i am deepthi i am implementing the project in CBIR...i have to implement for large image database...i dono how to use large image db in base.txt.. plz help me....
function varargout = main(varargin)
% MAIN M-file for main.fig
% MAIN, by itself, creates a new MAIN or raises the existing
% singleton*.
%
% H = MAIN returns the handle to a new MAIN or the handle to
% the existing singleton*.
%
% MAIN('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MAIN.M with the given input arguments.
%
% MAIN('Property','Value',...) creates a new MAIN or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before main_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to main_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

FYI, (in case anyone is wondering) CBIR is Content-Based Image Retrieval. For example "retrieve for me all images of beaches".

I notice you have edited the question, but you have not responded to my Answer.

Set breakpoints and examine variables. You need to find out why you're passing a null filename into imread(), and some arrays (X,map,Y,map1) not having the proper size. Using the debugger you will be able to figure this out. We can't since we don't have your .fig file and don't have your images.

Your file base.txt is either empty or has a blank first line.

Are you sure you wrote the code?
It should be obvious that decompose() is going to return arrays given that input.
What is not obvious is why you repeatedly apply decompose() to the same inputs "for j = 1 : 5". The body of your loop has no reference to j.
