Medical image diagnosis acts an important role recently to protect the life and cure illnesses and therefore practice of medical images is radically improved. Developing technological developments to meet up the memory needs of everyday life looks not to satisfy the necessity of storage as data storage is proportionally improving. Image compression is the crucial solution to satisfy the storage necessities. The prior work presented a numerous compression methods dependent upon Region of Interest (ROI). In this work, an efficient retinal image compression method based on modified Huffman method is presented. The proposed method is designed for improving the storage efficiency and high security. First, the Pre-processing is performed by using Adaptive median filter. To separate out ROI from the preprocessed image, segmentation is performed using Improved Adaptive Fuzzy C-means Clustering. The separated ROI/non-ROI regions are compressed by using Integer Multi Wavelet Transform and Set Partitioning in Hierarchical Trees algorithms respectively. Further, threshold improved zero tree wavelet algorithm is applied on the whole image, and then modified Huffman encoding is performed to obtain compressed image for transmission. The proposed method is tested using a Local database which is collected from local hospitals. The proposed method is a suitable medical image compression with the expected image quality based on the experiments. It’s found that the proposed method yields slightly better CR, PSNR and MSE values compared to existing methods.
