چکیده
The aim of the study is application of Triangular Prism Method (TPM) algorithm in computer assisted Papanicolaou smears analysis that is useful in cervical cancer screening. The TPM algorithm allows estimation of the FD (fractal dimension) for optical density of cell nuclei. Selection of the local FD for green color channel gives efficient separation between both cell nuclei classes. Proposed algorithm (Tiled TPM) improves separation by the fractal based estimation using larger area of the cell nuclei. Streszczenie. W artykule zaproponowano nowy algorytm estymacji wymiaru fraktalnego dla obiektów nieregularnych, takich jak jądra komórek bazujący na metodzie pryzm trójkątnych (TPM). Kafelkowy algorytm pryzm trójkątnych pozwala na estymację wymiaru fraktalnego dla większego pola powierzchni obiektu oraz pozwala na estymację lokalnych wymiarów fraktalnych dla małych skal. (Estymacja wymiaru fraktalnego z wykorzystaniem kafelkowej metody pryzm trójkątnych dla nieprostokątnych obiektów biologicznych)

Direct Estimation of the Fractal Dimensions of a Fracture Surface of Rock
A direct determination of the fractal dimensions of a fracture surface is essential for a better understanding of its complete topographic characteristics. In this paper, a laser profilometer is employed to measure the topography of a rock’s fracture surface. With the use of the triangular prism surface area and projective covering methods, the resultant data set enables us to directly determin...
متن کاملAn Adaptive Segmentation Method Using Fractal Dimension and Wavelet Transform
In analyzing a signal, especially a non-stationary signal, it is often necessary the desired signal to be segmented into small epochs. Segmentation can be performed by splitting the signal at time instances where signal amplitude or frequency change. In this paper, the signal is initially decomposed into signals with different frequency bands using wavelet transform. Then, fractal dimension of ...

متن کاملFractal Descriptors of Texture Images Based on the Triangular Prism Dimension
This work presents a novel descriptor for texture images based on fractal geometry and its application to image analysis. The descriptors are provided by estimating the triangular prism fractal dimension under different scales with a weight exponential parameter, followed by dimensionality reduction using Karhunen-Loève transform. The efficiency of the proposed descriptors is tested on two well...
