hey, i am doing a project on 'moment preserving thresholding' which essentially retrieves two threshold values from an input 'gray scale image'.
for getting the threshold values we perform certain operations and obtain p,p1,p2 values.
the value of threshold is then selected as follows, 'the thresholds t,t1, can be found from the histogram of image by choosing 't' as the p-tile and 't1' as (p+p1)-tile'
the values of p,p1,p2 are less than one(say p=0.361,pl=0.277,p2=0.362;).
my problem is how to obtain values from the histogram for such fraction values, since the values of p,p1,p2 are fractions less than 1.
this below is the test data set...
a=[10 8 10 9 20 21 32 30 40 41 41 40 12 10 11 10 19 20 30 28 38 40 40 39 10 9 10 8 20 21 30 29 42 40 40 39 11 10 9 11 19 21 31 30 40 42 38 40];
'a' is of size 4*12.
p=0.361; pl=0.277; p2=0.362;
selected thresholds are t=18,t1=30
can anyone help me to get over this problem.
