Why ti pick points using ginput? You can use imcrop right?

You need to define Rect to use the ginput points.

I = imread("image.jpeg") ; 
imshow(I) ; 
[Px,Py] = ginput(2) ; 

Px = round(Px) ; Py = round(Py) ; 

R = [Px(1) Py(1)  Px(2)-Px(1) Py(2)-Py(1)] ;  %[ x y W H] 
I1 = imcrop(I,R) ; 
figure
imshow(I1)

Play around with creating R...I am not sure whether they are correct here.

NOTE: While using imcrop also you do the same, select left top first and then bottom right. You define a rectangle.
