If objects of all the classes derived from the same base class all need to draw themselves, the draw() function would most likely be declared:

Adjacent tracks are separated by _________.

A. sectors B. gaps C. pits D. heads

This problem is about graph signal inpainting via total variation regularization. Signal in- painting is the process of estimating missing signal values from available noisy measurements. Assume that the observed graph signal is y = [ y T1 y T2 ] T , where y 1 ? R M × 1 is known and y 2 = 0 ? R ( N ? M ) × 1 is missing or unknown. Now two cases are possible: the known part of the signal y 1 may be noisy or noiseless.

(a)



(b)

Hint: Use the method of Lagrange multipliers.

Note: The problem in the book has a small error. Above is the corrected version.
