A New Technique in saving Fingerprint with low volume by using Chaos Game and Fractal Theory
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 12/2010)Fingerprint is one of the simplest and most reliable biometric features of human for identification. In this study by using fractal theory and by the assistance of Chaos Game a new fractal is made from fingerprint. While ... -
A Review on Block Matching Motion Estimation and Automata Theory based Approaches for Fractal Coding
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 12/2016)Fractal compression is the lossy compression technique in the field of gray/color image and video compression. It gives high compression ratio, better image quality with fast decoding time but improvement in encoding time ... -
Detection of Lung Nodules on Medical Images by the Use of Fractal Segmentation
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 09/2017)In the present paper, a method for the detection of malignant and benign tumors on the CT scan images has been proposed. In the proposed method, firstly the area of interest in which the tumor may exist is selected on the ... -
Modified Three-Step Search Block Matching Motion Estimation and Weighted Finite Automata based Fractal Video Compression
(International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI), 06/2017)The major challenge with fractal image/video coding technique is that, it requires more encoding time. Therefore, how to reduce the encoding time is the research component remains in the fractal coding. Block matching ... -
