is this possible

Hi,
Folllowing is the code and app design
classdef app1 < matlab.apps.AppBase % Properties that correspond to app components
properties (Access = public) UIFigure matlab.ui.Figure UIAxes matlab.ui.control.UIAxes UIAxes2 matlab.ui.control.UIAxes Button matlab.ui.control.Button end properties (Access = public) cam; end % Callbacks that handle component events
methods (Access = private) % Code that executes after component creation
function startupFcn(app) app.UIAxes2.Visible = 'off'; evalin("base", 'clear cam'); app.cam = webcam; frame = snapshot(app.cam); im = image(app.UIAxes, zeros(size(frame), 'uint8')); axis(app.UIAxes, 'image'); preview(app.cam, im); end % Button pushed function: Button
function ButtonPushed(app, event) img = snapshot(app.cam); image(app.UIAxes2, img); app.UIAxes2.Visible = 'off'; end end % Component initialization
methods (Access = private) % Create UIFigure and components
function createComponents(app) % Create UIFigure and hide until all components are created
app.UIFigure = uifigure('Visible', 'off'); app.UIFigure.Position = [100 100 640 480]; app.UIFigure.Name = 'UI Figure'; % Create UIAxes
app.UIAxes = uiaxes(app.UIFigure); title(app.UIAxes, 'Title') xlabel(app.UIAxes, 'X') ylabel(app.UIAxes, 'Y') app.UIAxes.Position = [26 270 300 185]; % Create UIAxes2
app.UIAxes2 = uiaxes(app.UIFigure); title(app.UIAxes2, 'Title') xlabel(app.UIAxes2, 'X') ylabel(app.UIAxes2, 'Y') app.UIAxes2.Position = [25 43 300 185]; % Create Button
app.Button = uibutton(app.UIFigure, 'push'); app.Button.ButtonPushedFcn = createCallbackFcn(app, @ButtonPushed, true); app.Button.Position = [447 249 100 22]; % Show the figure after all components are created
app.UIFigure.Visible = 'on'; end end % App creation and deletion
methods (Access = public) % Construct app
function app = app1 % Create UIFigure and components createComponents(app) % Register the app with App Designer
registerApp(app, app.UIFigure) % Execute the startup function
runStartupFcn(app, @startupFcn) if nargout == 0 clear app end end % Code that executes before app deletion
function delete(app) % Delete UIFigure when app is deleted
delete(app.UIFigure) end endendError you are facing instantiates that the code is not able to access the camera object at that instant.
Hope it helps!!
Create a property for your app class to hold the image.
You appear to be using appdsigner. In appdesigner's code view, on the left panel look for "properties" and add a new one, call it Image (or b, but probably Image is better).
Remove your global declaration.
Your upload callback should look like
function UploadButtonPushed2(app, event) [file,path] = uigetfile({'*.png';'*.jpg';'*.tiff';'*.jpeg'},... 'File Selector'); a=imread(file) app.Image=imcrop(a,[145 58 370 370]) %%%%%%%%%%% this line edited
imshow(app.Image,'Parent',app.UIAxes) %%%%%%%%%%% this line edited title(sprintf('%s',file),'Parent',app.UIAxes)endand your deconv button callback should look like
function DeconvoluteButtonPushed(app, event) % load(b) % there is the issue I want the image variable b from UploadButtonPushed2 to DeconvoluteButtonPushed
PSF = fspecial('gaussian',[371 371],app.GaussianVarianceEditField.Value) [J,psfr]=deconvblind(app.Image,PSF,app.IterationsEditField.Value) %%%%% this line edited
figure subplot(131) imagesc(J) colorbar subplot(132) imagesc(psfr) colorbar subplot(133) imagesc(PSF) colorbarend
