Why I am getting Error?

CODE

clear all; close all; imtool close all; clc;

imag1 = imread('C:\Users\Explorer\Documents\MATLAB\ASL_signs\A.jpg');

imag2 = imread('C:\Users\Explorer\Documents\MATLAB\ASL_signs\A2.jpg');

imag3 = imread('C:\Users\Explorer\Documents\MATLAB\ASL_signs\A3.jpg');

imag4 = imread('C:\Users\Explorer\Documents\MATLAB\ASL_signs\A4.jpg');

imag5 = imread('C:\Users\Explorer\Documents\MATLAB\ASL_signs\A5.jpg');

v1= descrip_blob2(imag1)

v2= descrip_blob2(imag2)

v3= descrip_blob2(imag3)

ERROR

Warning: Iterations terminated prematurely because no part of the contour lies within

the image domain. If the range of pixel values in the input image is small (such as

0-1), consider increasing the range by multiplying the input image with a scale

factor. Also, consider specifying a different initial contour position in MASK.

Error in descrip_blob2 (line 57)

thisBoundary = boundary{2}; % Or whatever blob you want.

I think we will need to see the images.

My guess would be that your JPEG files are not in a format that 'imread' expects. Try specifying their format.
