Oriented wavelet transform on a quincunx pyramid for image compression
This paper presents a new image coding technique based on oriented 1D multiscale decompositions on a quincunx sampling grid. A transform obtained by adapting the lifting steps of ...

Block-Based Methods for Image Retrieval Using Local Binary Patterns
In this paper, two block-based texture methods are proposed for content-based image retrieval (CBIR). The approaches use the Local Binary Pattern (LBP) texture feature as the sourc...

Analysis of limit cycle stability in a tap-changing transformer
The paper analyses the nature of limit cycles induced through the interaction of transformer tap changing and load dynamics. Linearization of a Poincar´e map is used to prove loc...
