 The final due date for the homework assignments has been extended by
one week: the new due date is June 4.
 For the final exam you will be allowed to bring two 8.5" by 11"
sheets of paper with writing on both sides.

 On HW3 problem 2(b), I forgot to mention that you need to
L1normalize each kernel, i.e. divide each filter by the sum of its
absolute values. The corrected version is now posted on the main
page. (Thanks Josh.)
 May 13
 The final exam is confirmed for Thursday, June 13, 3:006:00pm, in
207 Center Hall.

 The little p's in HW2 problem 5(a) should be big P's. The ps/pdf
files onthe web page have been updated with this correction.
(Thanks to Satya and Junwen for pointing this out.)

The rows of the A matrix in the eight point algorithm are as follows:
[xr*xl, yr*xl, xl, xr*yl, yr*yl, yl, xr, yr, 1].

For the algorithm EUCLID_REC in T&V (page 166), the method for resolving the
sign ambiguity is incorrect. The subparts of part 4 (a and b) should be switched.
That is, E should be updated before T is updated. If they are not done
in this order, the error introduced by the incorrect E will not be resolved
and the algorithm will loop indefinitely.
Also a helpful hint is to make sure that P and p are not confused...this
will lead to errors that are very difficult to decipher. (From Josh.)

The book has a mistake (T&V page 156) in that the process for undoing
the normalization is missing a transpose. The correct equation should
be F_bar=(Hr)T * F * Hl. This is the way it is presented in Hartley's
paper. If this transposition is left out, the translation will be in
the ydirection rather than in the xdirection and the lines will be
off by a little. (From Josh.)
 The p_i and d in the 2nd to last line of T&V Exercise 7.6 are
missing a hat and a bar, respectively. (Thanks to Josh and Bianca for
spotting this.)

 For those of you looking to bone up on eigenvalues and singular
values, I put a link to a neat article by Cleve Moler
of the Mathworks on the Matlab "eigshow" demo.
 According to Studentlink, the final exam will be Thursday, June 13, 3:006:00pm.
 Apr. 14
 In HW1, problem 7, the function "imreshape.m" should be
"reshape.m". (Thanks to Satya for pointing this out.)
 Apr. 10
 Please put "CSE 252" in the subject line when emailing me with
questions about the course.
 Apr. 7
 I decided to drop problem #9 (on SVD line fitting) from assignment
#1. It might reappear on a later assignment, however. If you already
did it, or would like to do it anyway, you can have some extra credit
points for it.

 The grading and course policies are now available on the main
course web page; please read them carefully and contact me if you have
any questions.

 The third row of the camera projection matrix I wrote on the board
today was incorrect: please see T&V p. 39 for the correct entries
(modulo a sign factor).
 Handout on Matlab posted on course web page. This is not a
required assignment, but it is recommended if you have not used Matlab
before.
