149 *Filter Masks.* The filter masks to be discussed are Filter\_Mask, High
150 Edge Variance Mask (Hev\_Mask), Flat\_Mask, Flat\_Mask2
152 - Filter\_Mask: Indicates whether the edge is a true edge or an
171 the tested samples and set Filter\_Mask to zero. Otherwise,
172 Filter\_Mask is set to 1 and the tested samples are to be filtered.
174 - Hev\_Mask: Used to identify edges with large change in pixel values
177 If ABS(p1-p0) \> thresh OR ABS(p1-p0) \> thresh, then Hev\_Mask = 1,
178 else Hev\_Mask = 0.
180 - Flat\_Mask: Considered when Filter\_Length \>= 6. Indicates whether
185 Flat\_Mask = 1 when the following conditions are true:
191 Otherwise, Flat\_Mask = 0.
237 depending on High Variance Edge Mask (Hev\_Mask). Rough outline of
239 - Hev\_Mask = 1  only q0 and p0 are filtered.
242 - Hev\_Mask = 0  q0, q1, p0 and p1 are filtered.
