Proceedings ArticleDOI
Real-time multiple face detection and tracking
TL;DR: One of the main advantages of the proposed method is its robustness against usual challenges in face tracking such as scaling, rotation, scene changes, fast movements, and partial occlusions.
Journal ArticleDOI

Samireh Badrigilan,Shahabedin Nabavi,Ahmad Ali Abin,Nima Rostampour,Iraj Abedi,Atefeh Shirvani,Mohsen Ebrahimi Moghaddam +6 more
TL;DR: In this paper, the authors used statistical methods to analyze studies related to segmentation and classification of head and neck cancers (HNCs) and brain tumors in MRI images, which achieved the highest performance for classifying three types of glioma, meningioma and pituitary tumors with overall accuracies of 96.01, 99.73, and 96.58%, respectively.
Journal ArticleDOI
A Random Walk Approach to Query Informative Constraints for Clustering
TL;DR: A random walk approach to the problem of querying informative constraints for clustering, based on the properties of the commute time, that is the expected time taken for a random walk to travel between two nodes and return, on the adjacency graph of data.
Journal ArticleDOI
A Density-based Approach for Querying Informative Constraints for Clustering
Ahmad Ali Abin,Viet-Vu Vu +1 more
TL;DR: A new method is proposed that estimates density and impurity of data points on different adjacency distances and calculates centrality for each data point by applying a density tracking approach on the obtained densities and selection of constraints from skeleton of clusters in order to discover the intrinsic structure of data.
Proceedings ArticleDOI
Cellular learning automata-based color image segmentation using adaptive chains
TL;DR: Experimental results show the effectiveness of the proposed segmentation method, which is based on CLA and can adapt to its environment after some iterations and leads to a semi content-based segmentation process that performs well even in presence of noise.
