matlab 怎么读取图片

Answer 1

matlab 怎么读取图片
以这样做：
function pushbutton1_Callback(hObject, eventdata, handles)
[fname, pname, index] = uigetfile({'*.jpg'; '*.bmp'}, '选择图片');%读取图片
str3 = [pname fname];
axes(handles.axes1);
imshow(str3);
handles.img = str3 %将图片赋值于句柄
guidata(hObject, handles);%更新句柄

function pushbutton2_Callback(hObject, eventdata, handles)
img1 = handles.img; %将图片赋给img1，就可以对img1进行操作了
