Well, there are various places. For example, indexing image data is a natural source of convergence between data mining and computer vision. In order to cluster images, you will probably want to have a tight interplay of computer vision and data mining, too.
Or for example Robust Segmentation of Relevant Regions in Low Depth of Field Images, an image segmentation method that is in fact based on DBSCAN clustering. I bet you can come up with many such examples when you look around. Say: aligning a stack of panorama images requires actually some kind of data mining, too. At least when you have a few thousand SIFT keypoints to work with.
