3D human face recognition with 3D imaging technology is a frontier in image processing and pattern recognition. The 3D real-time human face imaging system based on CIS is able to obtain corresponding 2D gray data and 3D depth data from human face. Dimensionality reduction of high-dimensional observation data is the key problem of face recognition. This paper applies LOGMAP theory to dimensionality...
Experimental results show that Chlorella pyrenoidosa has an ability to accumulate and biodegrade phthalate esters. Bioconcentration factors of dimethyl phthalate (DMP), diethyl phthalate (DEP), and dibutyl phthalate (DBP) reached their maxima of 162 at 24 h, 205 at 12 h, and 4,077 at 12 h. The average biodegradation rates of DMP, DEP, and DBP per day were found to be 13.4 mg/L, 7.3 mg/L, and 2.1...
