“…IWT is the solution form, in which it is seen that using lifting scheme by the perfect reconstruction is possible. Also hardware Design of 2-D High Speed DWT by using Multiplier Wavelet Filters easier [16]. These methods for lossless medical image compression performing integer wavelet transform using lifting technique and then lossless predictive coding technique give efficient compression; different combinations of transformed and predicted images are inspected.…”

The future of healthcare delivery systems and telemedical applications will undergo a radical change due to the developments in wearable technologies, medical sensors, mobile computing, and communication techniques. When dealing with applications of collecting, sorting and transferring medical data from distant locations for performing remote medical collaborations and diagnosis we required to considered many parameters for telemedical application. E-health was born with the integration of networks and telecommunications. In recent years, healthcare systems rely on images acquired in two-dimensional domains in the case of still images or three-dimensional domains for volumetric video sequences and images. Images are acquired by many modalities including X-ray, magnetic resonance imaging, ultrasound, positron emission tomography, and computed axial tomography (Sapkal and Bairagi, 2011). Medical information is either in multidimensional or multiresolution form, which creates enormous amount of data. Retrieval, efficient storage, management, and transmission of these voluminous data are highly complex. One of the solutions to reduce this complex problem is to compress the medical data without any loss (i.e., lossless). Since the diagnostics capabilities are not compromised, this technique combines integer transforms and predictive coding to enhance the performance of lossless compression. The proposed techniques can be evaluated for performance using compression quality measures.

The wavelet transform has emerged as advanced technology in the field of VLSI implementation for image compression. Wavelet based coding provides improvements in picture quality at higher compression ratios. In this paper, we propose an efficient VLSI architecture for lifting based 5/3 DWT using FPGA. The lifting scheme 5/3 algorithm is used for implementing 1D-DWT architecture. The 2D-DWT lifting based architecture is designed using 1D-DWT lifting architectures. The proposed architecture uses less hardware interns of dedicated multipliers compared to existing architectures. The proposed architecture is implemented on Virtex-IV FPGA and it is observed that the parameters such as LUT's and delays are efficient.
