imquantize
Quantize image using specified quantization levels and output values
Syntax
Description
quantizes image quant_A
= imquantize(A
,levels
)A
using specified quantization values contained
in the N-element vector levels
. The
quantized image quant_A
is the same size as
A
and contains N+1 discrete integer
values in the range 1 to N+1. The integer values are determined
by the following criteria:
If
A(k)
≤levels(1)
, thenquant_A(k)
=1
.If
levels(m–1)
<A(k)
≤levels(m)
, thenquant_A(k)
=m
.If
A(k)
>levels(N)
, thenquant_A(k)
=N+1
