Multi-Level Canonical Correlation Analysis for Standard-Dose PET Image Estimation

Multi-Level Canonical Correlation Analysis for Standard-Dose PET Image Estimation Abstract: Positron emission tomography (PET) images are widely used in many clinical applications, such as tumor detection and brain disorder diagnosis. To obtain PET images of diagnostic quality, a sufficient amount of radioactive tracer has to be injected into a living body, which will inevitably increase […]


Quaternion Collaborative and Sparse Representation With Application to Color Face Recognition

Quaternion  Collaborative  and  Sparse  Representation  With  Application  to Color Face Recognition  Abstract: Collaborative representation-based classification (CRC) and sparse RC (SRC) have recently achieved great success in face recognition (FR). Previous CRC and SRC are originally designed in the real setting for grayscale image-based FR. They separately represent the color channels of a query color image […]
