 reconstruction is perfect this will look like gaussian noise.
 
 It can be seen from the plots that the results of :ref:`omp` with two
-non-zero coefficients is a bit less biased than when keeping only one (the
-edges look less prominent). However, it is farther from the ground truth in
-Frobenius norm.
+non-zero coefficients is a bit less biased than when keeping only one

 The result of :ref:`least_angle_regression` is much more strongly biased: the
 difference is reminiscent of the local intensity value of the original image.
