We propose a method for leveraging publicly available labeled facial age datasets to estimate age from unconstrained face images at the ChaLearn Looking at People (LAP) challenge 2015 [9]. We first learn discriminative age related representation on multiple publicly available age datasets using deep Convolutional Neural Networks (CNN). Training CNN is supervised by rich binary codes, and thus modeled...
In this work the modeling and calibration method of reciprocity error in a coherent TDD coordinated multi-point (CoMP) joint transmission (JT) system are addressed. The modeling includes parameters such as amplitude gains and phase differences of RF chains between the eNBs. The calibration method used for inter-cell antenna calibration is based on precoding matrix indicator (PMI) feedback by UE. Furthermore,...
Head pose estimation remains a unique challenge for computer vision system due to identity variation, illumination changes, noise, etc. Previous statistical approaches like PCA, linear discriminative analysis (LDA) and machine learning methods, including SVM and Adaboost, cannot achieve both accuracy and robustness that well. In this paper, we propose to use Gabor feature based random forests as the...
This paper reports the advancement of a research extension. The outcome is a device installed in a long-haul bus for daily operation. The incumbent system features the combination of lane departure warning (LDW) function and forward collision warning (FCW) function employing the support vector machine (SVM) as the classifier. LDW recognizes the environment as in daytime or in nighttime by detecting...
