Stereo image normalization: If a set of image points of an image are normalized, it means

i. The means of all image points are at [0,0]

ii. The average distance between all points and (0,0) should be 1.414 =sqrt(2)

Given a set of normalized image points: p(1),p(2),..,p(9). The distance between p(i) to [0,0] is r(i). Such that [r(1),r(2),..,r(9)]=[r1, 1.597, 0.65038, 1.1405, 1.5725, 0.42936, 1.7521, 2.082, 1.4283] and also p(1)=[a,0.82627]'

Find square(a) to the nearest 3 decimal points.
