) a spatially variable 10 blur to the depth map (112) to produce a compositing matte (681), dependent on the edge visibility measure (671); applying (530) a blur to the background region (521) of the depth map (112); and compositing (150) the blurred background image data (531) with the initial image (111) to produce the rendered image with the blurred background (151) A601 /7 AAAA2 ' Start 110 Captured image Obtain captured image 120 112 Obtain binary Binary depth map depth map (see Fig. 5) . 131 Segment and Background image blur Blurred background image background (see Fig. 6) 140 Edge visibility measure Generate Compositing matte clipped 141 compositing Clipped compositing matte matte 150 151 -Composite Bokeh image 1 image over blurred background 199 End Fig. 1 P066012 / 7464146_1 |
