Type-Based Amortised Heap-Space Analysis
Abstract. We present a type system for a compile-time analysis of heapspace requirements of Java style object-oriented programs with explicit deallocation. Our system is based on a...

Quaternion wavelets for image analysis and processing
Using the concepts of two-dimensional Hilbert transform and analytic signal, we construct a new quaternion wavelet transform (QWT). The QWT forms a tight frame and can be efficien...

The fractional Hilbert transform and dual-tree Gabor-like wavelet analysis
We provide an amplitude-phase representation of the dual-tree complex wavelet transform by extending the fixed quadrature relationship of the dual-tree wavelets to arbitrary phas...

Event-Based Performance Analysis
Understanding performance and related issues in a complex system requires analyzing where and why the program spends its resources. In a reactive system such as a interactive appl...
