- Pixel depth refers to the number of bits used by each pixel and determines the number of colors that each pixel may have. ( )
- ______ operation takes a single input image into a single output image in such a way that each output pixel's gray level depends only upon the gray level of the corresponding input pixel.
- Motion vector tries to match each block in the actual picture to content in the previous picture. Matching is made by shifting each of the _____x_____ blocks of the two successive pictures pixel by pixel each direction.
- Each pixel has two attributes at least: ______ and gray-level value.
