Problems displaying video

[Martin Noblia]

Hello 
everyone, my problem is that when attempting to display a video with the
 following code:

for i=1:100

imagen=aviread('/home/elsuizo/Escritorio/tpfinalvision/imagenestoma1/video2.avi',i);

%*********Processing frame****************

%im2=rgb2gray(imagen);

%im3=im2<100;

%fil=fspecial('sobel');

%im_fi=imfilter()

%***************************

imshow(imagen)

endfor

The output is :

software tools, thanks in advance
