Can anyone help me with index in position 2 exceeds array bounds (must not exceed 1). in line 39. My project is offside detection in football but i don't even know what offside exactly is i don't know is my code gonna work properly :( im stuck
clc
close all
clear all

img=imcrop(img,[5 2 725 584]);
imtool('offside.jpg')

img_h=rgb2hsv(img);
h=img_h(:,:,1);
s=img_h(:,:,2);
v=img_h(:,:,3);
level=graythresh(img);
[r c]=size(h);
for i=1:r
for j=1:c
if (h(i,j)>=0.01 && h(i,j)<=0.99)
out(i,j)=255;
else
out(i,j)=0;
end
end
end
t=bwareaopen(out,300);
se=strel('disk',0);
bw=imclose(t,se);
[B,L]= bwboundaries(bw,'noholes'),disp(B);
hold on
for k = 1:length(B)
boundary=B(k);
plot(boundary(:,2), boundary(:,1), 'w', 'LineWidth',2)
end
fprintf('Nesneler isaretlenmistir. Toplam nesne sayisi=%d\n', length(B))

We cannot rectify error unless the required input is given.
Any ways check this variable boundary, it seems it don't have two columns.

yes,sir,may be upload 'offside.jpg' to debug
may be check the 39 line,is it two columns matrix

The first output of bwboundaries is a cell array.
boundary1=B(k);
applied to a cell array is going to result in a scalar cell -- which is not going to have two columns.
At that point you need the data inside the cell array, B{k}
