Edge detection
What
is an edge and where does it come from
Edge
detection by differentiation
Image
gradients
continuous
and discrete
filters
(e.g., Sobel operator)
Effects
of noise on gradients
Derivative
theorem of convolution
Derivative
of Gaussian (DoG) operator
Laplacian
operator
Laplacian
of Gaussian (LoG)
Canny
edge detector (basic idea)
Effects
of varying sigma parameter
Approximating
an LoG by subtraction
Hough
Transform (lines, circles, generalized (from midterm))
