Abstract

Quaternion-based sparse strategies are an effective device for processing multimodal, multispectral images. These techniques employ the mathematical idea of quaternions, a four-dimensional extension of complex numbers, to accurately constitute and manage multidimensional facts. This permits the processing of multispectral images with high-dimensional records, along with hyperspectral images. One of the main advantages of the usage of quaternion-based sparse techniques is their ability to deal with actual and complex record. This makes them well-suitable for processing multimodal images ...
