can anyone suggest a way out of this and explain why is this error is occuring.

allcount=Inf;
     I = imread('frame1359.jpg');
     count=0;
     myFilterHandle = @myFilter;
     blockyImage = blockproc(I,[20 20], myFilterHandle);
     allcount(2,1)=count;
     disp(count);
       function singleValue = myFilter(blockStruct)
          s=(blockStruct.data);
          r=imresize(s,[227 227]);
  % net is a classifier already trained and loaded
          pred=classify(net,r);
          if pred =='1'
              count=count+1;
          end
  % this is just for blockproc to keep running this is line (imresize) is not important 
  %if i dont use this blockproc wont proceed to next iteration.
          singleValue=imresize(blockStruct.data,0.5); 
       end
