Abstract
A system and method for determining a region of interest in an image, characterized in that it comprises the following steps: a plurality of lines Li i=1, . . . , n formed by pixels is defined in the image; in each line Li, a plurality of segments Sj j=1, . . . , m constituted by pixels is defined; a luminance level NVG(Sj) is calculated for each segment Sj based on the luminance of the pixels constituting this segment Sj; depending on this luminance level NVG(Sj) the segment Sj is selected or excluded from the region of interest; and the region of interest is obtained by amalgamating all the segments selected for each line.
