The polysomnographic and ventilatory patterns of nine normal adults were measured during non-rapid-eye-movement (NREM) stage 2 sleep before and after repeated administrations of a tone (40-72 dB) lasting 5 s. The ventilatory response to arousal (VRA) was determined in data sections showing electrocortical arousal following the start of the tone. Mean(More)
This paper presents a new framework for signboard recognition of signboards under adverse conditions. The framework is composed of two main stages newly proposed here: the main peak finding algorithm based on HSV color space to remove regions of occlusion and reflection, and the template matching to recognize objects. In the experiments, we used 300 images(More)
