Attribute Topology (AT) is a simple and visual representation method of formal concept. By AT, the formal concept can be computed visually and parallel. Attribute partial ordered structure diagram (APOSD) is based on the partial order relationships in math and focus on the cover and inclusion among attributes. Although AT and APOSD have already achieved mutual transformation, the definition and characteristics...
Attribute Topology (AT) and Concept Lattice are both concept computing methods in Formal Concept Analysis (FCA). Both of them can get the all of the concept in formal context. This paper mainly talks about the mutual transformation of AT and Concept Lattice in order to make clear the relationships between the two important branches of FCA. The result is that AT is the subset of Concept Lattice and...
The improved bit-plane complexity segmentation (BPCS) steganography carries on different processings to different bit-planes, with setting high threshold value at the high bit-plane and low threshold value at the low. Not only provides good visual imperceptibility and data embedding capacity, this scheme also is capable of resisting the analysis of the whole complexity histogram. However, it still...
