Question 1:

d. Perform Canny edge detection, with different parameters. e. Calculate Harris corners for 2 sets of parameters.

Question 2 - Create a blob detector using Laplacian of Gaussian [LoG]:

1. Build pyramids:
   1. Create Gaussian filters with increasing scale.
   2. Create Pyramids with corresponding filters. Normalize by sigma^2.
2. Non maximum supression - Search for local maxima both in image space and in scale space.
3. Present results over various scales.
