Hello, I made a matlab programm to track the center of 2 circles. Now, I would like to make a GUI to show the video runing AND the distance beetewen the two markers. I succed to display the distance of the 2 markers, but the probleme now is that in the while line 202 (at the end), I am unable to know what I have to write after "set(handles.Video,...." to display my video on the axes taged Video (cf attachment). I don't know if I have to write it in or after the "while" or if the syntax to run the video is usable with the syntax I want.
I past all the code, but the problem is in the while (at the end)
function varargout = HARMO_GUI(varargin)
% HARMO_GUI MATLAB code for HARMO_GUI.fig
% HARMO_GUI, by itself, creates a new HARMO_GUI or raises the existing
% singleton*.
%
% H = HARMO_GUI returns the handle to a new HARMO_GUI or the handle to
% the existing singleton*.
%
% HARMO_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in HARMO_GUI.M with the given input arguments.
%
% HARMO_GUI('Property','Value',...) creates a new HARMO_GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before HARMO_GUI_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to HARMO_GUI_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

Try putting a "drawnow" just before the end of your loop.

Writing the text with the distances is already working. Now I just try to display my video on the axes called video (picture in attachment).The video is already displayed but in an other windows
