Question

Please, can any one explain to me these two questions:

what does it mean by 20 k iteration? and what does it mean by 20 k image?

Answer 1

1. k normally represents 1000
2. Here possibly you have 20,000 images
3. Each image has to undergo some calculation
4. Initially calculations made for first image,then second ,and so on
5. This process will be evaluated for all 20,000 images
6. Calculations made for first image comes under iteration 1,second image iteration 2
7. Calculations for 20,000th image will be made at 20,000 th iteration .i.e. 20 k th iteration
