Comparison of Several Visual Stimuli for Development of a Brain Computer Interface Based on Steady-State Visual Evoked Potentials

Mohsen Keshtkar; Amin Mahnam; Pegah Poladian

Volume 10, Issue 4 , January 2017, Pages 279-290

  Steady State Visual Evoked Potentials (SSVEP) have been widely used in development of Brain Computer Interfaces (BCI). However, it is still a research challenge to have visual stimuli which provide strong SSVEP response while produce little eye fatigue. In this study, rectangular, sinosoidal, sawtooth ...  Read More

A New Method for Segmentation of Skin Lesions in Dermoscopy Images: Energy Optimization Based on the Radial Directions

Marjan Iranianpour Haghighi; Seyyed Vahab Shojaeddini

Volume 10, Issue 4 , January 2017, Pages 291-302

  Detecting lesion borders is the first step for intelligent lesion identification in dermoscopy, therefore it may influence the accuracy and validity of the next steps of this process. Unfortunately, extracting borders is hampered by some challenges such as losses associated with irregular borders, poor ...  Read More

Global Wall Motion Estimation of Echocardiographic Images Based on Temporal Information and Sparse Representations

Parisa Gifani; Hamid Behnam; Maryam Shojaee Fard

Volume 10, Issue 4 , January 2017, Pages 303-313

  In this paper, we introduce a novel framework for illustrating the cardiac movements in echocardiogarphic images by utilizing temporal information and sparse representation. For the proposed method, we first derived temporal information by extracting intensity variation time curves (IVTC) assessed for ...  Read More

Evaluation of Bone Butterfly Fracture by Controlling the Applied Load at Different Strain Rates

Mahmoud Reza Azghani; Sharareh Kian-Bostanabad; Tara Ahmadi; Hamid Khabiri

Volume 10, Issue 4 , January 2017, Pages 339-346

  Long bone fracture is the most prevalent traumatic fractures that accures due to the strike and attacted load exertions, which one of them is the butterfly fracture. This type of fracture may happen with sudden and combined forces. Since in this type of fracture, the number of fracture lines is more ...  Read More

Enhanced Fast Fully Adaptive Beamformer for Localizing Brain Short Time Activities

Alireza Talesh Jafadideh; Babak Mohammadzadeh Asl

Volume 10, Issue 4 , January 2017, Pages 347-359

  Minimum variance beamformer (MVB) and its extensions are most widely used techniques in brain source localization due to their high spatial resolution.  Unfortunately, beacause of using data covariance matrix, these methods often fail when the number of samples of the recorded data sequences is ...  Read More
