 The Image Analysis Group is concerned with advanced analysis of biological imagery. The main thrust of research is to develop novel techniques for automatically extracting high-level information from the full range of images generated by the biologists. Current research is focused on two main areas of biological research: the effects of retinal detachment and microtubule dynamics. The retina group is working on algorithms for automated cell counting, layer segmentation, texture analysis, and a host of other quantifiers. The microtubule group is working on techniques for tracking microtubules as well as analyzing microtubule dynamics.

Project Objective
With the emergence of smart phones and their increasing popularity, we envision
a mobile application capable of plant identifi cation from geo-tagged images. The
application sends user generated images to the server, and retrieves information
about plant taxonomy and habitat. The system uses plant features such as leaf
properties, branching structure, and flower attributes, where applicable, as well
as location information, to identify the species. The server returns a list of plant
species that are closely related based on phenotypical characteristics.
Plant Identification System
Coal Oil Point Reserve
Devereux Slough - Januuary, 24, 2008
The University of California (UC) Natural Reserve System (NRS) manages 37
natural areas representing nearly all the State's major ecosystems in as undisturbed a condition as possible. This reserve system protects California's natural
heritage for the public trust and provides protected natural areas for research
and teaching to contribute to the understanding and wise management of the Earth and its natural systems. The Coal Oil Point Reserve is one of these re-
serves and o ers many opportunities for public and student education as well
as research.
The Coal Oil Point Natural Reserve (COPR) consists of 170 acres of protected coastal habitats along the south coast of Santa Barbara County, adjacent
to the West Campus of the UCSB. The diversity of habitats and wildlife at the
Reserve is striking and some of these species are now rare along the coast. For
example, the COPR beach is breeding habitat for the Pacifi c coastal population
of the threatened Western Snowy Plover and the endangered California Least
Terns. The Belding savanna Sparrow breeds on the pickleweed habitat at Devereux slough. The Reserve has one of the most pristine remnants of Coastal
Dune Scrub in Santa Barbara County, and contains a number of rare plant
species. Several types of wetlands such as vernal pool, dune swale, salt
at and
salt marsh are part of the 5% remaining coastal wetland in California. In a
short walk, visitors can observe all these habitats and learn why it is important
to preserve them.
Easy access to the Reserve's great natural beauty provides an opportunity to
foster education and connect people to nature. One way to help to engage people
with their local environment is by teaching them to recognize the native plant
species. This project will provide a cutting edge tool to help people identify
plants. The reserve's 3 mile nature trail contains a number of plants from the
coastal scrub community, the most important vegetation, and the one with the
fastest decline in coastal California. People love what they know and protect
what they love. Thus, by learning the local
ora, people will help preserve it.
Plant Itendification Challenges
The difficulty in plant identification comes from the fact that all elements of the plant (flower, leaf, branching structure, etc) give clues that need to be examined in order to identify the plant. Therefore, our system cannot be limited to leaves, like other plant identification systems already existent. Furthermore, the variety of types of leaves and flowers as well as complicated 3-d geometry of the branching structure of leaves and petals poses difficulty. Our system aims at addresses these challenges and taking advantage of as many plant features as possible, 2-d as well as 3-d.
Variety in imaging subjects: whole plant, leaf, branch, flower
Data Collection Process
During the summer of 2010 we started a systematic data collection process (one
undergraduate research intern and a graduate student mentor have been involved in this work, supervised by Professor Manjunath and the Director of the COPR).
We are collecting data along the trail mentioned in above. Also, the appearance of plants varies greatly throughout the year, so our e fort of data collection
will be ongoing work.
Throughout the data collection process, we consider the variety in features
from plant to plant as well as leaf to leaf on the same plant, but we assume
that the query images only contain mature healthy leaves, and healthy fully
blossomed
flowers. Also, we do not constrain the user image the plant on a
white background, but we do expect a uniform background. We do not
consider trees at this point.
As mentioned above, we aim at extracting 2D features, such as leaf geometry,
venation structure, as well as 3D features, such as shape of the leaf and branching
structure. Ideally, the user should be able to take several pictures from diff erent
angles in order to be able to extract the 3D structure. We also consider the
possibility of providing the user with a wallet-sized calibration pattern which
should be captured in the query images.
We collect data in the following manner. The camera is calibrated using a checkerboard pattern.
Images from multiple angles are required for the computation of 3D features. The
procedure for multi-pose imaging is illustrated in the figure below The checkerboard
pattern and the color calibration patterns are mounted next to the target. Several images from diff erent angles are taken. The calibration information allows
us to estimate the relative position of the two cameras in the two poses. The
target can be one of the subjects discussed above: leaf,
flower, fruit, branch and whole plant.

Building the Database
Images are collected as explained above. The imaged subject can be:
leaf,
flower, branch, fruit, whole plant, or a combination thereof. The subject can be
photographed with one view, or with multiple views, depending on whether 2D or
3D features will be extracted. Every image comes with date/time information
and GPS coordinates. The data is stored in the BISQUE system which the VRL maintains.
The figure below explains the information that is annotated for every image collected.
This information includes, but is not restricted to: genus and species, ecology
information (such as habitat, seasonal variations, etc), phenotypical features
(age and physical characteristics). Additionally, several maps are available from
COPR (geology, habitat, topography and hydrology maps). The information
in these maps is extracted using the GPS coordinates and is associated with
the plant. Thus, for example, plants belonging to a specific habitat will be
marked according to the maps. Also, to aid the image segmentation process,
the background type can be specifi ed as natural or artifi cial (such as a white
paper). Features that are later extracted using image processing techniques, are
also associated with the image, and can later be retrieved for classifi cation.

User Query System
The figure below shows the system that we envision once the database is complete. The
user takes a picture of a portion of the plant with their smart phone. The
image is sent to the server, along with information about date, time and GPS
coordinates. Additionally the system asks the user to clarify what portion of the
plant is visible (leaf, branch, etc). Optional parameters can also be specifi ed to
aid the feature extraction and classifi cation. Such optional parameters include
the age of the plant, phenotypical information, the type of background present
in the image (natural or arti ficial), as well as certain keywords which can narrow
down the classi fication.
Once the information is received on the server, plant features can be extracted and matched with the database. The GPS coordinates are used to
pull up information from the geology, habitat, topography and hydrology maps.
The time and date are used to extract season information. Speci fic features are
extracted using image processing techniques, as described in the figure below. These
features are used for classi fication, and the closest plant species, if any, are
returned to the user, along with some relevant information.
User Query System
Infrastructure
We are in the process of building the database of geo-tagged images, along the 3
mile nature trail at the Coal Oil Point Reserve. These images include pictures of
leaves, branches, flowers, fruit and whole plants. The reservation includes roughly 130
native species, of which about 30 are common. We currently aim at obtaining
images of the common species along the trail over all seasons. The images are
obtained using a DSLR camera (Canon EOS 7D) together with a GPS device (i-
gatU GT-120). The database is incorporated into the Bio-Image Semantic
Query User Environment (BISQUE) system that the VRL maintains.
The Bisque is a web-based platform speci fically designed to provide researchers
with organizational and quantitative analysis tools for 5D image data. Users
can extend Bisque with both data model and analysis extensions in order to
adapt the system to local needs. Bisque's extensibility stems from two core concepts:
flexible metadata facility and an open web-based architecture. Together
these empower researchers to create, develop and share novel bioimage analysis. Bisque is web based, cross-platform and open-source. The system is also
available as software-as-a-service through the Center of Bioimage Informatics at
UCSB.
