signal so you can process it with one 2-D Histogram block. Set the Number

8 Use the 2-D Histogram block to calculate the histogram of the R , G, and B

values in the image. Accept the default parameters.

The R, G, and B values input to the 2-D Histogram block are

double-precision floating point a nd range between 0 and 1. The block

creates 256 bins between the maximum and minimum input v alues and

counts the number of R, G, and B values in each bin.

9 Use the

Bus Selector block to expand the input signal into three separate

R, G, a

nd B, signals. You must set the block parameters of this block after

you co

nnect a signal to i ts input p ort. You configure this block later in

this p

rocedure.
