Suppose you are running a sliding window detector to find text in images. your input images are1000x1000 pixels. you will run your sliding windows detector at two scales, 10x10 and 20x20 (i. e.,you will run your classifier on lots of 10x10 patches to decide if they contain text or not; and alsoon lots of 20x20 patches), and you will "step" your detector by 2 pixels each time. about howmany times will you end up running your classifier on a single 1000x1000 test set image?
