SPECKLE SUPPRESSION AND ANALYSIS FOR SYNTHETIC APERTURE RADAR IMAGES
收藏 引用
OPTICAL ENGINEERING 1986年 第5期25卷 636-643页
作者: LEE, JS Naval Research Laboratory (United States)
Speckle appearing in synthetic aperture radar (SAR) images is generated by coherent interference of radar echoes from target scatters. Basically, speckle noise has the nature of a multiplicative noise. In this paper p... 详细信息

Advanced algorithms and Architectures for Signal Processing I 1986
作者: Duel-Hallen, Alexandra Heegard, Chris School of Electrical Engineering Cornell University IthacaNew York14853 United States
Delayed Decision Feedback Sequence Estimation (DDFSE) is a new signal processing algorithm for the detection of signals in the presence of noise'. This paper describes the role of DDFSE in digital recording. The p... 详细信息

INFLUENCE OF NONUNIFORMITY ON INFRARED FOCAL PLANE ARRAY PERFORMANCE
收藏 引用
OPTICAL ENGINEERING 1985年 第5期24卷 855-862页
作者: MILTON, AF BARONE, FR KRUER, MR USN RES LAB ELECTRO OPT TECHNOL BRANCH WASHINGTON DC 20375 USA
It is well known that detector response nonuniformity results in pattern noise with staring sensors that is a severe problem in the infrared due to the low intrinsic contrast of IR imagery. The pattern noise can be co... 详细信息

COHERENT OPTICAL-PATTERN RECOGNITION - A REVIEW
收藏 引用
OPTICAL ENGINEERING 1985年 第1期24卷 26-32页
作者: CASASENT, D Carnegie-Mellon University (United States)
Recent progress in coherent optical pattern recognition is reviewed. Emphasis is given to techniques for multiclass distortion-invariant pattern recognition. Real-time and practical architectures and algorithms are de... 详细信息

PERFORMANCE ANALYSIS AND SIZE OPTIMIZATION OF FOCAL PLANES FOR POINT-SOURCE tracking ALGORITHM APPLICATIONS
收藏 引用
OPTICAL ENGINEERING 1984年 第2期23卷 167-176页
作者: GROSSMAN, SB EMMONS, RB Lockheed Palo Alto Research Laboratories (United States)
A number of applications require the precise tracking or position estimation of an object unresolved in the system optics. This paper evaluates several one-dimensional interpolation algorithms (odd N-point centroids, ... 详细信息

OPTICAL ENGINEERING 1984年 第6期23卷 716-720页
作者: CASASENT, D ROZZI, W FETTERLY, D GEN DYNAM POMONA DIV PONOMA CA 91769 USA
Synthetic discriminant functions (SDFs) allow distortion invariance to be achieved in optical correlators, thus making such systems more practical. The synthesis of four different types of SDFs is reviewed. Their perf... 详细信息

Architectures and algorithms for Digital Image Processing 1983
作者: Danielsson, P.E. Tanimoto, S. Department of Electrical Engineering Linkoping University LinkopingS-581 83 Sweden
Several useful algorithms in image processing involve the spreading of a certain pixel state over large areas and distances. Very often this is a kind of growth from a "seed" conditioned by a binary ... 详细信息
