The key points of improving the efficiency of base point choice algorithm of ECC on GF (p) are judging quadratic residue, getting Y-coordinate and scalar multiplication. A new algorithm of judging quadratic residue and getting Y-coordinate is proposed and analyzed in the paper by defining a min class of quadratic residue, and some methods for improving the efficiency of scalar multiplication are discussed...
This paper presents improved mountain clustering technique based MRI (magnetic resonance imaging) brain image segmentation for spotting tumors. The proposed technique is compared with some existing techniques such as K-Means and FCM, clustering. The performance of all these clustering techniques is compared in terms of cluster entropy as a measure of information and also is visually compared for image...
This paper presents Improved Mountain Clustering (IMC) based medical image segmentation. Proposed technique is a more powerful approach for X-Ray image based diagnosing diseases like lung cancer and tuberculosis. The IMC based segmentation approach was applied on lung X-Ray images and compared with some existing techniques such as K-Means and FCM based segmentation approaches. The performance of all...
