The wave kernel signature
WebWe introduce the Wave Kernel Signature (WKS) for characterizing points on non-rigid three-dimensional shapes. The WKS represents the average probability of measuring a quantum mechanical particle at a specific location. By letting vary the energy of the particle, the WKS encodes and separates information from various different Laplace eigenfrequencies. WebKernel Flow is here… Precision neuroscience has needed a hi-res tool that quickly and easily collects robust brain data at scale. After five years of development, we built Kernel Flow: …

WebJun 26, 2024 · This paper introduces a spectral analysis algorithm based on wave kernel signature. This shape signature was used for studying the shape of segmented ventricles from the brain images. Based on the shape signature, the study groups were classified as normal subjects and atrophy subjects. Webare the Wave Kernel Signature (WKS) and the Heat Kernal Signature (HKS). While these descriptors are robust to different surface dis-cretization, there is a lot of room for improvement making them more discriminative. This can been done successfully using neural networks to compute supervised descriptors. A very promising type

WebJul 1, 2024 · The Improved Wave Kernel signature (IWKS), which was introduced by Limberger and Wilson (2015), presents a different energy scaling from the WKS of Aubry et al. (2011). This scaling is the result of an investigation of how the eigenvalues of the shapes modify after these being deformed by non-rigid motions.
