Research ArticleOpen accessIncorporation of Modified Region Growing into FCM Clustering for Extraction of Tumors in MR ImagesLovepreet Singh Brar, Jaget Singh, Bhawana Agrawal et al.Due to the tremendous growth of medical Magnetic Resonance (MR) images, it becomes an essential requirement for an automated extraction of diagnostically salient parts of the images to refine the transmission and storage process. Research method: This paper proposes an automated unsupervised machine learning segmentation technique named fuzzy c-means clustering based on modified region growing algorithm (RG-FCM) for the extraction … …Journal of Computer Science, Vol. 21, Issue 12 · 12 Feb 2026 · 1,477 accessesView PDF Cite

Research ArticleOpen accessConcealed Weapon Detection using Wavelet, Dual Tree Complex Wavelet Transform and Curvelet TransformAyush Dogra, Bhawna Goyal, Sunil Agrawal et al.In the field of military and law enforcement, detection and visualization of concealed weapons is a common practice. The infrared and visible cameras providing the information i.e., the characteristic visual features of the image and the thermal radiations are able to provide the complementary information like information about concealed objects or weapons. In this manuscript, we have proposed the integration … …Journal of Computer Science, Vol. 14, Issue 10 · 26 Oct 2018 · 7,252 accessesView PDF Cite
