This paper presents a novel image binarization method that can deal with degradations such as shadows, nonuniform illumination, low-contrast, large signal-dependent noise, smear and strain. A pre-processing procedure based on morphological operations is first applied to suppress light/dark structures connected to image border. A novel binarization concept based on difference of gamma functions ...

The paper focuses on composing of discrete information units (items) into information complexes in hypertext systems. We consider basic operations (analysis, comparison, approximation, aggregation), combinatorial models (multicriteria ranking, knapsack problem with compatibility of items, multiple choice problem, morphological clique problem). Combinatorial information design on the base of mor...

This paper provides a novel descriptive and theoretical account for the ‘down-play’ mood marker ge in Mandarin Chinese. One essential property that is not covered by previous studies is its clitic status. Incorporating and enhancing Yang’s (2001) clitic treatment of numeral-less classifiers, I propose a morphosyntactic analysis that identifies the morphological-template for the mood marker ge −...

This paper describes an efficient framework for the extraction of a brain tumor from magnetic resonance (MR) images. Before the segmentation process, a median filter is used to filter the image. Then, the morphological gradient is computed and added to the filtered image for intensity enhancement. After the enhancement process, the thresholding value is calculated using the mean and the standar...

Discrete morphological operations with line segments are notoriously hard to implement. In this paper we study different possible implementations of the line structuring element, compare them, and examine their rotation and translation invariance in the continuous-domain sense. That is, we are interested in obtaining a morphological operator that is invariant to rotations and translations of th...

We present a digit-serial architecture for gray-scale morphological operations that operate on radix-2 redundant numbers. We present new implementations for a redundant number adder and a maximum unit that are used in the morphological dilation unit. These new designs have areas comparable to 2's complement implementations but have significantly smaller latencies.

A new framework which extends the concepts of soft mathematical morphology into fuzzy sets is presented. Images can be considered as arrays of fuzzy singletons on the Cartesian grid. Based on this notion the definitions for the basic fuzzy soft morphological operations are derived. Compatibility with binary soft mathematical morphology as well as the algebraic properties of fuzzy soft operation...

This paper proposes a new cost-effective architecture for mathematical morphology named Partial-Result-Reuse (PRR) architecture. For a lot of real-time applications of mathematical morphology, the hardware implementation is necessary; however, the hardware cost of almost existing morphology architectures is too high when dealing with large structuring elements. With partial-resultreuse concept ...

In a morphological lexicon, each entry combines a lemma with a specific inflection class, often defined by a set of inflection rules. Therefore, such lexica usually give a satisfying account of inflectional operations. Derivational information, however, is usually badly covered. In this paper we introduce a novel approach for enriching morphological lexica with derivational links between entrie...
