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

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
