Rotation-invariant features based on steerable transforms with an application to distributed image classification
In this paper, we propose a new rotation-invariant image retrieval system based on steerable pyramids and the concept of angular alignment across scales. First, we define energy-b...

Fast indexing for image retrieval based on local appearance with re-ranking
This paper describes an approach to retrieve images containing specific objects, scenes or buildings. The image content is captured by a set of local features. More precisely, we ...

Enhanced leakage reduction Technique by gate replacement
Input vector control (IVC) technique utilizes the stack effect in CMOS circuit to apply the minimum leakage vector (MLV) to the circuit at the sleep mode to reduce leakage. Additi...

Coinductive Type Systems for Object-Oriented Languages
We propose a novel approach based on coinductive logic to specify type systems of programming languages. The approach consists in encoding programs in Horn formulas which are inter...
