Gabor filter bank has been successfully used for false positive reduction problem and the discrimination of benign and malignant masses in breast cancer detection. However, a generic Gabor filter bank is not adapted to multi-orientation and multi-scale texture micro-patterns present in the regions of interest (ROIs) of mammograms. There are two main optimization concerns: how many filters should be in a Gabor filter band and what should be their parameters.

The present study focused on the allelopathic
effects of the aqueous and methanol extracts of
Mesembryanthemum forsskalii Hochst. ex Boiss.
on germination and seedling growth of Malva
parviflora and Plantago ovata. M. forsskaliii was
collected from Al-Jouf area, Saudia Arabia. The
dried shoot system of M. fosskalii was used to
prepare water and methanol extracts with different
concentrations (25, 50, 75 and 100%) and distilled
water as the control. The results showed that the
aqueous and methanol extracts of M. forsskalii
