This paper presents a new method for detecting power disturbances in power distribution systems. The proposed method is based on Mathematical Morphology and operates by initially converting the vector signal into a matrix. The mean value of each row of the new matrix is calculated and then compared with the mean value of the normal signal in order to find the time location of any disturbances. The...
One of the primary tasks of videoframes processing of digital videostreams is to quantify the geometric structure of moving objects, in order to extract information from videostreams frames. In this paper we purpose a recursive algorithms that are based on morphological conditional dilation and conditional erosion operations. Practical implementation of purposed algorithms on real-time video sequences...
By analyzing the numerical characteristics of impulse noise images, in order to resolve spreading-noise problem resulted from dilating and eroding images base on mathematical morphology, an algorithm of dilating and eroding color impulse noise images based on mathematical morphology is proposed. The result of the experiment demonstrates that the new algorithm has same effect as traditional algorithm...
The principle and testing method of waste wood based panel connectors detecting system based on X-ray are introduced in this paper. In order to fix the shortcomings of small rightness, low contrast, slow gray change and serious noise pollution which X-ray image suffers from, the detecting image of waste wood-based panel connectors was processed by using the method of mathematical morphology. In this...
In applications, morphological operations such as dilation and erosion are executed consecutively for a number of times. Direct use of the existing MATLAB functions for this task is time consuming. To accelerate such repeated dilations and erosions, improving measures are proposed. Binary image pixels are categorized into open feature pixels, closed feature pixels, and background pixels. By introducing...
A fast algorithm for local maximum and minimum filters is presented by Marcel van Herk, utilizing separability and recursive algorithms. In this paper, we put forward another improved algorithm based on Marcel van Herk's research. The new algorithm makes the comparison for each pixel in two auxiliary spaces without utilizing the original image space with the purpose of reducing the calculation for...
Homotopic morphological image processing software solution is developed for detection of hair cracks in PCB, which cannot be seen by naked eye. The proposed software solution is implemented using basic morphological operations like dilation, erosion, opening, closing, hit-miss transform, thinning, thickening skeletonizing and pruning. The software solution also performs image enhancement operations...
