IMAQ FPGA Quantify VI

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.
	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 a labeled version of the source image that specifies the regions to quantify. Only the pixels in the original image that correspond to an equivalent pixel in the mask different from 0 are used for the quantification. Each pixel in the image mask indicates, by its value, which region belongs to the corresponding pixel in Image. Up to 255 different regions for an 8-bit image, or 65,535 regions for a 16-bit image, can be quantified directly from the image. A quantification is performed on the complete image if the Mask Pixel Bus is not connected.

Input Valid specifies whether the next data point has arrived for processing. Wire the Output Valid output of an upstream node to this input to transfer data from the upstream node to this node.

Ready For Output specifies whether downstream nodes are ready for this node to return a new value. The default is TRUE. Use a Feedback Node to wire the Ready for Input output of a downstream node to this input of the current node.

Note  If this terminal is FALSE during a given cycle, the output valid terminal returns FALSE during that cycle.

Report is a cluster containing the quantification data relative to all the regions within an image, or to the entire image if Mask Pixel Bus In is not connected. This cluster contains the following elements:

	Area (pixels) returns the analyzed surface area in pixels.
	Maximal Value returns the largest pixel value.
	Minimal Value returns the smallest pixel value.
	Mean Value returns the mean pixel value.
	Standard Variation indicates the distribution of the pixel values in relation to the average. The higher this value, the better the distribution of the pixel values.
	Label Max returns the percentage of the analyzed surface in relation to the complete image.

Output Valid returns TRUE if this node has computed a result that downstream nodes can use. Wire this output to the Input Valid input of a downstream node to transfer data from the node to the downstream node.

Ready for Input returns TRUE if this node is ready to accept new input data. Use a Feedback Node to wire this output to the Ready for Output input of an upstream node.

Note  If this terminal returns FALSE during a given cycle, LabVIEW discards any data that other nodes send to this node during the following cycle. LabVIEW discards this data even if the Input Valid terminal is TRUE during the following cycle.
