This reference book collates traditional and modern applications of remote sensing in aquatic ecosystem monitoring. It covers conventional assessment methods like sampling, surveying, and chlorophyll estimation. Advanced remote sensing technology provides timely spectral information for quantitative and qualitative assessment of water changes, volume, and vegetation. The book discusses space-borne, airborne, and drone geospatial data. The five sections broadly cover aquatic ecosystem monitoring, vegetation management, advanced modelling practices, and challenges. Key featuresCovers different types of aquatic ecosystems like wetlands, rivers, lakes, saline, and brackishReviews the latest applications of remote sensing in the monitoring and assessment of aquatic ecosystemsIncludes traditional methods like cartography, sampling, surveying, phytoplankton assessment and chlorophyll estimationDiscusses the application of artificial intelligence, machine learning, data fusion in monitoring aquatic systemsExplores the prospects of future Earth observation space missions for aquatic ecosystem monitoringThe book is meant for scientists, professionals, and policymakers working in environmental sciences, remote sensing, and geology.

Opening with a detailed review of existing techniques for selective encryption, this text then examines algorithms that combine both encryption and compression. The book also presents a selection of specific examples of the design and implementation of secure embedded multimedia systems. Features: reviews the historical developments and latest techniques in multimedia compression and encryption; discusses an approach to reduce the computational cost of multimedia encryption, while preserving the properties of compressed video; introduces a polymorphic wavelet architecture that can make dynamic resource allocation decisions according to the application requirements; proposes a light-weight multimedia encryption strategy based on a modified discrete wavelet transform; describes a reconfigurable hardware implementation of a chaotic filter bank scheme with enhanced security features; presents an encryption scheme for image and video data based on chaotic arithmetic coding.
