These two tasks are popular applications of convolutional neural networks. However, I don't understand the difference. According to one Caffe tutorial, it seems that the task of object detection is harder.

Does object detection define where the object is located in an image, or reveal how many of the object is in the picture...?

The difference is following. If you have to define the class of an image, it relates to the object classification task. If you have to define coordinates of an object on the image, then it is the object detection task.
