AN EFFECTIVE THRESHOLD APPROACH FOR MEDICAL IMAGE COMPRESSION
Main Article Content
Abstract
The medical image compression methods aim to compress the image while ensuring that reduce the volume of storage in compression technique produce the good quality level images. The storage and transmission of medical images has made compression be required to digital world. In current research an efficient algorithm to compress and reconstruct the medical images. The newly proposed algorithm extracts edge information of medical images by using edge detector mechanism. Recent image compression techniques have increased the possibility by reducing the bandwidth requirement and cost-effective rescue of medical images for crucial analysis. The medical images are decomposed using Effective Discrete Wavelet Transform (EDWT). The wavelet coefficients are encoded using arithmetic coder. Better visual quality image is producing by newly proposed method at a lower bit rate compared with other standard compression algorithms. The image quality is evaluated by intention of image quality measures. The wavelet coefficients are encoded using Set Partitioning in Hierarchical Trees (SPIHT). The newly proposed algorithm is providing the enhancement function to improve the perceptual quality of the medical image. The newly proposed efficient compression algorithm to manage the increasing demands for image storage, quality and transmission time. Consistent Compression Ratio (CR), quality images are produced by this method compared with JPEG, SPIHT and MICT algorithm. Experimentation has been carried out on different image formats successfully. The proposed system achieved a good compression ratio and considerable test application for the quality of the reconstructed image.
