—Aiming at pose-invariant face recognition, this paper proposes a method of generating virtual frontal view from a non-frontal face image. we use the virtual frontal face image instead of the input non-frontal image as the test image with the exertion of Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) to finally achieve face(More)
Apoptosis, or programmed cell death, plays an important role in development of an organism. Obtaining information on subcellular location of apoptosis proteins is very helpful to understand the apoptosis mechanism. In this paper, based on the hydropathy characteristics, a novel feature extraction method with triplet composition features for reduced protein(More)
Apoptosis, or programed cell death, plays a central role in the development and homeostasis of an organism. Obtaining information on subcellular location of apoptosis proteins is very helpful for understanding the apoptosis mechanism. The prediction of subcellular localization of an apoptosis protein is still a challenging task, and existing methods mainly(More)
Prediction of protein structural classes for low-similarity sequences is useful for understanding fold patterns, regulation, functions, and interactions of proteins. It is well known that feature extraction is significant to prediction of protein structural class and it mainly uses protein primary sequence, predicted secondary structure sequence, and(More)
