When enlarging an image, for example, adding five vertical seams to the original image. The program first finds five seams based on the original image and stores the coordinates of the points of the original image in the so-called SeamVector. When come to enlarge the image, adds one seam after the other. After adding one seam, the width of the image has changed, then the coordinates of the points stored in the SeamVector must also be changed in order to fit the enlarged image. Otherwise, the program may duplicate the false points. When I began designning my own code in C++, I came up with the same problem as well. I think a way to solve this is to arrange the seams stored in the SeamVector from left to right. Say, the column number of the last row of the five seams that I want to add is 2,5,7,4,3. Then I can arrange them like 2,3,4,5,7. Then the real column number that I add step by step is 2, 3+1, 4+2, 5+3, 7+4. This is my way of solving the problem, but I came up with it just now and have not implemented it yet. Thanks for your program, I designed my C++ code using the same method as yours. Hoping to disscus more details regarding seam carving with you. My name is Xing,Xiaoxiong, a senior student from Beijing Normal University. I found a bug in the program.

I downloaded your matlab program and find some questions which I cannot understand. In your program, it first generates a picture with the function findEnergy, then with the function findSeamImg, it creates the seam image based on which the seam is found. However, I found that the result of the findseamimg function is not Seam Energymap (figure 4 in the Notes file). Can you explain it? Have you received my email?

So, pressing DVD would bring me to High Performance, while QuickPlay would switch to Power Saving. It's quite neat, considering the fact that I can now do this using the IR remote controller too. The drawback in using "Launch" is that it pops up a command prompt for a fraction of second. I also built an executable myselfe, parsing the parameters "my_dvd" and "root", but while I am running this executable from the command line is working, well, the situation changes when pressing the buttons. It simply ignores me. Nevertheless, I may be doing something wrong in writing the code to that executable [dunno exactly what 8-| ]. Anyways, thanks for the tips I've learnt here and at the Tablet PC Forum [I needed to sign up for an account there to speak my joy out :P so it kinda blew me off :P]. Yours.

Great tip - thanks a lot. The problem is that the brightness control doesn't appear in my mobility center anymore. I really do not have a clue why this is missing. Any idea? Hi.
