Directional Invariance of Co-occurrence Matrices within the Liver
2008
2008 International Conference on Biocomputation, Bioinformatics, and Biomedical Technologies
Preserved Fulltext
In this paper we analyze the directional invariance of Co-occurrence matrices for the purpose of reducing their runtime by reducing the number of directions analyzed without negatively affecting the quality ...
Co-occurrence matrices are one of three texture algorithms commonly used on Computed Tomography (CT) images. ...
Directions 1-4 are the four directions commonly used in 2D co-occurrence matrices while directions 5-13 are the additional nine directions used in 3D co-occurrence matrices. ...

Given that the calculation of the co-occurrence texture model is a computationally-intensive task, in this paper we investigate the usefulness of using all possible angles and all displacements for capturing ...
Then we calculated 16 co-occurrence matrices for each liver region corresponding to four directions (0°, 45°, 90°, 135°) and four displacements (1, 2, 4, and 8) as indicated in Figure 3 . ...
