OpenCV 2.3 C ++基本图像处理

Question

What is the best way to open an image, manually manipulate the pixels as floats, normalize the pixels back to 8bit int values (0-255) and save the new image.

I found deferment codes use different variable types and commands, should i use Iplimage or mat, imread, and so on...

i would really appreciate a code example

Thanks!
