Data compression is one of the main contributing factors in the explosive growth in information technology. Without it, a number of consumer and commercial products, such as DVD, videophone, digital camera, MP3, video-streaming and wireless PCS, would have been virtually impossible. Transforming the data to a frequency or other domain enables even more efficient compression. By illustrating this intimate link, The Transform and Data Compression Handbook serves as a much-needed handbook for a wide range of researchers and engineers. The authors describe various discrete transforms and their applications in different disciplines. They cover techniques, such as adaptive quantization and entropy coding, that result in significant reduction in bit rates when applied to the transform coefficients. With clear and concise presentations of the ideas and concepts, as well as detailed descriptions of the algorithms, the authors provide important insight into the applications and their limitations. Data compression is an essential step towards the efficient storage and transmission of information. The Transform and Data Compression Handbook provides a wealth of information regarding different discrete transforms and demonstrates their power and practicality in data compression.

This is the first comprehensive treatment of the theoretical aspects of the discrete cosine transform (DCT), which is being recommended by various standards organizations, such as the CCITT, ISO etc., as the primary compression tool in digital image coding. The main purpose of the book is to provide a complete source for the user of this signal processing tool, where both the basics and the applications are detailed. An extensive bibliography covers both the theory and applications of the DCT. The novice will find the book useful in its self-contained treatment of the theory of the DCT, the detailed description of various algorithms supported by computer programs and the range of possible applications, including codecs used for teleconferencing, videophone, progressive image transmission, and broadcast TV. The more advanced user will appreciate the extensive references. Tables describing ASIC VLSI chips for implementing DCT, and motion estimation and details on image compression boards are also provided.

Huge amount of data recorded during exercise electrocardiography may be stored for further analysis or be transferred to a remote physician through telephone lines, Due to channel limitations, data must be compressed prior to the transfer, In this study, an algorithm suitable for compression of exercise electrocardiography data is proposed, 2-D Discrete Cosine Transformation is applied in the algorithm to make use of the pseudo periodic behavior of the data, To increase the correlation, data is aligned from the R peaks, QRS detection is performed using Fast Dyadic Wavelet Transform, The success rate of the detection algorithm is found to be 99,78%, Uniform scalar quantization is used with zonal coding method in the coding of 2-D Discrete Cosine Transform coefficients, The performance of the compression algorithm is evaluated in terms of compression ratio, reconstruction error and by compaflw the reports of the ST segment depression test applied before the compression and after the reconstruction to inspect whether vital information is preserved,

The concept of this book is ECG signals- Electrocardiography is connected with Arduino UNO- microcontroller. This book demonstrates how our heart waves can be connected to a microcontroller. What kind of obstruction or change occurs in the wave according to the different changes of the atmosphere can be known from this book. The ECG Signal plays an important role in the diagnosis of heart diseases and disorders. An ECG is a significant physiological signal for diagnosis of cardiac disease. Modern usage of monitoring devices with electrocardiogram is increasing. Huge storage space and large quantities of data are that, and ECG compression is required for efficient storage and it has been extracted from a medical database. Aninteresting research line focuses on transforming the original one-dimensional waveforms of the ECG into two-dimensional information, followed by a processing stage using image processing tools. Many cardiac abnormalities can be observed with the aid of an ECG interpretation including inadequate blood flow, heart muscle death due to coronary thrombosis and heart muscle enlargement. Arduino can be used to for the development of interactive objects, taking inputs to control outputs. It is connected to the Arduino hardware to communicate and upload sketches. Arduino can read information from input devices such as Trimmer(potentiometer), Antenna, Sensors, e.t.c, and can also send data to the output devices such as Speakers, LED, DC motor, LCD Screen, e.t.c. User communities are groups of people using a given product, the Arduino in this case. So, the design has been enhanced, and it helps drive the Arduino board for direction to future.
