Webin SOZ localization on a real EEG dataset collected from epilepsy patients who underwent epilepsy surgery. Our results indicate that utilizing the spatial and temporal dependencies in addition to observations made in the EEG provides a 5–7% improvement in the AUC (0.72, 0.67, 0.65) and outperforms alternative approaches utilized for SOZ ... WebAn important feature of human vision is the poor spatial resolution for certain types of colors. The largest effect arises in the short-wavelength region of the spectrum. In this region, chromatic aberration of the human cornea and lens limits spatial resolution to 6 cycles per degree (cpd) (see Chapter 2; Wandell, 1995: ch. 2). modern high end pool table
