get values proportional to most occurence

here is my code

%Display the transform axes(handles.axes14); imshow(imadjust(mat2gray(H)),[],'XData',theta,'YData',rho,... 'InitialMagnification','fit'); xlabel('\theta (degrees)'), ylabel('\rho'); axis on, axis normal, hold on; x=theta(P(:,2)); [occ,ent]=hist(x,unique(x));

this will give me 1000 peaks as i chose 1000 for peaks

now i want to only filter out values which have an occurence more than 10 for a certain value of theta. i am quite new to matlab.

so that these are the values that are plotted on the matrix and not all the peaks are plotted on the matrix.

if you understand what i am trying to explain

y = rho(P(:,1)); plot(x,y,'s','color','red');

Please don't include extraneous material in your question (such as the IMSHOW and PLOT statements).

I assume your question is that you have:

[occ,ent] = hist(x, unique(x));

and you want to only extract those values of ENT where OCC > 10.

You can use the FIND command to identify indices that match a criterion. For example:

x = ceil(rand(1,5000)*100);    % make some sample data 
[occ,ent] = hist(x,unique(x)); % get the counts

Find indices where occurrences are greater than 10

indices = find(occ > 10);

Extract the associated entries

filteredOccurreces = occ(indices);
filteredEntries = ent(indices);

Thanks

i already figured it out. i used the same command you said i got it from this site so i used that to get values which occured the most. i joined occ and ent on each column for same variable so row 1 will show entry and the number of occurance. i then look for most occurance and get the corresponding column number of the entry. place the values in a new variable.

then i place x and y in 2 row variable so i can look for the theta value in x and get the corresponding y value then separate the x and y variable and then plot it on the matrix.
