With the intention to create an enhanced visual explanation in terms of visual sharpness, object localization and explaining multiple occurrences of objects in a single image, we present Smooth Grad-CAM++ \footnote{Simple demo: http://35. 238. 22. 135:5000/}, a technique that combines methods from two other recent techniques---SMOOTHGRAD and Grad-CAM++.
