i i have four coordinates which correspond to (x,y,width,height) . I can draw a rectangle over an image from this script but it is a filled rectangle with redcolor i want a a bounding box or a transparent rectangle.It might be very trivial but i am not a regular coder.
I=imread('000027.jpg');
figure,imshow(I)
hold on
rectangle('Position',[203, 147, 218, 162],'FaceColor','r')
Thanks guys

Change FaceColor to EdgeColor:
rgbImage=imread('peppers.png');
imshow(rgbImage)
hold on
rectangle('Position', [203, 147, 218, 162],...
'EdgeColor','r', 'LineWidth', 3)
