## Announcements

• May 21
• 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.
• May 15
• On HW3 problem 2(b), I forgot to mention that you need to L1-normalize 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, 3:00-6:00pm, in 207 Center Hall.
• May 1
• 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.)
• May 1
• 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].
• Apr. 30
• 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.)
• Apr. 29
• 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 y-direction rather than in the x-direction 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.)
• Apr. 18
• 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, 3:00-6:00pm.
• 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 e-mailing 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.
• Apr. 4
• 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.
• Please join the class mailing list by sending an email to majordomo@cs.ucsd.edu with the body of the message as follows:

• Apr. 2
• 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.
