We have discussed that the co-occurrence frequency image (CFI) defined based on the co-occurrence frequency histogram of the gray value of an image has a potential to introduce a new scheme for image feature extraction. This paper proposes a couple of filters for image enhancements of such as sharpening and smoothing filters. These filters are very similar to but quite different from those whic...

This paper investigates the impact of word frequency and pronunciation talent on proficient speakers’ second language (L2) production variability/similarity. The data analysed stem from a corpus of quasi-spontaneous conversations between native speakers of German and English. Within-speaker production similarity was established through a comparison of amplitude envelope signals for word tokens ...

This paper addresses a newly discovered security threat named Frequency of Occurrence Analysis (FOA) attack in searchmetics password authentication scheme. A countermeasure technique that utilises Metaheuristic Randomisation Algorithm (MRA) is proposed to address the FOA attack. The proposed Algorithm is presented and an offline FOA attack simulation tool is developed to verify the effectivenes...
