Monotonic Tree of Images and Its Application in Image Processing
Contour trees have been used in geographic information systems (GIS) and medical imaging to display scalar data. Contours are only defined for continuous functions. For an image represented by discrete data, a continuous function is first defined as an interpolation of the data. Then the contour tree is defined on this continuous function. In this paper, we introduce a new concept termed monoto...

متن کاملLocating Image Background By Monotonic Tree
In this paper, we discuss an approach to locating image background, which is based on monotonic tree, a derivation of contour tree for discrete data. We first make two assumptions about image background. As compared with the foreground shapes, the background regions are (1) smoother in intensity; and (2) peripheral in location. In an input image, the harshness of the foreground is characterized...
متن کاملMultiple Region Categorization for Scenery Images
We present two novel contributions to the problem of region classification in scenery/landscape images. The first is a model that incorporates local cues with global layout cues, following the statistical characteristics recently suggested in [1]. The observation that background regions in scenery images tend to horizontally span the image allows us to represent the contextual dependencies betw...
متن کاملAnalyzing the Family Tree
FamilySearch holds one of the largest collections of linked family history data in the world. Nearly one billion records of individuals, both deceased and living, have been recorded and placed together into a common tree (“The Family Tree”). The study of this ancestral relationship graph consists of the largest family history network ever analyzed. We have found a number of interesting properti...
