It is always a better option to compress the diagnostic important region in a lossless manner and the remaining portion of the image with a near-lossless compression method to achieve high compression efficiency without any compromise of quality. The predictive ROI-based compression on volumetric CT medical image is proposed in this paper; resolution-independent gradient edge detection (RIGED) and block adaptive arithmetic encoding (BAAE) are employed to ROI part for prediction and encoding that reduce the interpixel and coding redundancy. For the non-ROI portion, RIGED with an optimal threshold value, quantizer with optimal [Formula: see text]-level and BAAE with optimal block size are utilized for compression. The volumetric 8-bit and 16-bit standard CT image dataset is utilized for the evaluation of the proposed technique, and results are validated on real-time CT images collected from the hospital. Performance of the proposed technique in terms of BPP outperforms existing techniques such as JPEG 2000, M-CALIC, JPEG-LS, CALIC and JP3D by 20.31%, 19.87%, 17.77%, 15.58% and 13.66%, respectively. <\/jats:p>","DOI":"10.1142\/s0219467821500212","type":"journal-article","created":{"date-parts":[[2020,10,31]],"date-time":"2020-10-31T07:36:47Z","timestamp":1604129807000},"page":"2150021","source":"Crossref","is-referenced-by-count":0,"title":["Region of Interest-Based Coding Technique of Medical Images Using Varying Grading of Compression"],"prefix":"10.1142","volume":"21","author":[{"given":"Urvashi","family":"Sharma","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication Engineering, Jaypee University of Information Technology, Waknaghat, Himachal Pradesh, India"}]},{"given":"Meenakshi","family":"Sood","sequence":"additional","affiliation":[{"name":"National Institute of Technical Teachers Training and Research, Chandigarh, India"}]},{"given":"Emjee","family":"Puthooran","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Jaypee University of Information Technology, Waknaghat, Himachal Pradesh, India"}]}],"member":"219","published-online":{"date-parts":[[2020,12,19]]},"reference":[{"key":"S0219467821500212BIB001","doi-asserted-by":"publisher","DOI":"10.1118\/1.2218316"},{"key":"S0219467821500212BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/42.310885"},{"key":"S0219467821500212BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/IACC.2016.81"},{"key":"S0219467821500212BIB004","doi-asserted-by":"publisher","DOI":"10.1134\/S1054661812010191"},{"key":"S0219467821500212BIB005","doi-asserted-by":"publisher","DOI":"10.1109\/26.585919"},{"key":"S0219467821500212BIB006","first-page":"131","volume-title":"Proc.
