We introduce a modification of the nonlinear morphological correlation for optical rotation-invariant pattern recognition. The high selectivity of the morphological correlation is conserved compared with standard linear correlation. The operation performs the common morphological correlation by extraction of the information by means of a circular-harmonic component of a reference. In spite of s...

<span>Wireless capsule endoscopy (WCE) is a significant modern technique for observing the whole gastroenterological tract to diagnose various diseases like bleeding, ulcer, tumor, Crohn's disease, polyps etc in non-invasive manner. However, it will make substantial onus physicians human oversight errors with time consumption manual checking of vast amount image frames. These problems mot...

We present a generalization of the concept of Convex Sets, based on the Morphological Closing operation, and study some of its properties. We also deene Extreme Points of such Generalized Convex Sets, which generalize the notion of Extreme Points of Convex Sets. Moreover, we apply the above notions to skeleton redundancy removal, and present an algorithm for obtaining an Error-Free Skeleton rep...

A study is made to detect human eye from a color face image (in RGB space) using Harris corner detector and Sobel edge operator. Morphological operation like dilation and erosion are also applied to make the edge of the eyes sharp and prominent. This study is found to yield 90.47% eye detection rate which is comparable with the same obtained by other standard algorithm. Keywords-RGB color image...

⎯An adaptive algorithm for removing false ridges, bridges and filling gaps in binary fingerprint images based on morphological operations is presented. A novel procedure for structuring elements design based on the specific fingerprint characteristic is described. Using the images from FVC2000 database, we have compared our method proposed here with the approach proposed by other ones. The Expe...

In this work, the statistical behavior of a special type of morphological operation, the space-varying opening, is analyzed and investigated. The maior distinction between the space-invariant mor-

In the paper the implementation aspects of mathematical morphology based on a new formalization of the window operation is presented. The proposed technique called the Reverse Window Operation (RWO) can also be applied to adaptive morphological operations. In order to reduce the control complexity an algorithm is proposed, which uses a region-based parameter modiication for the structuring elem...
