Abstract METHOD, SYSTEM AND APPARATUS FOR DETERMINING A PROPERTY OF AN IMAGE 5 A method of determining a property of an image (176) captured by a camera (127), is disclosed. Vanishing points (320, 330, 340) in the image (176). Each pixel of the image (176) is associated with one or more of the vanishing points (320, 330, 340) based on an orientation of the image gradient at the pixel. The image is partitioned into a set of regions associated with a pair of the determined vanishing points based on the vanishing point associations for pixels in 10 the image (176). Boundaries of the regions are aligned with the associated vanishing points. For at least one of the plurality of regions, a confidence value is determined for the property of the image based on pixels in the region. The property of the image is determined for one or more pixels within the image (176) based on the confidence value. 77R6694v1 -4 /14 200 Start 205 Receive image210 Determine vanishing points Associate pixels with vanishing points based on pixel edge orientation I __ 230 Determine image regions (e.g. oriented BSP tree) based on pixel associations Determine confidence value of image property (e.g. surface orientation) per region based on pixels in region Determine image property (e.g. surface orientation) per pixel based on region confidence values End Fig. 2 7786854v1(P083045_FigsAs Filed) |
