Final answer:
The best pixel image compositing process fixes problematic pixels such as dead pixels, stuck pixels, and hot pixels. These imperfections are corrected by interpolating the data from surrounding pixels to minimize or eliminate the visible issues.
Step-by-step explanation:
The problematic types of pixels that the best available pixel image compositing process fixes are commonly referred to as dead pixels, stuck pixels, and hot pixels.
Dead pixels are those that do not light up at all and appear as black spots on the screen. Stuck pixels, on the other hand, are permanently 'on' and typically show up as bright red, green, or blue spots. Hot pixels are similar to stuck pixels but usually appear only when the camera's sensor is heated, such as during long exposures, and they are more common in photographs than on screens.
Image compositing software employs various techniques to fix these issues by interpolating the correct color values from the surrounding pixels, thereby making the imperfections less noticeable or entirely invisible.
