Abstract

The main objective of this paper is a texture-based solution to the problem of acute stroke tissue recognition on computed tomography images. Our proposed method of early stroke indication was based on two fundamental steps: (i) segmentation of potential areas with distorted brain tissue (selection of regions of interest), and (ii) acute stroke tissue recognition by extracting and then classifying a set of well-differentiating features. The proposed solution used various numerical image descriptors determined in several image transformation domains: 2DFourier domain, polar 2D Fourier domain, and multiscale domains (i.e., wavelet, complex wavelet, and contourlet domain). The obtained results indicate the possibility of relatively effective detection of early stroke symptoms in CT images. Selected normal or pathological blocks were classified by LogitBoost with the accuracy close to 75% with the use of our adjusted cross-validation procedure.

Abstract in PolishArtykuł opisywał doskonaloną metodę automatycznej detekcji tkanki mózgowia objętej udarem niedokrwiennym na podstawie cech tekstury obrazów badań tomografii komputerowej. Przetestowane zostały dotychczas wykorzystywane cechy teksturowe oraz obliczone z użyciem falek kierunkowych. Wykorzystana została metoda walidacji krzyżowej leave-one-patient-out dostosowana do niezrównoważonych zbiorów. Uzyskano, z użyciem klasyfikatora LogitBoost, dokładność klasyfikacji regionów patologicznych i norm na poziomie 75%
