چکیده
This paper describes Japanese phone recognition for lip reading based on a novel feature called trajectory feature to obtain high recognition rate. Trajectory feature is a time change of two mouth shape features expressed as a two-dimensional trajectory of the lip motion. The most similar trajectory in a database which is compared with the target trajectory by DP matching is selected as a result phone. Traditional researches concerned phone recognition experimented with only Japanese five vowels. In this paper, experiments were conducted for Japanese 45 phones with five person, and classified into five vowels and ten consonants, and recognition rate of 94.1% and 28.9%, respectively, were obtained.

Development of a rapid, one-step-visual method to detect Salmonella based on IC-LAMP method
Background: Salmonella can cause serious human gastroenteritis and is frequently isolated from various food samples. The cell culturing, immunoassay, and polymerase chain reactions (PCR) are the current methods to detect such pathogenic agents. However, these methods are time-consuming and labor-intensive, and thus unavailable for rapid-monitoring of Salmonella</em...
متن کاملSuperpixels Based Segmentation and SVM Based Classification Method to Distinguish Five Diseases from Normal Regions in Wireless Capsule Endoscopy
Wireless Capsule Endoscopy (WCE) is relatively a new technology to examine the entire GI trace. During an examination, it captures more than 55,000 frames. Reviewing all these images is time-consuming and prone to human error. It has been a challenge to develop intelligent methods assisting physicians to review the frames. The WCE frames are captured in 8-bit color depths which provides enough ...
متن کاملSaturation And Value Modulation (SVM): A New Method For Integrating Color And Grayscale Imagery
Algorithms for integrating color imagery with grayscale imagery have long been an important feature of many remote sensing (RS) image analysis and geographic information systems (G S). Traditional methods for data integration include Red-Green-Blue (RGB) /Hue-Saturation-Value (HSV) transformation and RGB modulation. However, these techniques are either inflexible or present a compromise between...
متن کاملInvestigating the Role of Code Smells in Preventive Maintenance
The quest for improving the software quality has given rise to various studies which focus on the enhancement of the quality of software through various processes. Code smells, which are indicators of the software quality have not been put to an extensive study for as to determine their role in the prediction of defects in the software. This study aims to investigate the role of code smells in ...
متن کاملAn Automatic Face Detection and Gender Classification from Color Images using Support Vector Machine
This paper presents combined face detection and gender classification method of discriminating between faces of men and women. This is done by detecting the human face area in image given and detecting facial features based on the measurements in pixels. The proposed algorithm converts the RGB image into the YCbCr color space to detect the skin regions from the facial image. But in order to det...
