首爾二、三事

因為不知道怎麼問「這是幾人份？」，所以最後指著綜合口味的pizza並豎起右手食指！比pizza hut的大pizza小一點，應該可以吃完，不過吃掉3/4後因為還想繼續探險，所以打包了剩下的1/4！可樂也剩下半瓶。因為路上很冷，所以回到旅館時已經是冰pizza跟冰可樂了！（加可樂7000￦）

每天轉電視都有人下棋！看過一局等級似乎不高的棋，所以應該不全是職業棋士在下。如果是以前我一定會很羨慕韓國人！

另外每次轉電視都有一台在播星海一的對戰！

Lua + Image

I usually works with images, and have to write many code even only for a simple testing. Now I try to implement toolkits with Lua, hope that I can do more things by the help of script. With the script below:

function Main()

    local img0 = Urd.CImage32F();
    local img1 = Urd.CImage32F();

    img0:Load("D:/img/NTU/106009.JPG", Urd.ChannelL);


    CImageProcessor.GaussianSmooth(img1, img0, 7, 7, 2.0, 2.0);
    CImageProcessor.OperateImgNImg(img1, img0, img1, Urd.OperatorSub);
    CImageProcessor.OperateImgNScalar(img1, img1, 10.0, Urd.OperatorMul);

    img1:Save("D:/img/ttt.jpg", Urd.ChannelL);

end

I got this result :


They are "C like" since I implement them in C with the same function and class name. Hope this will become useful in a few days.

Nothing special, I just wanna update my blog.

G1S was down !

Now I have 2 choices: buy a new PC, or repair G1S. G1S was down, but ASUS never let me down. I won`t buy their notebook again.
