Facial feature units’ localization using horizontal information of most significant bit planes

  We present here an approach to find the exact position of some feature units related to human face images. We use the horizontal information in most significant bit planes of images to accomplish the task. Finding location of facial feature units is of importance as most human face recognition approaches take it as initial point. The prominent feature units in a face are eyes, nostrils and lips which are...

N and P resorption efficiency and proficiency from leaves under different forest management systems of deciduous woody species

  Leaf N and P resorption efficiency and proficiency were explored in three permanent (non–tiled) and unfertilised plots: a Castanea sativa mill. paraclimax coppice (CC), a chestnut orchard (CO), and Quercus pyrenaica Wild. climax forest (Oak), adjacent to the CO plot, all located in central western Spain. To estimate the seasonal variation of the nutrients contained in the leaves, 9,...
