Four new inter-nucleotide distance sequences for a DNA sequence are defined. They are different from ones presented by Afreixo et al., and overcome the irreversible defect of the global inter-nucleotide distance sequence proposed by Nair and Mahalakshmi. Five basic statistical quantities are extracted from (ordered) precise inter-nucleotide distance sequences to construct a 20 dimensional feature...
Facial expressions are considered a critical factor in neonatal pain assessment. This paper attempts to apply modern facial expression recognition techniques to the task of distinguishing pain expression from non-pain expression. Firstly, 2D Gabor filter is applied to extract the expression features from facial images. Then we apply Adaboost as a feature selection tool to remove the redundant Gabor...
