This paper presents an object recognition method; feature X-D such as Kanade- Lucas-Tomasi Feature (KLT)-D and Speeded-Up Robust Features (SURF)-D. The main idea of the proposed algorithm is to use distance method to achieve rotation and position invariance. The anchor point, a center point of the target boundary region, is proposed in this paper as the basis of the pose estimation and it can be obtained...
Special Sensor Microwave Imager/Sounder (SSMIS) on board the US Defense Meteorology Satellite Program (DMSP) satellites includes six upper atmosphere sounding (UAS) channels. Radiances in three of the UAS channels, channels 19 - 21, are influenced by a combination of Doppler shift caused by Earth's rotation and the effect of the Zeeman-splitting of the O2 magnetic transition. In order to operationally...
The logistic regression model has achieved success in spam filtering. But it is disadvantaged by the equal adjustment of the feature weights appeared in both spam messages and ham ones during training period. This paper presents an improved logistic regression model which reduces the impact of the features appearing in both spam messages and ham ones. Byte level n-grams are employed to extract the...
Extra-cellular signal regulated kinase (ERK) signal network plays an important role in regulating the fundamental cellular functions such as cell proliferation, survival, differentiation and motility. Development and analysis of mathematical model can help us acquire a deep understanding of the complex behavior of ERK signal transduction network. This paper presents a computational model that offers...
