each of the functions representing a local detail at a specific resolution level.
The multi-resolution representation has a pyramidal structure such that the
number of pixels in each detail image decreases at each coarser resolution
level. (Col. 4, ll. 18-27; col. 7, ll. 8-13.)
7. As shown in Figures 3b and 5, Vuylsteke teaches that the detail
images (31) are fed to pyramidal noise reduction unit (32) to pixel wise
attenuate them as a function of a locally estimated amount of relevant signal
content and in accordance with an estimated noise level. (Col. 7, ll. 24-32.)
8. In the Background of the Invention, Vuylsteke indicates that there
exists a well-known tradeoff between diagnostic image quality and patient
dose due to the presence of noise in the radiation source. (Col. 1, ll. 16-18.)
9. Further, Vuylsteke indicates that, ideally, filter parameters should be
adjusted to the local image statistics. (Col. 1, ll. 29-30.)
10. Additionally, Vuylsteke indicates that adaptive noise suppression is
known to have been achieved in the art by linearly combining all levels at
every pixel position, the weight coefficients being adapted to the local noise
statistics at every pixel. (Col. 2, ll. 15-18.)
PRINCIPLES OF LAW
1. ANTICIPATION
It is axiomatic that anticipation of a claim under § 102 can be found
only if the prior art reference discloses every element of the claim. See In re
King, 801 F.2d 1324, 1326, 231 USPQ 136, 138 (Fed. Cir. 1986) and
Lindemann Maschinenfabrik GMBH v. American Hoist & Derrick Co.,
730 F.2d 1452, 1458, 221 USPQ 481, 485 (Fed. Cir. 1984).
