Pixel Bus In when Input Valid is TRUE, contains one of the following: valid pixel data, an end of line signal, or an end of image signal.

	Pixel Data is the value of the pixel. A is the value of the alpha plane. R/H is the red or hue value of the first color plane, depending on the color mode. G/S is the green or saturation value of the second color plane, depending on the color mode. B/L is the blue or luminance value of the third color plane, depending on the color mode.
	DV Data valid. Determines whether the Pixel Data element should be use (TRUE) or ignored (FALSE).
	EOL End of line. When TRUE, indicates that the end of the line has been reached.
	EOI End of image. When TRUE, indicates that the end of the image has been reached.
	Data Type is used in the block diagram for determining the type of the Pixel Bus. Unused during processing and gets optimized out of the compiled bit stream.

Mask Pixel Bus In is an image specifying the region in the image to use for the calculation. Only those pixels in the original image that correspond to an equivalent non-zero pixel in the mask image are used for the calculation. The entire image is used in the calculation if Mask Pixel Bus In is not connected.
