Morphological Operators for Image and Video Compression [PDF]
IEEE Transactions on Image Processing, 1996 This paper deals with the use of some morphological tools for image and video coding. Mathematical morphology can be considered as a shape-oriented approach to signal processing, and some of its features make it very useful for compression. Rather than describing a coding algorithm, the purpose of this paper is to describe some morphological tools that

The Spectrum of a Selfadjoint Compression of a Self-Adjoint Operator. [PDF]
Proceedings of the American Mathematical Society, 1970 The relation between the spectrum of a selfadjoint operator and the spectrum of its compression is investigated. In particular, we show that the compression of a selfadjoint operator is essentially selfadjoint if and only if the spectrum of the closure of the compression is contained in the closed convex hull of the spectrum of the operator.

Closedness and Adjoints of Products of Operators, and Compressions [PDF]
Integral Equations and Operator Theory, 2012 The authors reprove and slightly improve theorems of \textit{M. A. Nudelman} [Integral Equations Oper. Theory 70, No.~3, 301--305 (2011; Zbl 1248.47037)] and \textit{W. Stenger} [Bull. Am. Math. Soc. 74, 369--372 (1968; Zbl 0153.45105)] about compressions of maximal dissipative and self-adjoint operators to subspaces of finite codimension and discuss ...

Image compression by morphological operators
IEEE International Geoscience and Remote Sensing Symposium, 2003Image compression techniques generally rely on the results of information theory. A decorrelation of the signal followed by quantization and entropy coding of the information to transmit achieves image compression. Mathematical morphology can be considered a shape-oriented approach to signal processing and some of its features are useful for ...

Compressed Imaging With a Separable Sensing Operator
IEEE Signal Processing Letters, 2009Compressive imaging (CI) is a natural branch of compressed sensing (CS). Although a number of CI implementations have started to appear, the design of efficient CI system still remains a challenging problem. One of the main difficulties in implementing CI is that it involves huge amounts of data, which has far-reaching implications for the complexity ...

Operators over Compressed Integer Encodings
2010 XXIX International Conference of the Chilean Computer Science Society, 2010Compact representation of integer values is a key feature for data compression. A compressed representation allows us to store more integers within less space, and therefore, to work in faster hierarchies of memory. Adaptive searching yields to compressed representations of integers.

Multi-Objective Operator for Optimal Compression and De-Compression of Random Signals
2018 IEEE International Work Conference on Bioinspired Intelligence (IWOBI), 2018 New multi-objective operators of random signals are presented in this paper. The new operators improve, under a unrestrictive condition, the performance of known techniques: the generalized Karhunen-Loeve transform, the transform considered by Brillinger and the generalized Brillinger-like transform.

Index compression method with compressed mode Boolean operators
[1991] Proceedings. Data Compression Conference, 2002Summary form only given. This paper describes an algorithm which provides a high degree of compression and at the same time allows logical Boolean operations to be performed directly on the compressed representation of the index. An inverted index of English text using this technique has only 20% to 25% of the size of the original text.

Operations on compressed image data
Proceedings DCC '95 Data Compression Conference, 2002A formal framework of directly processing the encoded data is presented. Image operations which can be directly and efficiently applied on run-length encoded data are identified. The FSM and attributed FSM models are used to describe these operations.

Exploring the Possibility of Operating in the Compressed Domain
2004Data compression in caches has been studied from the performance and energy consumption points of view. In this paper, we study the possible benefits of operating with compressed operands. Operating in the compressed domain (i.e., executing instructions with compressed operands) as far as possible can offer several advantages.
