“…The SPIHT compression of medical images is similar to conventional wavelet coding but it differs in encoding of the wavelet coefficients [4,8]. SPIHT coding exploits the wavelet transform hierarchical structure using treebased organization of the coefficients performs, partial ordering of the transformed coefficients by magnitude, and uses ordered bit plane transmission of refinement bits for the coefficient values.…”

Correlating objective and subjective quality assessment parameters of compressed digital medical images has been an open challenging problem in tele-radiology. Establishing this correlation is crucial in determining the upper limit of image compression threshold for preserving diagnostically relevant information based on mean opinion score (MOS). This paper presents a suitable method for finding correlation between PSNR and Structural Similarity (SSIM) index objective image quality parameters with subjective MOS for SPIHT [4] compressed medical images based on six independent observers. The suggested method can be potentially used for deciding upper compression thresholds for medical images. It is found that correlation coefficient (CC) between the PSNR and MOS for CT scan and MRI images are 0.979 and 0.960 respectively whereas their corresponding values are 0.868 and 0.955 considering SSIM. Further, MOS prediction models have been proposed considering PSNR and SSIM which closely match with the subjective MOS.

“…However more image is more accurately the amount of data generated is large [1]. Medical images such as functional MRI , dynamic and tomography image dynamic 3D echocardiography is increasingly used as they are considered among the most effective techniques in medical imaging, but they produce the most voluminous data , hence the need for their compression for storage and / or transport through networks of telecommunication [4].. Today, the large sizes use of numerical schemes in medical imaging (MRI, X scanner, nuclear medicine, etc.) generates massive volumes of data.…”

Abstract-The medical image processing process is one of the most important areas of research in medical applications in digitized medical information. A medical images have a large sizes. Since the coming of digital medical information, the important challenge is to care for the conduction and requirements of huge data, including medical images. Compression is considered as one of the necessary algorithm to explain this problem. A large amount of medical images must be compressed using lossless compression. This paper proposes a new medical image compression algorithm founded on lifting wavelet transform CDF 9/7 joined with SPIHT coding algorithm, this algorithm applied the lifting composition to confirm the benefit of the wavelet transform. To develop the proposed algorithm, the outcomes compared with other compression algorithm like JPEG codec. Experimental results proves that the anticipated algorithm is superior to another algorithm in both lossy and lossless compression for all medical images tested. The Wavelet-SPIHT algorithm provides PSNR very important values for MRI images.

“…Sonal and Kumar discussed the various aspects of Principle Component analysis (PCA) using statistical and neural network approaches for image compression [4]. Devi and Vidhya described a compression algorithm based on Cohen-Daubechies-Feauveau bi-orthogonal wavelet using set partitioning in hierarchical trees (SPIHT) method, which exhibited consistent image quality at lower bit rates, efficient compression ratio and good resolution in medical DICOM images [5].…”

Digital Imaging and Communications in Medicine (DICOM) is a standard image format for distribution and viewing of medical images from different modalities. For transmitting the medical images over the internet and for storing for future use, different compression techniques have been employed. This paper addressed most of the existing DICOM image compression techniques and studied the performance of the respective compression algorithms using visual inspection method and verified quantitatively in terms of compressed file size, compression ratio, PSNR and MSSIM.Finally, the optimum compression technique found from this study has been discussed in terms of the visual perception and performance metrics.
