??? Undefined function or method 'Mouse' for input arguments of type 'char'.

this is the error when I try to run this code, pls help!!!

Code for recognising my hand on the webcam to move the mouse pointer:

vid = videoinput('winvideo',2,'rgb24_320x240'); %preview(vid) % background template bgrnd=getsnapshot(vid); final_bg_template = rgb2gray(bgrnd); cx=100; cy=100; while(1) % extraction of hand frgrnd=getsnapshot(vid); final_frgrnd=rgb2gray(frgrnd); img_subtracted=final_frgrnd-final_bg_template; % binary image of hand % imview(img_subtracted); [m n]=size(img_subtracted); for i=1:m for j=1:n % [EDITED, Jan Simon]: Was "j-1:n" if(img_subtracted(i,j)<25) img_subtracted_bin(i,j)=0; else img_subtracted_bin(i,j)=1; end end end [m n]=size(img_subtracted_bin); % xy coordinates of topmost point for p=m:-1:1 for q=n:-1:1 if(img_subtracted_bin(p,q)==1) x_top=q; y_top=p; end end end cy=x_top; cx=y_top; % [cx cy] = centroid(img_subtracted_bin); set (0,'PointerLocation',[cx*4 cy*3.33]); imshow(img_subtracted_bin); end

There is no reference to Mouse in the code you show. Please show the traceback from the place the message is encountered back to the code you posted.

Better yet would be to merge the above code and the traceback in to your previous question.
