Chapter
This paper covers new algorithms for digital signal processing of two-dimensional geophysical fields using octave method, which predicts the mineral value of the field in terms of signal energy value. In addition, it addresses and shows a functional scheme of the platform service based on cloud technologies. The essence of the work is that the geop...
Chapter
Electrogastrography (EGG) is a powerful instrument that represents and provides high time precision for direct heart activities. After processing the chest skin for the contact process by network electrodes, the conventional method of collecting heart signals involves the presence of electrodes directly connected to the patient’s chest using gelati...
Chapter
In this work, compression and zero coefficients have been determined by using digital processing of the blood image that is 1 μl (approximately one drop of blood) in the Haar wavelet. Also using this amount, an algorithm is proposed to define the number of leukocytes in human blood. We know that there are currently two types of methods for determin...

It is well-known that anyone who processes and analyzes image information needs a large amount of memory for storing images. For example, for storing a standard TV frame, if two of the three colors contain 2 bits for each of the 3 bits, the memory of at least 512×512 bytes is required. A passport image must be at least 64×64×64 bits (this requires...

Данная работа посвящена вопросам исследования и разработки модели и алгоритмов параллельной обработки одномерных (звуковых) и многомерных (изображений) сигналов на основе вейвлет-функций Хаара и Добеши. Разработка параллельных алгоритмов базируется на модели много поточной обработки данных с использованием библиотеки параллельного программирования...
Conference Paper
This paper is devoted to the research of bitmap image processing based on wavelet functions. The Daubechies wavelet function was used as a mathematical model for filtering, compression and smoothing of two-dimensional signals, because the analysis of existing wavelet functions showed that the Daubechies wavelet family is most effective for image pr...
