Img(row, column) = 1
Will set the pixel (row, column) to white.

Binary images are of class logical and take on values true and false. To set a pixel at some row and column to appear white, set it to true
binaryImage(row, column) = true;
It's possible to set whole irregularly shaped regions (many pixels) to true if you have some mask or other binary image:
binaryImage1(binaryImage2) = true;
If you don't know the coordinates of your black pixels that you want to turn white, then you need to identify them somehow and for that you should attach an image so we can tell you how to do that.
