Image processing

Question 1

When dealing with an image as an array of x, and y coordinates. What is the conversion?

Answer 1

for an array -> [rows,coloums]
So -y,x in coordinates.

Question 2

Is the notation height then width or width then height in an image?

Answer 2

height then width

Question 3

How does SLIC from Skimage work?

Answer 3

It defines the distance in colour-space metric, initialises centres uniformly on the image and iterates till convergence.

Question 4

Give the colour-space metric equation

Answer 4

Distance = sqrt( (normalised_colour_distance)**2 + (normalised_spatial_distance) )
