What are the effects of exceptions on performance in Java?

...situation where the failure is not exceptional. Cutting that down to only 10% massively cuts the performance hit.

Then stretch it to 1100 x 1000 on 1666 x 1000 screen, leaving 566 x 1000. So your second band now needs to adjust over only 433 to 566, w...

Algorithm to compare two images

However, one algorithm may find all the matches, but also have a large 20% false positive rate, so there are several ways to rate your algorith...

Which rounds to 8 so that's a bad example. But it still illustrates that you are taking 9.09% of 9 and not 8.8. So there might be some numbers...
