Abstract
Signal processing of brain activity poses challenges to various researchers from different areas, including medical, biomedical, and engineering researchers. Taking the benefits from rapidly developing higher technologies, the outcomes of the research into brain activity have made great progresses. In this paper, investigations of brain activity are made from experimental works, with optical flow based on spatiotemporal analysis and wavelet with near infrared spectroscopy (NIRS). Ant colony optimization (ACO) algorithm is employed for obtaining the distributions of the intensity of the targeted image. The major outcomes of our research are the following five items: (1) optical flow is a proper technology for the investigation of brain activity based on NIRS; (2) the results of the temporal domain, spatial domain, and wavelet domain support each other through experimental results; (3) our wavelet analysis offers the most brain activity, defined as targeted image; (4) the details of the intensity distribution on the targeted image show the most significant brain activity via ACO; (5) we can clearly observe, via our algorithm technology, the existence of the so-called dominant channel (DC) based on spatiotemporal analysis and it plays a critical role in brain activity. The spatial distribution of the origin of cortical activity can be described by hemodynamic response in the cerebral cortex after evoked stimulation using near infrared spectroscopy. Further application of this research is expected in the next step research outcomes

| Other | The International Conference on Communications and Electronics (ICCE) has become a prestige bi-annual international conference series in the area of Electronics and Communications recently. This time, the sixth ICCE (IEEE ICCE 2016) will be organized as a celebration on the occasion of the 60th anniversary of the Hanoi University of Science and Technology. In addition, IEEE ICCE 2016 will also be an event to mark its 10th anniversary. Following the past successful IEEE ICCE 2014, which received 228 submissions from 30 countries with the acceptance rate of 42%, the sixth ICCE (IEEE ICCE 2016) looks for significant contribution to various topics in communications engineering, networking, microwave engineering, signal processing and electronic engineering. The conference will also include tutorials, workshops, and technology panels given by world-class speakers. Besides the scientific activities, as IEEE ICCE 2016 will be held in the spectacular World-Heritage Site – Halong Bay, here, your passion of nature discovery will be awakened |
