Acoustic Quanta
This paper presents a novel approach to sound analysis and resynthesis based on Gabor wavelets. These wavelets are mathematically simple and computationally modest, and are well suited to musical applications. This paper outlines the principles and equations behind quanta. It then gives examples of their applications in analysis and synthesis, and presents results from implementation on the PC.

At the finest scale of our coarse-to-fine alignment strategy, we require an alignment technique which performs well given large tile sizes but a very small search radius. In this context, techniques such as our previously-described fast subpixel L2 alignment, or even simpler techniques such as phase correlation [Kuglin and Hines 1975] are outperformed by a well-implemented brute-force procedure...
متن کاملBurst photography for high dynamic range and low-light imagingn mobile cameras
Cell phone cameras have small apertures, which limits the number of photons they can gather, leading to noisy images in low light. They also have small sensor pixels, which limits the number of electrons each pixel can store, leading to limited dynamic range. We describe a computational photography pipeline that captures, aligns, and merges a burst of frames to reduce noise and increase dynamic...
