Object Localization Using Saliency Maps

- 1 min

I’m participating in fellowship.ai; and one the projects I was working on involved object localization. Specifically, how to do it if we only have class labels (no bounding box or segmentation info).

Turns out we can use class activation maps, using techniques such as GradCAM or GradCAM++ to obtain a map from any classifier; which can then be converted into a bounding box.

See our team’s article describing the approach in more detail.
