显示 更早的评论
thisFrame = read(vid, framesToRead(h));
pos1=app.CTRLVEditField.Value
str = strrep(pos1, '[', ''); % Odstranění závorek
str = strrep(str, ']', '');
values= split(str, ','); % Rozdělení řetězce podle čárky
pos = str2double(pos1) % Převod na čísla
cr=imcrop(thisFrame,pos);
Hello, I work in App designer, where I put into Edit filed the area I would like to crop in this type [1 2 3 4], but in the position cr=imcrop ... the matlab says
Input number 2, RECT, is expected to contain 4 elements.
validateRectangle(spatial_rect,2);
images.internal.crop.parseInputsOverTwo(varargin{:});
How can I solve this problem. Thank you.

pos1 = "[1 2 3 4]";
pos = str2num(pos1)
