ProjectsWhitecap Analysis
Image processing April – May 2013 Calculate percent of
whitecap coverage vs. time
Seabubbles Analysis Video analysis January – February 2000 Calculate maximum
depth of bubble plumes vs. time
Whitecap AnalysisStep 1: Process the images
Whitecap AnalysisStep 2: Analyze images and create time series
Whitecap AnalysisStep 3: Extract events
Whitecap AnalysisStep 4: Calculate parameters and save data
noise

Event 1
Event 1
Seabubbles AnalysisStep 1: Convert videos to readable files
DV Movie Files
AVI Movi
e Files
JPEG Images
Seabubbles AnalysisStep 2: Calculate max depth of bubble plume
over time
x
d
depth = .1459 m
Seabubbles AnalysisCommon problems:
Sun’s reflection Placement of event
Event not visible in both above water and under water cam
Bad angle
depth = .2391 m
x
dSun’s reflection
ConclusionWhat I Did
Processed images into readable time series extracted events and
calculated parameters for whitecap coverage
Processed videos and calculated bubble plume depth over time
What I Learned Better programmer Comment and document
code
