The problem considered in this article∗is how to evaluate image segmentations objectively. An image segmentation is the partition of an image into its constituent parts. Until recently, the evaluation of image segmentations has been largely subjective. Much work has been done in developing metrics for evaluating segmentations with respect to ground truth images. However, little has been done in...

Our actions are a product of mental states that represent how the world is, how we want it to be, and so forth. Such is central to our conception of ourselves as rational agents.

The aims of this study were twofold: (1) to determine if youth will play a game with tobacco-related information and themes and (2) t...

Content-based image retrieval is starting to become an increasingly important factor in medical imaging research and image management systems. Several retrieval systems and methodologies exist and are used in a large variety of applications from automatic labelling of images to diagnostic aid and image classification. Still, it is very hard to compare the performance of these systems as the use...
