· 25.2.03 : Regarding exercise 5:

Due to a misunderstanding, bonus points were not awarded for the extra mosaic construction part. This misunderstanding will be corrected. As a result, grades of Ex. 5 will be raised by 5 points.
As to the complaints about points being subtracted for "inaccurate results": This may not have been a clear enough comment. In most cases the bulk of points was subtracted due to a *bug* in your program, which led to such results. In many of the programs there was no transitivity, i.e., in one direction "align(im1, im2)" might have produced reasonable results, but when we reversed the order of the images, "align(im2, im1)" did not produce the same results with opposite sign (as it should), but instead produced erroneous results (usually more than 1 pixel off, which is a *visible* misalignment error, even if you do not know the correct shift!) This is a bug, which usually led to approximately 20 points being deducted from the grade. We would like to stress that many students did write good programs with accurate results and no bugs, so this was not an unreachable goal.

If anyone has any further questions regarding these issues, you are more then welcome to contact Tal Hassner by mail or at 4443.
