Canny Edge DetectorGaussian filter to smooth image
1st derivative kernel to detect edges
Non-maximal suppression
Median filter
• B = medfilt2(im) does a median filtering of the image im in two dimensions.
• Each output pixel contains the median value in the 3 x 3 neighborhood around the corresponding pixel in the input image. It pads the image with zeros on the edges, so the median values for points on the edge of the image may appear darker.
• Median filtering is most often used to reduce "salt and pepper" noise.
• A median filter is more effective than convolution when the goal is to simultaneously reduce noise and preserve edges.
Harris Corner Detector
Shifting the window in any direction should yield a large change in appearance
-aka what happens at a corner!
Optical Flow (Liu)
• Found YouTube clip of Olympic diver: https://www.youtube.com/watch?v=djou2oLUeuo
• Clipped the video into a 3 second clip of just the action of diving
• Converted the clipped video into a sequence of jpg images• Example:
• Made a loop in demo flow to run through the sequence of diving images
• Took the optical flow images and converted them into an animated gif:Olympic Diver: http://makeagif.com/I27cPy
SVM (Support Vector Machine)
Pick classifier where the distance between the support vectors and the linear classifier is maximized.
Project Preference 1Project: Multimodal data analysis for the
detection of Attention Deficit Hyperactive Disorder
Mentor: Soumyabrata Dey
Began his reading most recent paper on the project
Have taken discrete systems which has graph theory which will help because: looking at the brain as a series of nodes and edges

I know python
Looked at papers on deep learning
