This dissertation addresses two fundamental problems in computer vision—namely,
multitarget tracking and event recognition in videos. These problems are challenging
because uncertainty may arise from a host of sources, including motion blur,
occlusions, and dynamic cluttered backgrounds. We show that these challenges can be
successfully addressed by using a multiscale,...
Artists use different means of stylization to control the
focus on different objects in the scene. This allows them to portray complex meaning and achieve certain artistic effects. Most
prior work on painterly rendering of videos, however, uses only
a single painting style, with fixed global parameters, irrespective of objects...
Indole-3-carbinol (I3C) is a naturally occurring plant alkaloid, found in significant concentrations in cruciferous vegetables such as broccoli and Brussels sprouts. I3C is an unstable compound that undergoes rapid oligomerization in an acidic environment to form higher order condensation products (I3C-ACPs), such as 3-3'-diindolylmethane (DIM). Both I3C and DIM are...
There is plenty of evidence from epidemiology studies
supporting a link between certain components in the human
diet and cancer incidence. It is estimated that 3-4 million
annual cases of cancer could be prevented worldwide just by
changing dietary habits. In parts of the world where
vegetables and fruits constitute...
Symbioses between microbes and multicellular eukaryotes are found in all biomes, and encompass a spectrum of symbiotic lifestyles that includes parasitism and disease, commensalism, and mutually beneficial interdependent host-microbe relationships. Regardless of outcome, these symbiotic lifestyles are governed by a complex molecular "courtship" between microbe and potential host. This courtship...
Rice, maize, sorghum, wheat, barley and the other
major crop grasses from the family Poaceae
(Gramineae) are mankind’s most important source
of calories and contribute tens of billions of dollars
annually to the world economy (FAO 1999, http://www.fao.org; USDA 1997, http://www.usda.gov).
Continued improvement of Poaceae crops is necessary
in order...
Gramene (www.gramene.org) is a curated resource
for genetic, genomic and comparative genomics
data for the major crop species, including rice,
maize, wheat and many other plant (mainly grass)
species. Gramene is an open-source project.
All data and software are freely downloadable
through the ftp site (ftp.gramene.org/pub/gramene)
and available for use...
3D object recognition is a very difficult and important problem in computer vision, arising in a wide range of applications. Typically in 3D object recognition, interest points are extracted from images and then matched. A shortcoming of this approach is that points only carry local visual information. Therefore, there
could...
BACKGROUND:
Plant gametophytes play central roles in sexual reproduction. A hallmark of the plant life
cycle is that gene expression is required in the haploid gametophytes. Consequently, many
mutant phenotypes are expressed in this phase.
RESULTS:
We perform a quantitative RNA-seq analysis of embryo sacs, comparator ovules with the
embryo...
