"Point operations are defined as functions that are performed on each pixel of an image, independent of all other pixels in that image. Operations can be unary, meaning that a single image is modified, or they can be binary, which means that two images are combined in some manner. In certain situations, a point operation may be tertiary, implying that three images are used. Point operations are a very powerful class of image functions that can be cascaded one upon another to create interesting and useful results. "

more simply....individual pixels in an image are modified based on their indiviual value.   an example is, modiying color threshold or balance.....if pixel A is a certain color value of red....then change that pixel to orange.
Photoshop filters are a good example....'inverting' the contrast, solarizing, etc...

hope that helps.
