ABSTRACT:
A first filtering module filters actual pixel values in a first direction (e.g., vertically), and a second filtering module filters interpolated pixel values received from the first filtering module in a second direction (e.g., horizontally). Also, a third filtering module filters actual pixels in the second direction. A computation module is coupled to the first, second and, third filtering modules. The computation module generates quarter-sample interpolated pixel values. These values are based on combinations of pixel values selected from actual pixel values and interpolated pixel values received from the first, second and, third filtering modules.
