Regulated morphological operations [PDF]

Pattern Recognition, 1999
In this paper regulated morphological operations are defined by extending the fitting interpretation of the ordinary morphological operations. The defined operations have a controllable strictness, and so they are less sensitive to noise and small intrusions or protrusions on the boundaries of shapes.

A Fault Diagnosis Method Based on Improved Adaptive Filtering and Joint Distribution Adaptation

IEEE Access, 2020
In the real environment of industrial equipment, the vibration signals of essential components show deviations due to the fault and noise. Notably, the noise in the signal will interfere with the diagnosis process of the signal and reduce the accuracy of

An Improved Feature Set for Hyperspectral Image Classification: Harmonic Analysis Optimized by Multiscale Guided Filter

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Effective features derived from an original hyperspectral image (HSI) are quite important to improve the classification performance. An improved feature set, namely HGFM, is constructed by integrating harmonic analysis (HA) optimized by a multiscale ...

Discretization of morphological operators [PDF]

Journal of Visual Communication and Image Representation, 1992
This paper presents a comprehensive theory of discretization of images, image operators, and image functionals in mathematical morphology. The procedure of image discretization discussed here consists of two steps: (i) the definition of a sequence of discrete images obtained by sampling the original continuous image on grids with finer and finer mesh ...

On the Discretization of Morphological Operators

Journal of Visual Communication and Image Representation, 1997
We present new results on the problem of morphologically sampling binary images and image operators, thus enhancing the morphological sampling theory of Heijmans and Toet. These include sampling composite operators and approximating continuous translation invariant erosions, openings, and closings by discrete erosions, openings, and closings ...

Optic cup segmentation using adaptive threshold and morphological image processing

Communications in Science and Technology, 2019
Glaucoma is a chronic optic neuropathy. It was predicted that people with bilateral blindness caused by glaucoma will increase each year. Hence, computer-aided diagnosis of glaucoma was proposed to assist ophthalmologist to conduct a fast and accurate ...
