Preface

Fractal analysis is becoming more and more common in all walks of life. This includes biomedical engineering, steganography and art. Writing one book on all these topics is a very difficult task. For this reason, this book covers only selected topics. Interested readers will find in this book the topics of image compression, groundwater quality, establishing the downscaling and spatio-temporal scale conversion models of NDVI, modelling and optimization of 3T fractional nonlinear generalized magneto-thermoelastic multi-material, algebraic fractals in steganogra-

For example, one of the chapters covers the application of fractals to steganography. As is well known, steganography includes the technology of hiding watermarks in multimedia files. This technology is important in the field of copyright protection, secret communication and the form of information exchange. Contemporary image

analysis and processing methods allow the determination of the presence of embedded watermarks in a stegoimage on the basis of the original image and its statistical features. In this chapter, the authors propose the use of algebraic fractals for steganographic embedding of watermarks in colour images. The authors propose the use of algebraic fractals for an image serving as a secret key, which, according to the authors, allows for more resistant deposition to computer attacks,

In another chapter, the author describes the use of fractals to analyze the terrain surface using remote sensing. The author created the downscaling models using fractal theory for the parameters of the earth's surface in quantitative remote sensing. Additionally, it is still a hotspot for creating space-time conversion model parameters of the land surface in quantitative remote sensing in the future and marked in this connection, the author developed a multifractal scaling methodology

This book brings together a small collection of chapters covering specific aspects of the fractal field. I would like to thank the publishers (IntechOpen) for their help in preparing this book and the authors of the accepted manuscripts for their work and patience. For interested readers, I would like to suggest that they pay attention to

The book will definitely be of interest to scientists dealing with fractal analysis, as well as biomedical engineers or IT engineers. I encourage you to view individual chapters.
