With the development of science and technology, people have higher demand for comfortable seats. However, comfort is a complicated concept to apply in evaluating a sitting chair. There is no established assessment method which could evaluate the sitting chair comfort at present. Most of the current evaluation methods are based on single analysis, and lack multi-analysis of the problem. This paper...
Noninvasive measurement of blood pressure by optical methods receives considerable interest, but the complexity of the measurement and the difficulty of adjusting parameters restrict applications. We develop a method for estimating the systolic and diastolic blood pressure using a single-point optical recording of a photoplethysmographic (PPG) signal. The estimation is data-driven, we use automated...
Photoplethysmogram (PPG) signals acquired by smartphone cameras are weaker than those acquired by dedicated pulse oximeters. Furthermore, the signals have lower sampling rates, have notches in the waveform and are more severely affected by baseline drift, leading to specific morphological characteristics. This paper introduces a new feature, the inverted triangular area, to address these specific...
Optical Character Recognition (OCR) converts images of handwritten or printed text captured by camera or scanner into editable text. OCR has seen limited adoption in mobile platforms due to the performance constraints of these systems. Intel® Atom™ processors have enabled general purpose applications to be executed on handheld devices. In this paper, we analyze a reference implementation of the OCR...
An on-line BCI system is designed to control self-designed robot for photo-taking. The simulated experiment of BCI's application outside space-ship in aerospace is included in this paper. The P300-based BCI system includes three modules: visual stimulus, EEG sampling and signal processing, external robot controlling. A robot acts as the carrier for the camera. The robot is developed with the ability...
AVS-M is part seven of AVS standard, which is the second generation source coding standard of China. Because the system resource is limited in mobile platform compared with AVS P2, AVS-M has lower complexity, and is suitable for mobile-multimedia applications. The performance of AVS-M is close to H.264/AVC in the case of low rate bitstream. It is very important to increase the real-time encoding and...
