| Summary: | In modern information and measuring systems (IMS), the most informative type of data is images. These can be images that characterize the condition of patients, and the system will have medical applications. Images can be formed in the visible range of electromagnetic radiation waves, or can be the result of recording other types of radiation. High information content, as an important advantage of images, leads to the need to transmit and store a large amount of digital data. Therefore, for effective use of computerized IMS resources, it is necessary to reduce this volume by compression. The required number of compression times is from several tens to hundreds of times.
The article considers the theoretical foundations of the direct and inverse wavelet transform and its application in image compression procedures for medical applications, which occurs with some loss of information. By controlling the compression procedure and choosing its parameters, it is possible to ensure an acceptable error in image recovery.
It is determined that compression based on the selected wavelet type is possible when it is orthogonal and, accordingly, there is an inverse wavelet transform. Also, to increase the speed of compression procedures, it is proposed to divide the wavelet transform into two one-dimensional procedures applied to rows and columns of the image.
An example of the influence of wavelet compression in the JPEG-2000 format on the accuracy of transmitting information about geometric parameters and coordinates of contour points of objects in medical applications of images in IBS is considered. |
